SDL_SaveBMP_IO

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

Header File

Syntax

bool SDL_SaveBMP_IO(SDL_Surface *surface, SDL_IOStream *dst, bool closeio);

Function Parameters

SDL_Surface *	surface	the SDL_Surface structure containing the image to be saved.
SDL_IOStream *	dst	a data stream to save to.
bool	closeio	if true, calls SDL_CloseIO() on `dst` before returning, even in the case of an error.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.

Remarks

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.

Thread Safety

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

Version

This function is available since SDL 3.2.0.
