Subject: Bug 607242 - GIMP 2.7.0 fails to build against libpng 1.4.0
|
|
|
|
Use png_set_expand_gray_1_2_4_to_8() instead of the deprecated
|
|
png_set_gray_1_2_4_to_8() if libpng is at least 1.2.27 (which is in
|
|
debian stable), so plug-ins built against old versions contine to work
|
|
when libpng 1.4 gets installed.
