Field Documentation

GLint gl_texture_format::MesaFormat

One of the MESA_FORMAT_* values.

GLenum gl_texture_format::BaseFormat

Either GL_RGB, GL_RGBA, GL_ALPHA, GL_LUMINANCE, GL_LUMINANCE_ALPHA, GL_INTENSITY, GL_COLOR_INDEX or GL_DEPTH_COMPONENT.

GLenum gl_texture_format::DataType

GL_FLOAT or GL_UNSIGNED_NORMALIZED_ARB.

GLubyte gl_texture_format::RedBits

Bits per texel component.

These are just rough approximations for compressed texture formats.
