BrushCopy (Delphi)
Contents
Description
The following code illustrates the differences between CopyRect and BrushCopy. The bitmap graphic FACTORY.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.
Code
procedure TForm1.Button1Click(Sender: TObject);
var
Bitmap: TBitmap;
MyRect, MyOther: TRect;
begin
MyRect := Rect(10,10,150,150);
MyOther := Rect(10,161,150,301);
Bitmap := TBitmap.Create;
Bitmap.LoadFromFile('c:\Program Files\Common Files\CodeGear Shared\Images\Splash\256color\factory.bmp');
Form1.Canvas.BrushCopy(MyRect, Bitmap, MyRect, clBlack);
Form1.Canvas.CopyRect(MyOther,Bitmap.Canvas,MyRect);
Bitmap.Free;
end;
