SDL_SaveBMP_IO

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

Header File

Syntax

int SDL_SaveBMP_IO(SDL_Surface *surface, SDL_IOStream *dst, SDL_bool closeio);

Function Parameters

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

Return Value

Returns 0 on success or a negative error code 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.

Version

This function is available since SDL 3.0.0.
