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. Enumeration values: MESA_FORMAT_RGBA8888  MESA_FORMAT_RGBA8888_REV  MESA_FORMAT_ARGB8888  MESA_FORMAT_ARGB8888_REV  MESA_FORMAT_RGB888  MESA_FORMAT_BGR888  MESA_FORMAT_RGB565  MESA_FORMAT_RGB565_REV  MESA_FORMAT_ARGB4444  MESA_FORMAT_ARGB4444_REV  MESA_FORMAT_ARGB1555  MESA_FORMAT_ARGB1555_REV  MESA_FORMAT_AL88  MESA_FORMAT_AL88_REV  MESA_FORMAT_RGB332  MESA_FORMAT_A8  MESA_FORMAT_L8  MESA_FORMAT_I8  MESA_FORMAT_CI8  MESA_FORMAT_YCBCR  MESA_FORMAT_YCBCR_REV  MESA_FORMAT_RGB_FXT1  MESA_FORMAT_RGBA_FXT1  MESA_FORMAT_RGB_DXT1  MESA_FORMAT_RGBA_DXT1  MESA_FORMAT_RGBA_DXT3  MESA_FORMAT_RGBA_DXT5  MESA_FORMAT_RGBA  MESA_FORMAT_RGB  MESA_FORMAT_ALPHA  MESA_FORMAT_LUMINANCE  MESA_FORMAT_LUMINANCE_ALPHA  MESA_FORMAT_INTENSITY  MESA_FORMAT_DEPTH_COMPONENT_FLOAT32  Depth textures.

Function Documentation

const struct gl_texture_format* _mesa_choose_tex_format (  GLcontext *    ctx, GLint    internalFormat, GLenum    format, GLenum    type )

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.
