sdlCreateSurfaceFrom function surface

Pointer<SdlSurface> sdlCreateSurfaceFrom(int width, int height, int format, Pointer<NativeType> pixels, int pitch,)

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

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.

\param width the width of the surface. \param height the height of the surface. \param format the SDL_PixelFormat for the new surface's pixel format. \param pixels a pointer to existing pixel data. \param pitch 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.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.2.0.
