imgSaveTypedIo function image

bool imgSaveTypedIo(Pointer<SdlSurface> surface, Pointer<SdlIoStream> dst, bool closeio, String? type,)

Save an SDL_Surface into formatted image data, via an SDL_IOStream.

If you just want to save to a filename, you can use IMG_Save() instead.

If closeio is true, dst will be closed before returning, whether this function succeeds or not.

For formats that accept a quality, a default quality of 90 will be used.

\param surface the SDL surface to save. \param dst the SDL_IOStream to save the image data to. \param closeio true to close/free the SDL_IOStream before returning, false to leave it open. \param type a filename extension that represent this data ("BMP", "GIF", "PNG", etc). \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL_image 3.4.0.
