Although I can't show it because of privacy concerns, one thing I did today with Scribus was to send a patient a note about her brain MRI scan describing some findings, but also included some selected images, with arrows and annotation to show her what I was talking about.
I captured the images from Windows, since the hospital's software requires Internet Explorer. Then I rebooted to Linux, and in short order in Scribus was able to do this. I could also have done it in Gimp or Inkscape, but for sizing the image, placing it precisely on the page, adding the arrows and the textframe, Scribus was by far the quickest, easiest route. Greg
