# SDL_SaveBMP

Save a surface to a file in BMP format.

## Header File

Defined in [<SDL3/SDL_surface.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_surface.h)

## Syntax

```c
bool SDL_SaveBMP(SDL_Surface *surface, const char *file);
```

## Function Parameters

|                              |             |                                                                            |
| ---------------------------- | ----------- | -------------------------------------------------------------------------- |
| [SDL_Surface](SDL_Surface) * | **surface** | the [SDL_Surface](SDL_Surface) structure containing the image to be saved. |
| const char *                 | **file**    | a file to save to.                                                         |

## Return Value

(bool) Returns true on success or false on failure; call
[SDL_GetError](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.
