BrushCopy, CopyRect example
The following code illustrates the differences between CopyRect and BrushCopy. The bitmap graphic ‘TARTAN.BMP’ is loaded into Bitmap and displayed on the Canvas of Form1. BrushCopy replaces the color black in the graphic with the brush of the canvas, while CopyRect leaves the colors intact.
} 
var
  Bitmap: TBitmap;
  MyRect, MyOther: TRect;
begin
  MyRect := Rect(10,10,100,100);
  MyOther := Rect(10,111,100, 201);
  Bitmap := TBitmap.Create;
  Bitmap.LoadFromFile('c:\windows\tartan.bmp');
  Form1.Canvas.BrushCopy(MyRect, Bitmap, MyRect, clBlack);
  Form1.Canvas.CopyRect(MyOther,Bitmap.Canvas,MyRect);
  Bitmap.Free;
end;
