Fabian Giesen 0fbbda56fa stb_image: Account for tRNS chunk in non-paletted images. 
So we report channels_in_file correctly.

Fixes #329.

Fabian Giesen 49c7f1b397 stb_image: Optimise vertical flip. 
This incorporates #462, but also factors everything into one
function that is shared between 8-bit integer, 16-bit integer, and
float pixels (vertical flip operates on rows of bytes and doesn't
really care), and finally always uses a 2k on-stack buffer without
dynamic memory allocation, doing multiple memcpys per row if
necessary. Not only does this remove an out-of-memory failure mode,
it is also preferable for large images, since it's more
L1-cache-firendly this way.

Fixes #462.

Fabian Giesen 25a2596b2f stb_image: Fix rounding during unpremultiply. 
This is the same method as in pull request #455, but using integer
arithmetic instead of converting to float.

Fixes #455.

Fabian Giesen cc7f1d1e6d stb_image: Documentation fixes. 
req_comp is now desired_channels and *comp is *channels_in_file.

Fixes issue #466.

Fabian Giesen 0674660451 stb_image: Relax raw_len validation for non-interlaced PNGs. 
We used to require exact match between img_len and raw_len for
non-interlaced PNGs, but the PNG in issue #276 has extra bytes
(all zeros) at the end of the compressed DEFLATE stream.

The PNG spec doesn't have anything to say about it (that I
can tell), and if libpng accepts this, who are we to judge.

Fixes issue #276.

PopPoLoPoPpo 9bcda8bb1c Add stbi_load_16() variants to load from memory or callbacks 2017-05-05 00:39:08 +02:00
Jean-Sebastien Bevilacqua d8796f05bf Robustify stbi__sse2_available in stb_image.h 
Function `stbi__sse2_available` takes no argument,
we should be explicit by passing `void` as argument.
It will remove warnings from 'some' compilers.

Fabian Giesen 22c72a069c stb_image: Support optional args consistently. 
My guideline for the rules is the PNG loader (which I consider
"canonical"). In the _load functions, x and y are required but
comp is optional; in the _info functions, all three are optional.

Fixes issue #411 (and other related, unreported issues).

Fabian Giesen 3e17544873 stb_image: Give up trying to runtime-detect SSE2 on GCC. 
We tried but it was nothing but trouble. New rule: with
GCC/Clang, if you're compiling with -msse2, you get always-on
SSE2 code, otherwise you don't get any. Trying to ship
anything with proper runtime dispatch requires both working
around certain bugs and some fiddling with build settings,
which runs contrary to the intent of a one-file library,
so bail on it entirely.

Fixes issue #280.
