Changes since the last public release (1.4.0beta107):
|
|
|
|
version 1.4.1alpha01 [November 27, 2009]
|
|
Based on 1.4.0beta107
|
|
|
|
version 1.4.1alpha02 [December 4, 2009]
|
|
Restored premultiplied alpha feature from version 1.4.0beta105.
|
|
Added "double gamma" to parameters for png_set_premultiply_alpha().
|
|
Added "float postmultiply_gamma" member to the png_struct.
|
|
Moved PNG_DIVIDE_BY_255, PNG_8_BIT_PREMULTIPLY(), etc., from
|
|
png.h to pngpriv.h
|
|
Updated documentation about png_set_premultiply_alpha().
|
|
Always expand pixels to 16-bit samples when premultiplying.
|
|
In pngconf.h, require PNG_GAMMA_SUPPORTED to be defined when defining
|
|
PNG_READ_PREMULTIPLY_ALPHA_SUPPORTED
|
|
Eliminated PNG_DIVIDE_BY_255 and PNG_8_BIT_PREMULTIPLY macros
|
|
leaving only PNG_DIVIDE_BY_65535 and PNG_16_BIT_PREMULTIPLY
|
|
because we will always work with 16 bits.
