-
-/*
- * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
- * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * The conversion equations to be implemented are therefore
- *      Y  =  0.29900 * R + 0.58700 * G + 0.11400 * B
- *      Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B  + CENTERJSAMPLE
- *      Cr =  0.50000 * R - 0.41869 * G - 0.08131 * B  + CENTERJSAMPLE
- * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
- * Note: older versions of the IJG code used a zero offset of MAXJSAMPLE/2,
- * rather than CENTERJSAMPLE, for Cb and Cr.  This gave equal positive and
- * negative swings for Cb/Cr, but meant that grayscale values (Cb=Cr=0)
- * were not represented exactly.  Now we sacrifice exact representation of
- * maximum red and maximum blue in order to get exact grayscales.
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
- * the products by 2^16, with appropriate rounding, to get the correct answer.
- *
- * For even more speed, we avoid doing any multiplications in the inner loop
- * by precalculating the constants times R,G,B for all possible values.
- * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
- * for 12-bit samples it is still acceptable.  It's not very reasonable for
- * 16-bit samples, but if you want lossless storage you shouldn't be changing
- * colorspace anyway.
- * The CENTERJSAMPLE offsets and the rounding fudge-factor of 0.5 are included
- * in the tables to save adding them separately in the inner loop.

- * Copyright (C) 1991-1996, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains downsampling routines.
- *
- * Downsampling input data is counted in "row groups".  A row group
- * is defined to be max_v_samp_factor pixel rows of each component,
- * from which the downsampler produces v_samp_factor sample rows.
- * A single row group is processed in each call to the downsampler module.
- *
- * The downsampler is responsible for edge-expansion of its output data
- * to fill an integral number of DCT blocks horizontally.  The source buffer
- * may be modified if it is helpful for this purpose (the source buffer is
- * allocated wide enough to correspond to the desired output width).
- * The caller (the prep controller) is responsible for vertical padding.
- *
- * The downsampler may request "context rows" by setting need_context_rows
- * during startup.  In this case, the input arrays will contain at least
- * one row group's worth of pixels above and below the passed-in data;
- * the caller will create dummy rows at image top and bottom by replicating
- * the first or last real pixel row.
- *
- * An excellent reference for image resampling is
- *   Digital Image Warping, George Wolberg, 1990.
- *   Pub. by IEEE Computer Society Press, Los Alamitos, CA. ISBN 0-8186-8944-7.
- *
- * The downsampling algorithm used here is a simple average of the source
- * pixels covered by the output pixel.  The hi-falutin sampling literature
- * refers to this as a "box filter".  In general the characteristics of a box
- * filter are not very good, but for the specific cases we normally use (1:1
- * and 2:1 ratios) the box is equivalent to a "triangle filter" which is not
- * nearly so bad.  If you intend to use other sampling ratios, you'd be well
- * advised to improve this code.
- *
- * A simple input-smoothing capability is provided.  This is mainly intended
- * for cleaning up color-dithered GIF input files (if you find it inadequate,
- * we suggest using an external filtering program such as pnmconvol).  When
- * enabled, each input pixel P is replaced by a weighted sum of itself and its
- * eight neighbors.  P's weight is 1-8*SF and each neighbor's weight is SF,
- * where SF = (smoothing_factor / 1024).
- * Currently, smoothing is only supported for 2h2v sampling factors.

- * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
- * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
- * The conversion equations to be implemented are therefore
- *      R = Y                + 1.40200 * Cr
- *      G = Y - 0.34414 * Cb - 0.71414 * Cr
- *      B = Y + 1.77200 * Cb
- * where Cb and Cr represent the incoming values less CENTERJSAMPLE.
- * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
- *
- * To avoid floating-point arithmetic, we represent the fractional constants
- * as integers scaled up by 2^16 (about 4 digits precision); we have to divide

