In KDE:
- Double Click PDF, Opens it in PDF viewer "Okular"
- Select "Stamp" Annotation Tool
- Draw region to place stamp
- View stamp properties and click to select image source
- Select SVG file I always use that has my signature that I created using my wacom tablet.
- Adjust placement if needed
- Save file
Takes all of ~15 seconds. Don't see how that equates to moving mountains.
15 seconds and a wacom tablet. The killer part of the preview.app is that it uses the front facing camera to capture a signature, quite well if i might add.
