sdlSavePngIo function surface

bool sdlSavePngIo(
  1. Pointer<SdlSurface> surface,
  2. Pointer<SdlIoStream> dst,
  3. bool closeio
)

Save a surface to a seekable SDL data stream in PNG format.

\param surface the SDL_Surface structure containing the image to be saved. \param dst a data stream to save to. \param closeio if true, calls SDL_CloseIO() on dst before returning, even in the case of an error. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function can be called on different threads with different surfaces.

\since This function is available since SDL 3.4.0.
