Allocate a new surface with a specific pixel format and existing pixel data.
Defined in <SDL3/SDL_surface.h>
SDL_Surface * SDL_CreateSurfaceFrom(int width, int height, SDL_PixelFormat format, void *pixels, int pitch);| 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. |
(SDL_Surface *) Returns the new SDL_Surface structure that is created or NULL on failure; 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 3.1.3.
