NAME

SDL_GetRGBA- Get RGBA values from a pixel in the specified pixel format.

SYNOPSIS

#include

void SDL_GetRGBA(__Uint32 pixel, SDL_!PixelFormat

• fmt, Uint8 *r, Uint8 *g, Uint8 *b, Uint8
• a__);

DESCRIPTION

Get RGBA component values from a pixel stored in the specified pixel format.

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 [unrenderable node] not [0xf8, 0xfc, 0xf8).

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