-/*
- * In the current system design, the main buffer need never be a full-image
- * buffer; any full-height buffers will be found inside the coefficient or
- * postprocessing controllers.  Nonetheless, the main controller is not
- * trivial.  Its responsibility is to provide context rows for upsampling/
- * rescaling, and doing this in an efficient fashion is a bit tricky.
- *
- * Postprocessor input data is counted in "row groups".  A row group
- * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size)
- * sample rows of each component.  (We require DCT_scaled_size values to be
- * chosen such that these numbers are integers.  In practice DCT_scaled_size
- * values will likely be powers of two, so we actually have the stronger
- * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.)
- * Upsampling will typically produce max_v_samp_factor pixel rows from each
- * row group (times any additional scale factor that the upsampler is
- * applying).
- *
- * The coefficient controller will deliver data to us one iMCU row at a time;
- * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or
- * exactly min_DCT_scaled_size row groups.  (This amount of data corresponds
- * to one row of MCUs when the image is fully interleaved.)  Note that the
- * number of sample rows varies across components, but the number of row
- * groups does not.  Some garbage sample rows may be included in the last iMCU
- * row at the bottom of the image.
- *
- * Depending on the vertical scaling algorithm used, the upsampler may need
- * access to the sample row(s) above and below its current input row group.
- * The upsampler is required to set need_context_rows TRUE at global selection
- * time if so.  When need_context_rows is FALSE, this controller can simply
- * obtain one iMCU row at a time from the coefficient controller and dole it
- * out as row groups to the postprocessor.
- *
- * When need_context_rows is TRUE, this controller guarantees that the buffer
- * passed to postprocessing contains at least one row group's worth of samples
- * above and below the row group(s) being processed.  Note that the context
- * rows "above" the first passed row group appear at negative row offsets in
- * the passed buffer.  At the top and bottom of the image, the required
- * context rows are manufactured by duplicating the first or last real sample
- * row; this avoids having special cases in the upsampling inner loops.
- *
- * The amount of context is fixed at one row group just because that's a
- * convenient number for this controller to work with.  The existing
- * upsamplers really only need one sample row of context.  An upsampler
- * supporting arbitrary output rescaling might wish for more than one row
- * group of context when shrinking the image; tough, we don't handle that.
- * (This is justified by the assumption that downsizing will be handled mostly
- * by adjusting the DCT_scaled_size values, so that the actual scale factor at
- * the upsample step needn't be much less than one.)
- *
- * To provide the desired context, we have to retain the last two row groups
- * of one iMCU row while reading in the next iMCU row.  (The last row group
- * can't be processed until we have another row group for its below-context,
- * and so we have to save the next-to-last group too for its above-context.)
- * We could do this most simply by copying data around in our buffer, but
- * that'd be very slow.  We can avoid copying any data by creating a rather
- * strange pointer structure.  Here's how it works.  We allocate a workspace
- * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number
- * of row groups per iMCU row).  We create two sets of redundant pointers to
- * the workspace.  Labeling the physical row groups 0 to M+1, the synthesized
- * pointer lists look like this:
- *                   M+1                          M-1
- * master pointer --> 0         master pointer --> 0
- *                    1                            1
- *                   ...                          ...
- *                   M-3                          M-3
- *                   M-2                           M
- *                   M-1                          M+1
- *                    M                           M-2
- *                   M+1                          M-1
- *                    0                            0
- * We read alternate iMCU rows using each master pointer; thus the last two
- * row groups of the previous iMCU row remain un-overwritten in the workspace.
- * The pointer lists are set up so that the required context rows appear to
- * be adjacent to the proper places when we pass the pointer lists to the
- * upsampler.
- *
- * The above pictures describe the normal state of the pointer lists.
- * At top and bottom of the image, we diddle the pointer lists to duplicate
- * the first or last sample row as necessary (this is cheaper than copying
- * sample rows around).
- *
- * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1.  In that
- * situation each iMCU row provides only one row group so the buffering logic
- * must be different (eg, we must read two iMCU rows before we can emit the
- * first row group).  For now, we simply do not support providing context
- * rows when min_DCT_scaled_size is 1.  That combination seems unlikely to
- * be worth providing --- if someone wants a 1/8th-size preview, they probably
- * want it quick and dirty, so a context-free upsampler is sufficient.

- *
- * Exit: if return TRUE, have read and processed any parameters, and have
- *   updated the restart point to point after the parameters.
- *   If return FALSE, was forced to suspend before reaching end of
- *   marker parameters; restart point has not been moved.  Same routine
- *   will be called again after application supplies more input data.
- *
- * This approach to suspension assumes that all of a marker's parameters
- * can fit into a single input bufferload.  This should hold for "normal"
- * markers.  Some COM/APPn markers might have large parameter segments
- * that might not fit.  If we are simply dropping such a marker, we use
- * skip_input_data to get past it, and thereby put the problem on the
- * source manager's shoulders.  If we are saving the marker's contents
- * into memory, we use a slightly different convention: when forced to
- * suspend, the marker processor updates the restart point to the end of
- * what it's consumed (ie, the end of the buffer) before returning FALSE.
- * On resumption, cinfo->unread_marker still contains the marker code,
- * but the data source will point to the next chunk of marker data.
- * The marker processor must retain internal state to deal with this.
- *
- * Note that we don't bother to avoid duplicate trace messages if a
- * suspension occurs within marker parameters.  Other side effects
- * require more care.

- * which permits a more intelligent recovery strategy; such managers would
- * presumably supply their own resync method.
- *
- * read_restart_marker calls resync_to_restart if it finds a marker other than
- * the restart marker it was expecting.  (This code is *not* used unless
- * a nonzero restart interval has been declared.)  cinfo->unread_marker is
- * the marker code actually found (might be anything, except 0 or FF).
- * The desired restart marker number (0..7) is passed as a parameter.
- * This routine is supposed to apply whatever error recovery strategy seems
- * appropriate in order to position the input stream to the next data segment.
- * Note that cinfo->unread_marker is treated as a marker appearing before
- * the current data-source input point; usually it should be reset to zero
- * before returning.
- * Returns FALSE if suspension is required.
- *
- * This implementation is substantially constrained by wanting to treat the
- * input as a data stream; this means we can't back up.  Therefore, we have
- * only the following actions to work with:
- *   1. Simply discard the marker and let the entropy decoder resume at next
- *      byte of file.
- *   2. Read forward until we find another marker, discarding intervening
- *      data.  (In theory we could look ahead within the current bufferload,
- *      without having to discard data if we don't find the desired marker.
- *      This idea is not implemented here, in part because it makes behavior
- *      dependent on buffer size and chance buffer-boundary positions.)
- *   3. Leave the marker unread (by failing to zero cinfo->unread_marker).
- *      This will cause the entropy decoder to process an empty data segment,
- *      inserting dummy zeroes, and then we will reprocess the marker.
- *
- * #2 is appropriate if we think the desired marker lies ahead, while #3 is
- * appropriate if the found marker is a future restart marker (indicating
- * that we have missed the desired restart marker, probably because it got
- * corrupted).
- * We apply #2 or #3 if the found marker is a restart marker no more than
- * two counts behind or ahead of the expected one.  We also apply #2 if the
- * found marker is not a legal JPEG marker code (it's certainly bogus data).
- * If the found marker is a restart marker more than 2 counts away, we do #1
- * (too much risk that the marker is erroneous; with luck we will be able to
- * resync at some future point).
- * For any valid non-restart JPEG marker, we apply #3.  This keeps us from
- * overrunning the end of a scan.  An implementation limited to single-scan
- * files might find it better to apply #2 for markers other than EOI, since
- * any other marker would have to be bogus data in that case.

