Dynamsoft TWAIN Products

The Question:-

When the control is on my form and some images have been scanned, the user can draw a frame on the control, how do I access this frame's position / size details? (I wish to use it to crop the current image, and then to set the area of the next scan to that same area using SetImageLayout).

The bug:-
Enabling exception throwing (DNTwain.IfThrowException = true;) causes bizarre "success exceptions"
SetImageLayout suffers from this issue, turning IfThrowException off the code runs fine and the ImageLayout is set just fine.

Suggestion:-
The image editor shows your copyright in the about box, can you either allow us to set the content of that dialog, or allow us to disable it, just like we can customise the image editor window title.

Many thanks,

- Anthony

Hi Anthony,

You can use OnImageAreaSelected to get the position of a selected area. For more information about this event, please refer to:
