After you have inserted an image into your diagram, you can crop it (clip it) in various shapes.

1. Right click on an image on the drawing canvas and select Crop.
2. Resize the rectangular crop using the grab handles.
3. Drag the crop box to move it to another area of the image.
4. Change the shape of the crop:
   • Ellipse sets a circular or ellipse-shaped crop.
   • Rounded rounds the corners on the rectangular crop.
5. Click on Apply

This is a non-destructive crop. To reset the crop to the original image, click on Reset in the crop image dialog.
