I did look at Inkscape, but from what I can tell it only converts to other vector graphic formats such as SVG or PDF files.
I saw a couple websites that have older versions of Paint Shop Pro & they appear to be free because there is no mention about buying them. But that sounds too good to be true. Maybe it's legit because the versions go back to something like 2004 to 2007. However I'm not about to experiment & am looking for a recommended safe download.