- * Several decompression processes need to range-limit values to the range
- * 0..MAXJSAMPLE; the input value may fall somewhat outside this range
- * due to noise introduced by quantization, roundoff error, etc.  These
- * processes are inner loops and need to be as fast as possible.  On most
- * machines, particularly CPUs with pipelines or instruction prefetch,
- * a (subscript-check-less) C table lookup
- *              x = sample_range_limit[x];
- * is faster than explicit tests
- *              if (x < 0)  x = 0;
- *              else if (x > MAXJSAMPLE)  x = MAXJSAMPLE;
- * These processes all use a common table prepared by the routine below.
- *
- * For most steps we can mathematically guarantee that the initial value
- * of x is within MAXJSAMPLE+1 of the legal range, so a table running from
- * -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient.  But for the initial
- * limiting step (just after the IDCT), a wildly out-of-range value is
- * possible if the input data is corrupt.  To avoid any chance of indexing
- * off the end of memory and getting a bad-pointer trap, we perform the
- * post-IDCT limiting thus:
- *              x = range_limit[x & MASK];
- * where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
- * samples.  Under normal circumstances this is more than enough range and
- * a correct output will be generated; with bogus input data the mask will
- * cause wraparound, and we will safely generate a bogus-but-in-range output.
- * For the post-IDCT step, we want to convert the data from signed to unsigned
- * representation by adding CENTERJSAMPLE at the same time that we limit it.
- * So the post-IDCT limiting table ends up looking like this:
- *   CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
- *   MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
- *   0          (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
- *   0,1,...,CENTERJSAMPLE-1
- * Negative inputs select values from the upper half of the table after
- * masking.
- *
- * We can save some space by overlapping the start of the post-IDCT table
- * with the simpler range limiting table.  The post-IDCT table begins at
- * sample_range_limit + CENTERJSAMPLE.
- *
- * Note that the table is allocated in near data space on PCs; it's small
- * enough and used often enough to justify this.

- * This file is part of the Independent JPEG Group's software.

- * This file contains code for merged upsampling/color conversion.
- *
- * This file combines functions from jdsample.c and jdcolor.c;
- * read those files first to understand what's going on.
- *
- * When the chroma components are to be upsampled by simple replication
- * (ie, box filtering), we can save some work in color conversion by
- * calculating all the output pixels corresponding to a pair of chroma
- * samples at one time.  In the conversion equations
- *      R = Y           + K1 * Cr
- *      G = Y + K2 * Cb + K3 * Cr
- *      B = Y + K4 * Cb
- * only the Y term varies among the group of pixels corresponding to a pair
- * of chroma samples, so the rest of the terms can be calculated just once.
- * At typical sampling ratios, this eliminates half or three-quarters of the
- * multiplications needed for color conversion.
- *
- * This file currently provides implementations for the following cases:
- *      YCbCr => RGB color conversion only.
- *      Sampling ratios of 2h1v or 2h2v.
- *      No scaling needed at upsample time.
- *      Corner-aligned (non-CCIR601) sampling alignment.
- * Other special cases could be added, but in most applications these are
- * the only common cases.  (For uncommon cases we fall back on the more
- * general code in jdsample.c and jdcolor.c.)

- * This implementation should be more accurate than either of the integer

- * The poop on this scaling stuff is as follows:
- *
- * Each 1-D DCT step produces outputs which are a factor of sqrt(N)
- * larger than the true DCT outputs.  The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm.  The advantage of
- * this arrangement is that we save two multiplications per 1-D DCT,
- * because the y0 and y4 outputs need not be divided by sqrt(N).
- * In the IJG code, this factor of 8 is removed by the quantization step
- * (in jcdctmgr.c), NOT in this module.
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic.  We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants).  After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output.  This division can be done
- * cheaply as a right shift of CONST_BITS bits.  We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision.  These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling.  (For 12-bit sample data, the intermediate
- * array is INT32 anyway.)
- *
- * To avoid overflow of the 32-bit intermediate results in pass 2, we must

- * Copyright (C) 1994-1998, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a floating-point implementation of the
- * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
- * must also perform dequantization of the input coefficients.
- *
- * This implementation should be more accurate than either of the integer
- * IDCT implementations.  However, it may not give the same results on all
- * machines because of differences in roundoff behavior.  Speed will depend
- * on the hardware's floating point capacity.
- *
- * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
- * on each row (or vice versa, but it's more convenient to emit a row at
- * a time).  Direct algorithms are also available, but they are much more
- * complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README).  The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs.  These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with a fixed-point
- * implementation, accuracy is lost due to imprecise representation of the
- * scaled quantization values.  However, that problem does not arise if
- * we use floating point arithmetic.

- * Copyright (C) 1994-1998, Thomas G. Lane.
- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a fast, not so accurate integer implementation of the
- * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
- * must also perform dequantization of the input coefficients.
- *
- * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
- * on each row (or vice versa, but it's more convenient to emit a row at
- * a time).  Direct algorithms are also available, but they are much more
- * complex and seem not to be any faster when reduced to code.
- *
- * This implementation is based on Arai, Agui, and Nakajima's algorithm for
- * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
- * Japanese, but the algorithm is described in the Pennebaker & Mitchell
- * JPEG textbook (see REFERENCES section in file README).  The following code
- * is based directly on figure 4-8 in P&M.
- * While an 8-point DCT cannot be done in less than 11 multiplies, it is
- * possible to arrange the computation so that many of the multiplies are
- * simple scalings of the final outputs.  These multiplies can then be
- * folded into the multiplications or divisions by the JPEG quantization
- * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
- * to be done in the DCT itself.
- * The primary disadvantage of this method is that with fixed-point math,
- * accuracy is lost due to imprecise representation of the scaled
- * quantization values.  The smaller the quantization table entry, the less
- * precise the scaled value, so this implementation does worse with high-
- * quality-setting files than with low-quality ones.

