It is opened by selectingfrom the main menu or from the context menu on an image file in the File Navigator.

- On the left the source image is loaded with the button. The viewport displays the original image with the perspective frame on top. That frame may be adjusted in order to crop the facade or element of choice.
- The right viewport shows the perspectively corrected frame selection from the left. When adjusted readily, the output image is stored with
