Version 1.5.3beta09 [May 17, 2011]
|

Reversed earlier 1.5.3 change of transformation order; move png_expand_16 back.
|
||||
The change doesn't work because it requires 16 bit gamma tables when the code
|
||||
only generates 8 bit ones. This fails silently; the libpng code just doesn't
|
||||
do any gamma correction. Moving the tests back leaves the old, inaccurate, 8
|
||||
bit gamma calculations, but these are clearly better than none!
