I call drawing onpaint inside

 using (Graphics gMemCanvas = Graphics.FromImage(memCanvasBmp)) //This is the background image  BitMap           
   using (Graphics gMem = Graphics.FromImage(memBmp))//This is a drawing of the BitMap               
  GraphicCanvas.InitCanvas(gMemCanvas, _gCanvas, pCanvas, _zoom); // This is a painting background image              
gMem.DrawImage(memCanvasBmp, 0, 0);///The process of drawing the background image on the display                
   pCanvas.Image = memBmp;          

After numerous zoom I finally causes the program to die. . How to improve it. . If I replaced
For GraphicCanvas.InitCanvas (gMemCanvas, _gCanvas, pCanvas, _zoom);
With a drawing surface with an GraphicCanvas.InitCanvas (gMem, _gCanvas, pCanvas, _zoom) ;/ / draw graphics and background image and nothing, but such is not inefficient it.
