[SOLVED] TBGRABitmap filter

[BubikolRamios]

if canvas clear is executed then it is clear that image has graphic, but it is not changed in any way by filter.
Any clue ?

Code: Pascal  [Select][+][-]

1.       image := TBGRABitmap.Create(Bitmap);
2.       image.FilterGrayscale();
3.       //PaintBox1.canvas.Clear;
4.       PaintBox1.canvas.Draw(0,0,image.Bitmap);  
5.
