SDL_ConvertSurface - Man Page

Defined in SDL3/SDL_surface.h

#include "SDL3/SDL.h"

SDL_Surface * SDL_ConvertSurface(SDL_Surface *surface, SDL_PixelFormat format);

This function is used to optimize images for faster repeat blitting. This is accomplished by converting the original and storing the result as a new surface. The new, optimized surface can then be used as the source for future blits, making them faster.

If you are converting to an indexed surface and want to map colors to a palette, you can use

SDL_ConvertSurfaceAndColorspace () instead.

If the original surface has alternate images, the new surface will have a reference to them as well.

surface

the existing SDL_Surface
structure to convert.

format

the new pixel format.

( SDL_Surface
*) Returns the new SDL_Surface

structure that is created or NULL on failure; call

SDL_GetError () for more information.

This function is available since SDL 3.2.0.
