# SDL_SaveBMP

Save a surface to a file.

## Header File

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

## Syntax

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

```

## Function Parameters

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

## Return Value

Returns 0 on success or a negative error code 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.

## Version

This function is available since SDL 3.0.0.
