sdlSaveBmp function

bool sdlSaveBmp(
  1. Pointer<SdlSurface> surface,
  2. String? file
)

Save a surface to a file.

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 file a file to save to. \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
