C++ (Cpp) R_GetTextureParms Examples

Example #1

File: gl_decals.c Project: mittorn/xash3d

//-----------------------------------------------------------------------------
// find decal image and grab size from it
//-----------------------------------------------------------------------------
static void R_GetDecalDimensions( int texture, int *width, int *height )
{
	if( width ) *width = 1;	// to avoid divide by zero
	if( height ) *height = 1;

	R_GetTextureParms( width, height, texture );
}
