Manual paste a graphic into the PDF

Create a scanned signature

• Write your signature on a sheet and scan this.
• If your scan is not an image file (png, jpg, gif, tiff,...) than open it and make a screenshot (flameshot on thinlinc) and save that one as an image.
• Remove the white background so it becomes transparent - than it's quite easy to paste it in your PDF
  • In thinlinc, with the file manager, with mouse over the file choose 'remove background' > you get a new <file>.transparent.trim.png

Paste the scanned signature to the PDF

• In thinlinc open the program Xournal++.
• Drag and drop the signature image to the right place, size and reposition it.
• Export the file as PDF
  • Unfortunately, xournal++ complains if the exported file has the same filename as the original one - choose a different one.
