Enumeration Type Documentation

enum _format

Mesa internal texture image formats.

All texture images are stored in one of these formats.

NOTE: when you add a new format, be sure to update the do_row() function in texstore.c used for auto mipmap generation.

Function Documentation

struct gl_texture_format* _mesa_choose_tex_format ( GLcontext *  ctx,
GLint  internalFormat,
GLenum  format,
GLenum  type 
) [read]

Choose an appropriate texture format given the format, type and internalFormat parameters passed to glTexImage().

Parameters:
ctx the GL context.
internalFormat user's prefered internal texture format.
format incoming image pixel format.
type incoming image data type.
Returns:
a pointer to a gl_texture_format object which describes the choosen texture format, or NULL on failure.
This is called via dd_function_table::ChooseTextureFormat. Hardware drivers will typically override this function with a specialized version.

void _mesa_format_to_type_and_comps ( const struct gl_texture_format *  format,
GLenum *  datatype,
GLuint *  comps 
)

Return datatype and number of components per texel for the given gl_texture_format.
