Subject: [PATCH spice-common] canvas-base: Fix width computation for palette
|
|
|
71360e |
images
|
|

|
|
|
71360e |
Palette images are encoded with a slightly larger pixel than
|
|
|
71360e |
width. This cause a wrong calculation of stride_encoded value
|
|
|
71360e |
which cause a wrong stride adjustment.
|
|
|
71360e |
|
|
|

This fix bug https://bugzilla.redhat.com/show_bug.cgi?id=1508847.
