we are using Moodle 3.8.3 on a shared hoster (German hoster BelWue). Our pupils are submitting pictures taken by their mobile phones. The pictures are sized down for annotations by the Moodle system (the files are called image_page#.png). These pictures are always of the size 827x1169 pixels.
Problems occur when the original image is of much greater height than width. I attached an example image with resolution 2268x4032 pixels and the corresponding annotation image (heavily compressed due to forum restrictions). Note that the latter image is cut off on the bottom and thus cannot be annotated by the teacher.
Where can I adjust Moodle (or Ghostscript?) so pictures will not get cut off anymore?
Thank you very much for your answers - sincerely,