- * (right shift) multiplication products as soon as they are formed,
- * rather than carrying additional fractional bits into subsequent additions.
- * This compromises accuracy slightly, but it lets us save a few shifts.
- * More importantly, 16-bit arithmetic is then adequate (for 8-bit samples)
- * everywhere except in the multiplications proper; this saves a good deal
- * of work on 16-bit-int machines.
- *
- * The dequantized coefficients are not integers because the AA&N scaling
- * factors have been incorporated.  We represent them scaled up by PASS1_BITS,
- * so that the first and second IDCT rounds have the same input scaling.
- * For 8-bit JSAMPLEs, we choose IFAST_SCALE_BITS = PASS1_BITS so as to
- * avoid a descaling shift; this compromises accuracy rather drastically
- * for small quantization table entries, but it saves a lot of shifts.
- * For 12-bit JSAMPLEs, there's no hope of using 16x16 multiplies anyway,
- * so we use a much larger scaling factor to preserve accuracy.
- *
- * A final compromise is to represent the multiplicative constants to only
- * 8 fractional bits, rather than 13.  This saves some shifting work on some
- * machines, and may also reduce the cost of multiplication (since there
- * are fewer one-bits in the constants).

- * Each 1-D IDCT step produces outputs which are a factor of sqrt(N)
- * larger than the true IDCT outputs.  The final outputs are therefore
- * a factor of N larger than desired; since N=8 this can be cured by
- * a simple right shift at the end of the algorithm.  The advantage of
- * this arrangement is that we save two multiplications per 1-D IDCT,
- * because the y0 and y4 inputs need not be divided by sqrt(N).
- *
- * We have to do addition and subtraction of the integer inputs, which
- * is no problem, and multiplication by fractional constants, which is
- * a problem to do in integer arithmetic.  We multiply all the constants
- * by CONST_SCALE and convert them to integer constants (thus retaining
- * CONST_BITS bits of precision in the constants).  After doing a
- * multiplication we have to divide the product by CONST_SCALE, with proper
- * rounding, to produce the correct output.  This division can be done
- * cheaply as a right shift of CONST_BITS bits.  We postpone shifting
- * as long as possible so that partial sums can be added together with
- * full fractional precision.
- *
- * The outputs of the first pass are scaled up by PASS1_BITS bits so that
- * they are represented to better-than-integral precision.  These outputs
- * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
- * with the recommended scaling.  (To scale up 12-bit sample data further, an
- * intermediate INT32 array would be needed.)
- *
- * To avoid overflow of the 32-bit intermediate results in pass 2, we must
- * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis
- * shows that the values given below are the most effective.

- * with an 8-to-4 step that produces the four averages of two adjacent outputs
- * (or an 8-to-2 step producing two averages of four outputs, for 2x2 output).
- * These steps were derived by computing the corresponding values at the end
- * of the normal LL&M code, then simplifying as much as possible.

- * This file contains the JPEG system-independent memory management
- * routines.  This code is usable across a wide variety of machines; most
- * of the system dependencies have been isolated in a separate file.
- * The major functions provided here are:
- *   * pool-based allocation and freeing of memory;
- *   * policy decisions about how to divide available memory among the
- *     virtual arrays;
- *   * control logic for swapping virtual arrays between main memory and
- *     backing storage.
- * The separate system-dependent file provides the actual backing-storage
- * access code, and it contains the policy decision about how much total
- * main memory to use.
- * This file is system-dependent in the sense that some of its functions
- * are unnecessary in some systems.  For example, if there is enough virtual
- * memory so that backing storage will never be used, much of the virtual
- * array control logic could be removed.  (Of course, if you have that much
- * memory then you shouldn't care about a little bit of unused code...)

- * By default, we define ALIGN_TYPE as double.  This is necessary on some
- * workstations (where doubles really do need 8-byte alignment) and will work
- * fine on nearly everything.  If your machine has lesser alignment needs,
- * you can save a few bytes by making ALIGN_TYPE smaller.
- * The only place I know of where this will NOT work is certain Macintosh
- * 680x0 compilers that define double as a 10-byte IEEE extended float.

- * About virtual array management:

- * memory (as high as is possible given the desired memory limit), plus a
- * backing file that holds the rest of the array.
- *
- * The request_virt_array routines are told the total size of the image and
- * the maximum number of rows that will be accessed at once.  The in-memory
- * buffer must be at least as large as the maxaccess value.
- *
- * The request routines create control blocks but not the in-memory buffers.
- * That is postponed until realize_virt_arrays is called.  At that time the
- * total amount of space needed is known (approximately, anyway), so free
- * memory can be divided up fairly.
- *
- * The access_virt_array routines are responsible for making a specific strip
- * area accessible (after reading or writing the backing file, if necessary).
- * Note that the access routines are told whether the caller intends to modify
- * the accessed strip; during a read-only pass this saves having to rewrite
- * data to disk.  The access routines are also responsible for pre-zeroing
- * any newly accessed rows, if pre-zeroing was requested.
- *
- * In current usage, the access requests are usually for nonoverlapping
- * strips; that is, successive access start_row numbers differ by exactly
- * num_rows = maxaccess.  This means we can get good performance with simple
- * buffer dump/reload logic, by making the in-memory buffer be a multiple
- * of the access height; then there will never be accesses across bufferload
- * boundaries.  The code will still work with overlapping access requests,
- * but it doesn't handle bufferload overlaps very efficiently.

