- * Return GLubyte values in the specified dest image format.
- * This is used by glDrawPixels and glTexImage?D().
- * \param ctx - the context

- *         dstFormat - format of destination color array
- *         dest - the destination color array

- *         srcPacking - pixel unpacking parameters
