Description

You will use this notebook if you need to crop and/or rotate a set of images.

The application will ask you to select the images (FITS or TIFF) you want to modify. Then a User Interface (UI) will allow you to define the cropping region as well as the rotation angle to apply to the images. You will be able to browse through the images to check the result and then create the transformed images before exporting them to a new output folder as TIFF images.
