Allocate a new RGB surface with a specific pixel format and existing pixel data.
Defined in <SDL3/SDL_surface.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.
