hi ginsonic, 
 
maybe you must the picture first tell the width and height of the bitmap like 
 
Pic3.Bitmap.Width := 200; 
Pic3.Bitmap.Height := 200; 
Pic3.Bitmap.Canvas.Brush.Color:=clBlack; 
Pic3.Bitmap.Canvas.FillRect(RECT(0,0,200,200));

Hi to all . 
I have 3 TPicture objects and a Canvas . 
 
Pic1 - store a jpeg file 
Pic2 - store a jpeg file 
and Pic3 - store a black bitmap : 
&nbsp; 
Pic3.Bitmap.Canvas.Brush.Color:=clBlack; 
Pic3.Bitmap.Canvas.FillRect(RECT(0,0,200,200)); 
 
For the case : 
&nbsp; &nbsp;Canvas.Draw(0,0,Pic1.Graphic); 
I can see in canvas Pic 1 . 
 
For the case : 
&nbsp; &nbsp;Pic1.Assign(Pic2); 
&nbsp; &nbsp;Canvas.Draw(0,0,Pic1.Graphic); 
I can see in canvas Pic 2 . 
 
But for : 
&nbsp; &nbsp;Pic1.Assign(Pic3); 
&nbsp; &nbsp;Canvas.Draw(0,0,Pic1.Graphic); 
I can't see anything . In normal case I must see a black square . 
 
Where I wrong ?
