Sean Barrett 6ade66182c allow alpha channel to be channel #0 2014-08-11 02:34:50 -07:00
Sean Barrett f502cae91a rename everything to do with premultiplied alpha since the whole 
point is that this is for handling *non*-premultiplied alpha (since
correct handling of premultiplied alpha requires doing nothing)

Jean-Sbastien Guay ebc2d23d47 realized the 2 colorbytes case is impossible. 
also updated the comment at the top of the file to reflect stbi_write_tga's new capabilities.
 2014-08-09 09:16:57 -04:00
Jean-Sbastien Guay 26a71f67fe comment was wrong way around... code was right. 2014-08-09 01:08:43 -04:00
Jean-Sbastien Guay b8b364c301 stbi_write_tga can now write 1 and 2 channel (grayscale and grayscale-alpha) images. 2014-08-09 00:34:49 -04:00
Michał Cichoń 10def9b150 fix MSVC-ARM internal compiler error by wrapping malloc 
For some reason Microsoft CL compiler for ARM is unable to compile malloc when parameter is an expression. malloc(x * y) will cause internal compiler error, malloc(x) is however fine.

Ronny Chevalier 2119c17ae9 stb_vorbis: fix unused variables 
Conflicts:
	stb_vorbis.c
 2014-08-07 04:23:33 -07:00
Sean Barrett 260741ed33 vorbis warnings from ronny chevalier 
I manually made these changes because they
disabled some substantial amounts of code,
and I wanted to make sure this wasn't due to
original code having bugs or deviating from
the specification

Jorge Rodriguez e05ebdbf1e My guess is people who care about premultiply also care about color space. 2014-07-31 19:37:42 -07:00
Jorge Rodriguez d75488b0e8 Do the multiply inline, it should be a tad faster and not corrupt our data. 2014-07-31 19:00:48 -07:00
