Detailed Description
Implements an Image using OpenGL.
This class contains a texture handle bound to the data given to the constructor; it draws a textured Quad to the screen.
- See also:
- Image
- Note:
- Width and height are not limited to powers of two; non-power of two images will be converted internally.
- Todo:
- Check the correctness of the generateTexture function on big endian systems (ppc)
