SDL_CreateSurfaceFrom

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

Header File

Defined in SDL_surface.h, but apps should use #include <SDL3/SDL.h>

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

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

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.
