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

Header File

Defined in <SDL3/SDL_surface.h>


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

Function Parameters

int width the width of the surface.
int height the height of the surface.
SDL_PixelFormat format the SDL_PixelFormat for the new surface's pixel format.
void * pixels a pointer to existing pixel data.
int pitch the number of bytes between each row, including padding.

Return Value

(SDL_Surface *) 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.

Pitch is the offset in bytes from one row of pixels to the next, e.g. width*4 for SDL_PIXELFORMAT_RGBA8888.

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.
