I am using version 14 Leadtools for .NET class Library.

With out using RotateViewPerspective, I would able to user Slipter, Whiteout, or make a regional selection on the image. However, when I rotate the image by calling RotateViewPerspective function. The rotation function work fine, but when I try to do a regional selection on the image, it take about 10 - 30 seconds for a selection and I would not be able to perform Slipter, White Out, etc. It seem like the Image is Locked up.

Is there a solution or work around this issue.

Thank you in advance.

How are you drawing the region? I set InteractiveMode to Region,
but when I draw the region is doesn't show up. I think this is
because when you rotate the view perspective, only the display is
changed; the image data stays as it is. I will check with
development, but first I need to know what exactly you are doing to make sure we are doing the same thing.

I drew the region by dragging the mouse. basically, it capture the mouse move and press. somehow, when I used the RotateViewRespective, I could not perform other functionalities.

Thank you

You were mention something about using RotateViewPerspective is just rotate about the View of it but not the data. Is there a way to rotate the data too. Because it seen like the rotation mess up everything else.

thank you

That is correct, and I think this may be the cause of the
problem. If you want to rotate the data as well, then use the RotateCommand class.