-/*
- * The main purpose of 1-pass quantization is to provide a fast, if not very
- * high quality, colormapped output capability.  A 2-pass quantizer usually
- * gives better visual quality; however, for quantized grayscale output this
- * quantizer is perfectly adequate.  Dithering is highly recommended with this
- * quantizer, though you can turn it off if you really want to.
- *
- * In 1-pass quantization the colormap must be chosen in advance of seeing the
- * image.  We use a map consisting of all combinations of Ncolors[i] color
- * values for the i'th component.  The Ncolors[] values are chosen so that
- * their product, the total number of colors, is no more than that requested.
- * (In most cases, the product will be somewhat less.)
- *
- * Since the colormap is orthogonal, the representative value for each color
- * component can be determined without considering the other components;
- * then these indexes can be combined into a colormap index by a standard
- * N-dimensional-array-subscript calculation.  Most of the arithmetic involved
- * can be precalculated and stored in the lookup table colorindex[].
- * colorindex[i][j] maps pixel value j in component i to the nearest
- * representative value (grid plane) for that component; this index is
- * multiplied by the array stride for component i, so that the
- * index of the colormap entry closest to a given pixel value is just
- *    sum( colorindex[component-number][pixel-component-value] )
- * Aside from being fast, this scheme allows for variable spacing between
- * representative values with no additional lookup cost.
- *
- * If gamma correction has been applied in color conversion, it might be wise
- * to adjust the color grid spacing so that the representative colors are
- * equidistant in linear space.  At this writing, gamma correction is not
- * implemented by jdcolor, so nothing is done here.

-
-/* Declarations for ordered dithering.
- *
- * We use a standard 16x16 ordered dither array.  The basic concept of ordered
- * dithering is described in many references, for instance Dale Schumacher's
- * chapter II.2 of Graphics Gems II (James Arvo, ed. Academic Press, 1991).
- * In place of Schumacher's comparisons against a "threshold" value, we add a
- * "dither" value to the input pixel and then round the result to the nearest
- * output value.  The dither value is equivalent to (0.5 - threshold) times
- * the distance between output values.  For ordered dithering, we assume that
- * the output colors are equally spaced; if not, results will probably be
- * worse, since the dither may be too much or too little at a given point.
- *
- * The normal calculation would be to form pixel value + dither, range-limit
- * this to 0..MAXJSAMPLE, and then index into the colorindex table as usual.
- * We can skip the separate range-limiting step by extending the colorindex
- * table in both directions.

- * This module implements the well-known Heckbert paradigm for color
- * quantization.  Most of the ideas used here can be traced back to
- * Heckbert's seminal paper
- *   Heckbert, Paul.  "Color Image Quantization for Frame Buffer Display",
- *   Proc. SIGGRAPH '82, Computer Graphics v.16 #3 (July 1982), pp 297-304.
- *
- * In the first pass over the image, we accumulate a histogram showing the
- * usage count of each possible color.  To keep the histogram to a reasonable
- * size, we reduce the precision of the input; typical practice is to retain
- * 5 or 6 bits per color, so that 8 or 4 different input values are counted
- * in the same histogram cell.
- *
- * Next, the color-selection step begins with a box representing the whole
- * color space, and repeatedly splits the "largest" remaining box until we
- * have as many boxes as desired colors.  Then the mean color in each
- * remaining box becomes one of the possible output colors.
- *
- * The second pass over the image maps each input pixel to the closest output
- * color (optionally after applying a Floyd-Steinberg dithering correction).
- * This mapping is logically trivial, but making it go fast enough requires
- * considerable care.
- *
- * Heckbert-style quantizers vary a good deal in their policies for choosing
- * the "largest" box and deciding where to cut it.  The particular policies
- * used here have proved out well in experimental comparisons, but better ones
- * may yet be found.
- *
- * In earlier versions of the IJG code, this module quantized in YCbCr color
- * space, processing the raw upsampled data without a color conversion step.
- * This allowed the color conversion math to be done only once per colormap
- * entry, not once per pixel.  However, that optimization precluded other
- * useful optimizations (such as merging color conversion with upsampling)
- * and it also interfered with desired capabilities such as quantizing to an
- * externally-supplied colormap.  We have therefore abandoned that approach.
- * The present code works in the post-conversion color space, typically RGB.
- *
- * To improve the visual quality of the results, we actually work in scaled
- * RGB space, giving G distances more weight than R, and R in turn more than
- * B.  To do everything in integer math, we must use integer scale factors.
- * The 2/3/1 scale factors used here correspond loosely to the relative
- * weights of the colors in the NTSC grayscale equation.
- * If you want to use this code to quantize a non-RGB color space, you'll
- * probably need to change these scale factors.

- * and B,G,R orders.  If you define some other weird order in jmorecfg.h,
- * you'll get compile errors until you extend this logic.  In that case

- * First we have the histogram data structure and routines for creating it.
- *
- * The number of bits of precision can be adjusted by changing these symbols.
- * We recommend keeping 6 bits for G and 5 each for R and B.
- * If you have plenty of memory and cycles, 6 bits all around gives marginally
- * better results; if you are short of memory, 5 bits all around will save
- * some space but degrade the results.
- * To maintain a fully accurate histogram, we'd need to allocate a "long"
- * (preferably unsigned long) for each cell.  In practice this is overkill;
- * we can get by with 16 bits per cell.  Few of the cell counts will overflow,
- * and clamping those that do overflow to the maximum value will give close-
- * enough results.  This reduces the recommended histogram size from 256Kb
- * to 128Kb, which is a useful savings on PC-class machines.
- * (In the second pass the histogram space is re-used for pixel mapping data;
- * in that capacity, each cell must be able to store zero to the number of
- * desired colors.  16 bits/cell is plenty for that too.)
- * Since the JPEG code is intended to run in small memory model on 80x86
- * machines, we can't just allocate the histogram in one chunk.  Instead
- * of a true 3-D array, we use a row of pointers to 2-D arrays.  Each
- * pointer corresponds to a C0 value (typically 2^5 = 32 pointers) and
- * each 2-D array has 2^6*2^5 = 2048 or 2^6*2^6 = 4096 entries.  Note that
- * on 80x86 machines, the pointer row is in near memory but the actual
- * arrays are in far memory (same arrangement as we use for image arrays).

