Description
Converts RGB values specified by R, G and B to a regular color value. The result can be split back into RGB values using ColorToRGB.
Example 1
begin WriteLn(RGBToColor(0, 0, 0)); WriteLn(RGBToColor(255, 0, 0)); WriteLn(RGBToColor(0, 255, 0)); WriteLn(RGBToColor(0, 0, 255)); WriteLn(RGBToColor(255, 255, 255)); end.
Output:
0 255 65280 16711680 16777215
Example 2
var c, r, g, b: Integer; begin c := RGBToColor(1, 25, 127); WriteLn(c); ColorToRGB(c, r, g, b); WriteLn(IntToStr(r) + ',' + IntToStr(g) + ',' + IntToStr(b)); end.
Output:
8329473 1,25,127
