Hi Jim,

From my experience, you need to set the size before the image gets to your software. That is, use the scanning interface of your HP scanner to determine the resolution and size of the image. The you can use the TDibGraphicPrinter to printer the graphic in the size that you need.

You can always use the TResizeTransform after receiving an image to change its size, but it is better to have your scanner scan at the right size.

Best regards,