- * These routines are concerned with the time-critical task of mapping input
- * colors to the nearest color in the selected colormap.
- *
- * We re-use the histogram space as an "inverse color map", essentially a
- * cache for the results of nearest-color searches.  All colors within a
- * histogram cell will be mapped to the same colormap entry, namely the one
- * closest to the cell's center.  This may not be quite the closest entry to
- * the actual input color, but it's almost as good.  A zero in the cache
- * indicates we haven't found the nearest color for that cell yet; the array
- * is cleared to zeroes before starting the mapping pass.  When we find the
- * nearest color for a cell, its colormap index plus one is recorded in the
- * cache for future use.  The pass2 scanning routines call fill_inverse_cmap
- * when they need to use an unfilled entry in the cache.
- *
- * Our method of efficiently finding nearest colors is based on the "locally
- * sorted search" idea described by Heckbert and on the incremental distance
- * calculation described by Spencer W. Thomas in chapter III.1 of Graphics
- * Gems II (James Arvo, ed.  Academic Press, 1991).  Thomas points out that
- * the distances from a given colormap entry to each cell of the histogram can
- * be computed quickly using an incremental method: the differences between
- * distances to adjacent cells themselves differ by a constant.  This allows a
- * fairly fast implementation of the "brute force" approach of computing the
- * distance from every colormap entry to every histogram cell.  Unfortunately,
- * it needs a work array to hold the best-distance-so-far for each histogram
- * cell (because the inner loop has to be over cells, not colormap entries).
- * The work array elements have to be INT32s, so the work array would need
- * 256Kb at our recommended precision.  This is not feasible in DOS machines.
- *
- * To get around these problems, we apply Thomas' method to compute the
- * nearest colors for only the cells within a small subbox of the histogram.
- * The work array need be only as big as the subbox, so the memory usage
- * problem is solved.  Furthermore, we need not fill subboxes that are never
- * referenced in pass2; many images use only part of the color gamut, so a
- * fair amount of work is saved.  An additional advantage of this
- * approach is that we can apply Heckbert's locality criterion to quickly
- * eliminate colormap entries that are far away from the subbox; typically
- * three-fourths of the colormap entries are rejected by Heckbert's criterion,
- * and we need not compute their distances to individual cells in the subbox.
- * The speed of this approach is heavily influenced by the subbox size: too
- * small means too much overhead, too big loses because Heckbert's criterion
- * can't eliminate as many colormap entries.  Empirically the best subbox
- * size seems to be about 1/512th of the histogram (1/8th in each direction).
- *
- * Thomas' article also describes a refined method which is asymptotically
- * faster than the brute-force method, but it is also far more complex and
- * cannot efficiently be applied to small subboxes.  It is therefore not
- * useful for programs intended to be portable to DOS machines.  On machines
- * with plenty of memory, filling the whole histogram in one shot with Thomas'
- * refined method might be faster than the present code --- but then again,
- * it might not be any faster, and it's certainly more complicated.

