Creating overlays

Colored overlays are used to explain findings directly in the image. Here we show how these can be created and what types are available.

  • Search for the case you want to edit in the “Cases” tab
  • Open the case you want to edit by clicking on it
  • If you havent created a case yet check out the section about uploading images and case creation
  • Once you have opened the desired case, you should see the overview for the case
  • To switch to edit-mode, click on the “Edit”-button at the top left
