Allocate a new RGB surface with with a specific pixel format and existing pixel data.


SDL_Surface* SDL_CreateSurfaceFrom
    (void *pixels, int width, int height, int pitch, Uint32 format);

Function Parameters

pixels a pointer to existing pixel data
width the width of the surface
height the height of the surface
pitch the pitch of the surface in bytes
format the SDL_PixelFormatEnum for the new surface's pixel format.

Return Value

Returns the new SDL_Surface structure that is created or NULL if it fails; call SDL_GetError() for more information.


No copy is made of the pixel data. Pixel data is not managed automatically; you must free the surface before you free the pixel data.

You may pass NULL for pixels and 0 for pitch to create a surface that you will fill in with valid values later.


This function is available since SDL 3.0.0.
