BGR

BGR macros are used to swap red and blue in color.

COLORREF BGR(COLORREF color);

Parameters

color

Needs swap colors in red and blue.

Return Value

Returns the color after swapping red and blue.

Remarks

Colors are represented in memory as 0xbbggrr (bb-blue, gg-green, rr-red), but the color in the memory is 0xrrggbb. Note that the red and blue of the two are the opposite. When directly manipulating the memory, the red and blue parts of the color can be exchanged through the BGR macro.