-
-OVERVIEW
-========
-
-This package contains C software to implement JPEG image compression and
-decompression.  JPEG (pronounced "jay-peg") is a standardized compression
-method for full-color and gray-scale images.  JPEG is intended for compressing
-"real-world" scenes; line drawings, cartoons and other non-realistic images
-are not its strong suit.  JPEG is lossy, meaning that the output image is not
-exactly identical to the input image.  Hence you must not use JPEG if you
-have to have identical output bits.  However, on typical photographic images,
-very good compression levels can be obtained with no visible change, and
-remarkably high compression levels are possible if you can tolerate a
-low-quality image.  For more details, see the references, or just experiment
-with various compression settings.
-
-This software implements JPEG baseline, extended-sequential, and progressive
-compression processes.  Provision is made for supporting all variants of these
-processes, although some uncommon parameter settings aren't implemented yet.
-For legal reasons, we are not distributing code for the arithmetic-coding
-variants of JPEG; see LEGAL ISSUES.  We have made no provision for supporting
-the hierarchical or lossless processes defined in the standard.
-
-We provide a set of library routines for reading and writing JPEG image files,
-plus two sample applications "cjpeg" and "djpeg", which use the library to
-perform conversion between JPEG and some other popular image file formats.
-The library is intended to be reused in other applications.
-
-In order to support file conversion and viewing software, we have included
-considerable functionality beyond the bare JPEG coding/decoding capability;
-for example, the color quantization modules are not strictly part of JPEG
-decoding, but they are essential for output to colormapped file formats or
-colormapped displays.  These extra functions can be compiled out of the
-library if not required for a particular application.  We have also included
-"jpegtran", a utility for lossless transcoding between different JPEG
-processes, and "rdjpgcom" and "wrjpgcom", two simple applications for
-inserting and extracting textual comments in JFIF files.
-
-The emphasis in designing this software has been on achieving portability and
-flexibility, while also making it fast enough to be useful.  In particular,
-the software is not intended to be read as a tutorial on JPEG.  (See the
-REFERENCES section for introductory material.)  Rather, it is intended to
-be reliable, portable, industrial-strength code.  We do not claim to have
-achieved that goal in every aspect of the software, but we strive for it.
-
-We welcome the use of this software as a component of commercial products.
-No royalty is required, but we do ask for an acknowledgement in product
-documentation, as described under LEGAL ISSUES.
-
-
-LEGAL ISSUES
-============
-
-In plain English:
-
-1. We don't promise that this software works.  (But if you find any bugs,
-   please let us know!)
-2. You can use this software for whatever you want.  You don't have to pay us.
-3. You may not pretend that you wrote this software.  If you use it in a
-   program, you must acknowledge somewhere in your documentation that
-   you've used the IJG code.
-
-In legalese:
-
-The authors make NO WARRANTY or representation, either express or implied,
-with respect to this software, its quality, accuracy, merchantability, or
-fitness for a particular purpose.  This software is provided "AS IS", and you,
-its user, assume the entire risk as to its quality and accuracy.
-
-This software is copyright (C) 1991-1998, Thomas G. Lane.
-All Rights Reserved except as specified below.
-
-Permission is hereby granted to use, copy, modify, and distribute this
-software (or portions thereof) for any purpose, without fee, subject to these
-conditions:
-(1) If any part of the source code for this software is distributed, then this
-README file must be included, with this copyright and no-warranty notice
-unaltered; and any additions, deletions, or changes to the original files
-must be clearly indicated in accompanying documentation.
-(2) If only executable code is distributed, then the accompanying
-documentation must state that "this software is based in part on the work of
-the Independent JPEG Group".
-(3) Permission for use of this software is granted only if the user accepts
-full responsibility for any undesirable consequences; the authors accept
-NO LIABILITY for damages of any kind.
-
-These conditions apply to any software derived from or based on the IJG code,
-not just to the unmodified library.  If you use our work, you ought to
-acknowledge us.
-
-Permission is NOT granted for the use of any IJG author's name or company name
-in advertising or publicity relating to this software or products derived from
-it.  This software may be referred to only as "the Independent JPEG Group's
-software".
-
-We specifically permit and encourage the use of this software as the basis of
-commercial products, provided that all warranty or liability claims are
-assumed by the product vendor.
-
-
-ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
-sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
-ansi2knr.c is NOT covered by the above copyright and conditions, but instead
-by the usual distribution terms of the Free Software Foundation; principally,
-that you must include source code if you redistribute it.  (See the file
-ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
-of any program generated from the IJG code, this does not limit you more than
-the foregoing paragraphs do.
-
-The Unix configuration script "configure" was produced with GNU Autoconf.
-It is copyright by the Free Software Foundation but is freely distributable.
-The same holds for its supporting scripts (config.guess, config.sub,
-ltconfig, ltmain.sh).  Another support script, install-sh, is copyright
-by M.I.T. but is also freely distributable.
-
-It appears that the arithmetic coding option of the JPEG spec is covered by
-patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
-legally be used without obtaining one or more licenses.  For this reason,
-support for arithmetic coding has been removed from the free JPEG software.
-(Since arithmetic coding provides only a marginal gain over the unpatented
-Huffman mode, it is unlikely that very many implementations will support it.)
-So far as we are aware, there are no patent restrictions on the remaining
-code.
-
-The IJG distribution formerly included code to read and write GIF files.
-To avoid entanglement with the Unisys LZW patent, GIF reading support has
-been removed altogether, and the GIF writer has been simplified to produce
-"uncompressed GIFs".  This technique does not use the LZW algorithm; the
-resulting GIF files are larger than usual, but are readable by all standard
-GIF decoders.
-
-We are required to state that
-    "The Graphics Interchange Format(c) is the Copyright property of
-    CompuServe Incorporated.  GIF(sm) is a Service Mark property of
-    CompuServe Incorporated."
-
-
-REFERENCES
-==========
-
-We highly recommend reading one or more of these references before trying to
-understand the innards of the JPEG software.
-
-The best short technical introduction to the JPEG compression algorithm is
-	Wallace, Gregory K.  "The JPEG Still Picture Compression Standard",
-	Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
-(Adjacent articles in that issue discuss MPEG motion picture compression,
-applications of JPEG, and related topics.)  If you don't have the CACM issue
-handy, a PostScript file containing a revised version of Wallace's article is
-available at ftp://ftp.uu.net/graphics/jpeg/wallace.ps.gz.  The file (actually
-a preprint for an article that appeared in IEEE Trans. Consumer Electronics)
-omits the sample images that appeared in CACM, but it includes corrections
-and some added material.  Note: the Wallace article is copyright ACM and IEEE,
-and it may not be used for commercial purposes.
-
-A somewhat less technical, more leisurely introduction to JPEG can be found in
-"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by
-M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1.  This book provides
-good explanations and example C code for a multitude of compression methods
-including JPEG.  It is an excellent source if you are comfortable reading C
-code but don't know much about data compression in general.  The book's JPEG
-sample code is far from industrial-strength, but when you are ready to look
-at a full implementation, you've got one here...
-
-The best full description of JPEG is the textbook "JPEG Still Image Data
-Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published
-by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1.  Price US$59.95, 638 pp.
-The book includes the complete text of the ISO JPEG standards (DIS 10918-1
-and draft DIS 10918-2).  This is by far the most complete exposition of JPEG
-in existence, and we highly recommend it.
-
-The JPEG standard itself is not available electronically; you must order a
-paper copy through ISO or ITU.  (Unless you feel a need to own a certified
-official copy, we recommend buying the Pennebaker and Mitchell book instead;
-it's much cheaper and includes a great deal of useful explanatory material.)
-In the USA, copies of the standard may be ordered from ANSI Sales at (212)
-642-4900, or from Global Engineering Documents at (800) 854-7179.  (ANSI
-doesn't take credit card orders, but Global does.)  It's not cheap: as of
-1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7%
-shipping/handling.  The standard is divided into two parts, Part 1 being the
-actual specification, while Part 2 covers compliance testing methods.  Part 1
-is titled "Digital Compression and Coding of Continuous-tone Still Images,
-Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS
-10918-1, ITU-T T.81.  Part 2 is titled "Digital Compression and Coding of
-Continuous-tone Still Images, Part 2: Compliance testing" and has document
-numbers ISO/IEC IS 10918-2, ITU-T T.83.
-
-Some extensions to the original JPEG standard are defined in JPEG Part 3,
-a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84.  IJG
-currently does not support any Part 3 extensions.
-
-The JPEG standard does not specify all details of an interchangeable file
-format.  For the omitted details we follow the "JFIF" conventions, revision
-1.02.  A copy of the JFIF spec is available from:
-	Literature Department
-	C-Cube Microsystems, Inc.
-	1778 McCarthy Blvd.
-	Milpitas, CA 95035
-	phone (408) 944-6300,  fax (408) 944-6314
-A PostScript version of this document is available by FTP at
-ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz.  There is also a plain text
-version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing
-the figures.
-
-The TIFF 6.0 file format specification can be obtained by FTP from
-ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz.  The JPEG incorporation scheme
-found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.
-IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6).
-Instead, we recommend the JPEG design proposed by TIFF Technical Note #2
-(Compression tag 7).  Copies of this Note can be obtained from ftp.sgi.com or
-from ftp://ftp.uu.net/graphics/jpeg/.  It is expected that the next revision
-of the TIFF spec will replace the 6.0 JPEG design with the Note's design.
-Although IJG's own code does not support TIFF/JPEG, the free libtiff library
-uses our library to implement TIFF/JPEG per the Note.  libtiff is available
-from ftp://ftp.sgi.com/graphics/tiff/.

