sdlSaveBmpIo function surface

bool sdlSaveBmpIo(Pointer<SdlSurface> surface, Pointer<SdlIoStream> dst, bool closeio)

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

Surfaces with a 24-bit, 32-bit and paletted 8-bit format get saved in the BMP directly. Other RGB formats with 8-bit or higher get converted to a 24-bit surface or, if they have an alpha mask or a colorkey, to a 32-bit surface before they are saved. YUV and paletted 1-bit and 4-bit formats are not supported.

\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 3.2.0.
