SDL_CreateSurfaceFrom

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

#include <SDL3/SDL_surface.h>
SDL_Surface * SDL_CreateSurfaceFrom(int width, int height, SDL_PixelFormat format, void *pixels, int pitch);

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.

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

Returns the new SDL_Surface structure that is created or NULL on failure; call SDL_GetError() for more information.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
