Okay, a few more questions:
|
|
|
642c2b |
|
|
|
642c2b |
* If Fedora decides to simply reproduce the quoted statement:
|
|
|
642c2b |
"Uses Jimenez's MLAA. Copyright (C) 2010 by Jorge Jimenez, Belen Masia,
|
|
|
642c2b |
Jose I. Echevarria, Fernando Navarro and Diego Gutierrez."
|
|
|
642c2b |
|
|
|
642c2b |
Specifically, if this is done as part of documentation included with
|
|
|
642c2b |
Mesa, is that sufficient to meet clause 2 even if the Mesa config option
|
|
|
642c2b |
is not set as described in your exception?
|
|
|
642c2b |
|
|
|
642c2b |
* Currently, the Mesa config option for MLAA says: "Morphological
|
|
|
642c2b |
anti-aliasing based on Jimenez\' MLAA. 0 to disable, 8 for default
|
|
|
642c2b |
quality". Is this in compliance with your exception?
|
|
|
642c2b |
|
|
|
642c2b |
Thanks again,

Hi Tom,
|
|
|
642c2b |
|
|
|
642c2b |
What we meant with that is that we made an exception for clause 2.
|
|
|
642c2b |
Instead of clause 2, in the case of the Mesa project, you have to name
|
|
|
642c2b |
the technique Jimenez's MLAA in the config options of Mesa. We did that
|
|
|
642c2b |
just to allow them to solve license issues. This exception should be for
|
|
|
642c2b |
the Mesa project, and any project using Mesa, like Fedora.
|
|
|
642c2b |
|
|
|
642c2b |
We want to widespread usage of our MLAA, so we want to avoid any kind of
|
|
|
642c2b |
license complications. Hope current one is good for Fedora, if not
|
|
|
642c2b |
please tell, and we'll see what we can do!
|
|
|
642c2b |

Jorge,
|
|
|
642c2b |
|
|
|
642c2b |
Thanks for all of your fantastic graphics work! I have been auditing
|
|
|
642c2b |
Fedora (a popular distribution of Linux) for license compliance and I
|
|
|
642c2b |
came across your MLAA code in Mesa.
|
|
|
642c2b |
|
|
|
642c2b |
The license says:
|
|
|
642c2b |
|
|
|
642c2b |
* 2. Redistributions in binary form must reproduce the following
|
|
|
642c2b |
statement:
|
|
|
642c2b |
*
|
|
|
642c2b |
* "Uses Jimenez's MLAA. Copyright (C) 2010 by Jorge Jimenez, Belen Masia,
|
|
|
642c2b |
* Jose I. Echevarria, Fernando Navarro and Diego Gutierrez."
|
|
|
642c2b |
*
|
|
|
642c2b |
* Only for use in the Mesa project, this point 2 is filled by naming the
|
|
|
642c2b |
* technique Jimenez's MLAA in the Mesa config options.
|
|
|
642c2b |
|
|
|
642c2b |
That wording is unclear. When you say "Only for use in the Mesa
|
|
|
642c2b |
project...", it seems like you could either be saying:
|
|
|
642c2b |
|
|
|
642c2b |
- This code may only be used as part of Mesa.
|
|
|
642c2b |
|
|
|
642c2b |
OR
|
|
|
642c2b |
|
|
|
642c2b |
- In Mesa, you can comply with clause 2 by simply selecting "Jimenez's
|
|
|
642c2b |
MLAA" in the Mesa config options.
|
|
|
642c2b |
|
|
|
642c2b |
*****
|
|
|
642c2b |
|
|
|
642c2b |
If the first item is true, then we may have to remove the MLAA code from
|
|
|
642c2b |
Fedora's copy of Mesa. However, looking at the license on your SMAA
|
|
|
642c2b |
code, I do not believe it to be the case. Please let me know either way!

Thanks in advance,
