= SDL_GetRGBA =
Use this function to get RGBA values from a pixel in the specified format.

<<TableOfContents()>>

== Syntax ==
{{{#!highlight cpp
void SDL_GetRGBA(Uint32                 pixel,
                 const SDL_PixelFormat* format,
                 Uint8*                 r,
                 Uint8*                 g,
                 Uint8*                 b,
                 Uint8*                 a)
}}}

== Function Parameters ==
||'''pixel'''||a pixel value||
||'''format'''||an [[SDL_PixelFormat]] structure describing the format of the pixel||
||'''r'''||a pointer filled in with the red component||
||'''g'''||a pointer filled in with the green component||
||'''b'''||a pointer filled in with the blue component||
||'''a'''||a pointer filled in with the alpha component||

== Code Examples ==

== Remarks ==
This function uses the entire 8-bit [0..255] range when converting color components from pixel formats with less than 8-bits per RGB component (e.g., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).

If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque).
