Simple OpenGL Image Library
A tiny c library for uploading images as
textures into OpenGL. Also saving and
loading of images is supported.
I'm using Sean's Tool Box image loader as a base:
http://www.nothings.org/
I'm upgrading it to load TGA and DDS files, and a direct
path for loading DDS files straight into OpenGL textures,
when applicable.
Image Formats:
- BMP load & save
- TGA load & save
- DDS load & save
- PNG load
- JPG load
OpenGL Texture Features:
- resample to power-of-two sizes
- MIPmap generation
- compressed texture S3TC formats (if supported)
- can pre-multiply alpha for you, for better compositing
- can flip image about the y-axis (except pre-compressed DDS files)
Thanks to:
* Sean Barret - for the awesome stb_image
* Dan Venkitachalam - for finding some non-compliant DDS files, and patching some explicit casts
* everybody at gamedev.net
