Hi Tobias,

When doing a selection, the selection is done on the displayed image. So when saving you do

need to adjust your coordinates in the source image. The ImageScrollBox has two graphic

properties, Graphic, and DisplayedGraphic. Graphic is the source (non resized image). The

coordinates of the selection are with respect to the displayed graphic. You need to scale

your coordinates according to the ZoomPercent.

I have checked, and with the latest version, the ZoomPercent property is updated when the

ZoomMode is set the zmFitToPage. Are you using version 1.1?

Best regards,

Michel
