| | ==== Screenshots ==== |
| I use this script for taking screenshots, bound to the ''Print Scrn'' key with [[i3wm]]. It dumps a screenshot into my 'Pictures' directory, and makes a beep. You can set it to make a notification if you want. | I use this script for taking screenshots, bound to the ''Print Scrn'' key with [[i3wm]].

| {{tag>software}} | Without beep: |
| | |
| | <file bash screenshot.sh> |
| | #!/bin/bash |
| | import -silent -window root $HOME/Pictures/screenshot_`date +%y-%m-%d_%H-%M-%S`.png |
| | </file> |

| | ==== Image Conversion ==== |
| | |
| | Two main commands are ''convert'' and ''mogrify''. The distinction is that the former makes new files, and the later can overwrite existing files. |
| | |
| | This will convert all PNGs in the current directory to JPGs at quality 50 and scaled to 1200px width. |
| | |
| | <code bash>mogrify -format jpg -quality 50% -resize 1200x *.png</code> |
| | |
| | ==== Create PDF ==== |
| | |
| | To create a PDF from a bunch of PNG files in a directory: |
| | |
| | <code bash>convert *.png [name].pdf</code> |
