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
