###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_GetMasksForPixelFormat Convert one of the enumerated pixel formats to a bpp value and RGBA masks. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_pixels.h) ## Syntax ```c SDL_bool SDL_GetMasksForPixelFormat(SDL_PixelFormat format, int *bpp, Uint32 *Rmask, Uint32 *Gmask, Uint32 *Bmask, Uint32 *Amask); ``` ## Function Parameters | | | | | ---------------------------------- | ---------- | ------------------------------------------------------- | | [SDL_PixelFormat](SDL_PixelFormat) | **format** | one of the [SDL_PixelFormat](SDL_PixelFormat) values. | | int * | **bpp** | a bits per pixel value; usually 15, 16, or 32. | | Uint32 * | **Rmask** | a pointer filled in with the red mask for the format. | | Uint32 * | **Gmask** | a pointer filled in with the green mask for the format. | | Uint32 * | **Bmask** | a pointer filled in with the blue mask for the format. | | Uint32 * | **Amask** | a pointer filled in with the alpha mask for the format. | ## Return Value ([SDL_bool](SDL_bool)) Returns [SDL_TRUE](SDL_TRUE) on success or [SDL_FALSE](SDL_FALSE) on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Thread Safety It is safe to call this function from any thread. ## Version This function is available since SDL 3.0.0. ## See Also - [SDL_GetPixelFormatForMasks](SDL_GetPixelFormatForMasks) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryPixels](CategoryPixels)