-ARCHIVE LOCATIONS
-=================
-
-The "official" archive site for this software is ftp.uu.net (Internet
-address 192.48.96.9).  The most recent released version can always be found
-there in directory graphics/jpeg.  This particular version will be archived
-as ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz.  If you don't have
-direct Internet access, UUNET's archives are also available via UUCP; contact
-help@uunet.uu.net for information on retrieving files that way.
-
-Numerous Internet sites maintain copies of the UUNET files.  However, only
-ftp.uu.net is guaranteed to have the latest official version.
-
-You can also obtain this software in DOS-compatible "zip" archive format from
-the SimTel archives (ftp://ftp.simtel.net/pub/simtelnet/msdos/graphics/), or
-on CompuServe in the Graphics Support forum (GO CIS:GRAPHSUP), library 12
-"JPEG Tools".  Again, these versions may sometimes lag behind the ftp.uu.net
-release.
-
-The JPEG FAQ (Frequently Asked Questions) article is a useful source of
-general information about JPEG.  It is updated constantly and therefore is
-not included in this distribution.  The FAQ is posted every two weeks to
-Usenet newsgroups comp.graphics.misc, news.answers, and other groups.
-It is available on the World Wide Web at http://www.faqs.org/faqs/jpeg-faq/
-and other news.answers archive sites, including the official news.answers

-RELATED SOFTWARE
-================
-
-Numerous viewing and image manipulation programs now support JPEG.  (Quite a
-few of them use this library to do so.)  The JPEG FAQ described above lists
-some of the more popular free and shareware viewers, and tells where to
-obtain them on Internet.
-
-If you are on a Unix machine, we highly recommend Jef Poskanzer's free
-PBMPLUS software, which provides many useful operations on PPM-format image
-files.  In particular, it can convert PPM images to and from a wide range of
-other formats, thus making cjpeg/djpeg considerably more useful.  The latest
-version is distributed by the NetPBM group, and is available from numerous
-sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/.
-Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is;
-you are likely to have difficulty making it work on any non-Unix machine.
-
-A different free JPEG implementation, written by the PVRG group at Stanford,
-is available from ftp://havefun.stanford.edu/pub/jpeg/.  This program
-is designed for research and experimentation rather than production use;
-it is slower, harder to use, and less portable than the IJG code, but it
-is easier to read and modify.  Also, the PVRG code supports lossless JPEG,
-which we do not.  (On the other hand, it doesn't do progressive JPEG.)
-
-
-FILE FORMAT WARS
-================
-
-Some JPEG programs produce files that are not compatible with our library.
-The root of the problem is that the ISO JPEG committee failed to specify a
-concrete file format.  Some vendors "filled in the blanks" on their own,
-creating proprietary formats that no one else could read.  (For example, none
-of the early commercial JPEG implementations for the Macintosh were able to
-exchange compressed files.)
-
-The file format we have adopted is called JFIF (see REFERENCES).  This format
-has been agreed to by a number of major commercial JPEG vendors, and it has
-become the de facto standard.  JFIF is a minimal or "low end" representation.
-We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
-Technical Note #2) for "high end" applications that need to record a lot of
-additional data about an image.  TIFF/JPEG is fairly new and not yet widely
-supported, unfortunately.
-
-The upcoming JPEG Part 3 standard defines a file format called SPIFF.
-SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
-be able to read the most common variant of SPIFF.  SPIFF has some technical
-advantages over JFIF, but its major claim to fame is simply that it is an
-official standard rather than an informal one.  At this point it is unclear
-whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
-standard.  IJG intends to support SPIFF once the standard is frozen, but we
-have not decided whether it should become our default output format or not.
-(In any case, our decoder will remain capable of reading JFIF indefinitely.)
-
-Various proprietary file formats incorporating JPEG compression also exist.
-We have little or no sympathy for the existence of these formats.  Indeed,
-one of the original reasons for developing this free software was to help
-force convergence on common, open format standards for JPEG files.  Don't
-use a proprietary file format!
-
-
-TO DO
-=====
-
-The major thrust for v7 will probably be improvement of visual quality.
-The current method for scaling the quantization tables is known not to be
-very good at low Q values.  We also intend to investigate block boundary
-smoothing, "poor man's variable quantization", and other means of improving
-quality-vs-file-size performance without sacrificing compatibility.
-
-In future versions, we are considering supporting some of the upcoming JPEG
-Part 3 extensions --- principally, variable quantization and the SPIFF file
-format.
-
-As always, speeding things up is of great interest.
-
-Please send bug reports, offers of help, etc. to jpeg-info@uunet.uu.net.
