Craig Donner ee6978cb68 Slightly modify the public domain license to keep it in the public domain, but make it clear that even when dedications might not be recognized that the code is still usable. Given that this isn't dual-licensing under a different license, I'm hoping this will be acceptable. 2016-02-25 12:55:44 -08:00

Daniel Gibson 87a0396922 stb_image.h: 16 bit TGAs don't really have an alpha channel 
I claimed that if the most significant bit of a 16bit pixel is set,
it should be opaque (as is suggested by some sources on the internet),
but implemented the opposite.
If implemented "correctly", lots of 16bit TGAs become invisible.. so I
guess 16bit TGAs aren't really supposed to have an alpha-channel, or at
least most 16bit TGAs (despite having set an "alpha-bit" in the "image
descriptor byte") in the wild don't seem to work like that.

So just assume 16bit non-greyscale TGAs are always STBI_rgb without
an alpha channel.

Daniel Gibson d235049322 stb_image.h: Fix TGA colormap support 
* Calculate correct stb format (incl. proper 16bit support) also when
  using a colormap (palette)
* Create colormap with tga_comp, to correctly support 16bit RGB
  (instead of using tga_palette_bits/8 and just copying the data)
* For TGAs with colormap, the TGA bits per pixel field specifies the
  size of an index to the colormap - the "real" color depth
  of the image is saved in the color map specification's bits per pixel
  field. I think only 8 and 16bit indices make sense (16 should be
  supported, otherwise the colormap length could be u8 instead of u16),
  so I added support for both.
* Helper functions stbi__tga_get_comp() to calculate stb pixelformat and
  stbi__tga_read_rgb16() to read one 16bit pixel and convert it to
  24/32bit RGB(A) - for less duplicate code

Daniel Gibson 57409c3d15 stb_image.h: Improve stbi__tga_info() and stbi__tga_test() 
* for paletted images, .._info()'s comp should be based on the palette's
  bits per pixel, not the images bits per pixel (which describes the
  size of an index into the palette and is also checked now)
* make sure the color (map) type and the image type fields of the header
  are consistent (=> if TGA color type is 1 for paletted, the TGA image
  type must be 1 or 9)
* .._test() does some more checks and uses stbi__get16le() instead of
  stbi__get16be() - TGA is little endian.
* .._test() now always rewinds (sometimes it used to do only return 0;
  without rewinding)
* remove "error check" at the beginning of stbi__tga_load(), because
  all that is already tested in stbi__tga_test()

Daniel Gibson 7453e1bfa4 stb_image.h: Support 15/16bit per pixel RGB(A) TGAs 
stbi__tga_* assumed that 16bit TGAs were Grayscale + Alpha.
However, if the TGA imagetype is not one of the gray ones, it's 16Bit
RGB data, with 5 Bits per channel. If the TGA image descriptor field
has alpha bits (the 3 least significant ones) set, the pixel's most
significant bit is for alpha: 1 for opaque and 0 for translucent.
Furthermore people claim that TGAs can also pretend to have 15bpp,
which is the same as 16bpp but definitely without alpha.

So 15/16bpp TGAs are now decoded to STBI_rgb(_alpha).
