As a project manager I spend about half of my day taking screenshot of
bugs. My favorite screenshot tool of choice is Shutter. Primarily
because it has an nice lightweight editor that has an incremental number
placement tool that lets me annotate my screenshots.
However Shutter doesn't actually scale images. If you want to upload
this to your ticketing system and then embed it inline that's pretty big
if you have a big screen resolutions. For me I have a 1080 width and
generally that's just way to big for an inline image. Previously I would
just avoid having an inline image. I discovered you can create custom
actions with the file manager Thunar.
Here's how to set up a custom action with Thunar File Manager
convert -antialias -density 600 %f -resize 600 resized-%f #do note this replaces the exiting file.
