To start PDFEdit, type: pdfedit /path/to/pdf.file & pdfedit &. I'm not sure if this might also work for multipage pdf's. If you are using Ubuntu: sudo apt-get install pdfedit. Given some pdf called origin.pdf you want to add an image, e.g. sign.sh origin signature.png 10 400 690 a png of your signature, somewhere in the pdf, you run the script like this: Pdftk "$f.pdf" stamp "$f.1.signature.pdf" output "$f.1.signed.pdf" # stamp the original pdf with the new signature template pdf # create a new pdf with the same size as the original pdf with transparent background and the signature image positioned at the final positionĬonvert -density $density -size $pdfsize xc:transparent \( "$s" -resize $p% \) -geometry +$x+$y -composite "$f.1.signature.pdf" # just in case someone needs this: get the size of the signature image This command creates a new pdf origin.1.signed.pdf where the signature.png is scaled to 10% of it's size and positioned to 400圆90 in the pdf.

You might want to start by getting a nice rectangle with only the signature. For this I used the Rectangle Select Tool, then Edit > Cut, and Edit > Paste as New Image. Next I followed the steps to make the background transparent by using the Fuzzy Select Tool and pressing Delete.
This gets rid of the white background (important because in my case the picture didn't come out with a clear white, was more like grey) leaving only the black signature.
