Hello,

I'm using AnnContainer to draw some ocr zones. My problem is when I change the scale of the image, then the zones are no longer in their correct places. I don't find the way to correct this issue.

Attached a sample projet to reproduce this behavior.

Thanks for help.
Regards.

Hello,
Please take a look at our WPF Annotation demo and modify your implementation accordingly. It uses AnnAutomationManager to link the RasterImageViewer to the AnnotationContainer so that any scaling on the Viewer's image will update the annotations accordingly.
