# SDL_MasksToPixelFormatEnum

Convert a bpp value and RGBA masks to an enumerated pixel format.

## Header File

Defined in [SDL_pixels.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_pixels.h), but apps should _only_ `#include "SDL.h"`!

## Syntax

```c
Uint32 SDL_MasksToPixelFormatEnum(int bpp,
                                  Uint32 Rmask,
                                  Uint32 Gmask,
                                  Uint32 Bmask,
                                  Uint32 Amask);

```

|               |                                               |
| ------------- | --------------------------------------------- |
| **bpp**       | a bits per pixel value; usually 15, 16, or 32 |
| **Rmask**     | the red mask for the format                   |
| **Gmask**     | the green mask for the format                 |

| **Amask**     | the alpha mask for the format                 |

## Return Value

Returns one of the [SDL_PixelFormatEnum](SDL_PixelFormatEnum) values

the conversion wasn't possible.
