  System Drawing Rectangle - How does this happen?

  Sep 12, 2011 06:31 AM|yonatan1082|LINK

  I am using the following code :

  using (var thumbnailBitmap = new Bitmap(newWidth, newHeight, PixelFormat.Format32bppArgb))
                  using (var thumbnailGraph = Graphics.FromImage(thumbnailBitmap))
                  {

  thumbnailGraph.DrawImage(image,
                          new Rectangle(destX, destY, destWidth, destHeight),
                          new Rectangle(sourceX, sourceY, sourceWidth, sourceHeight),
                          GraphicsUnit.Pixel);

  }

  }

  And I get a 400X300 rectangle. the actual parameters are :

  thumbnailGraph.DrawImage(image,
                          new Rectangle(11, 0, 377, 300),
                          new Rectangle(0, 0, 800, 635),
                          GraphicsUnit.Pixel);

  if the point is 11,0 and the width is 377, how do I get an image of 400X300? I am so curious about this...

  If anyone knows, or can point me at the right direction, I will be grateful.
