Replace a image in a PDF using command line
Clash Royale CLAN TAG#URR8PPP
I need to process some PDF files. The task consists in exchange a given image file by another. My first problem is how to replace a PDF image from command line in a batch process. Next I'll try to address other problems like how to identify which is the image I need to replace (because the PDF files may have more than one image). But first I want to resolve the first problem: how to replace a image in a PDF by another.
I've read about poppler-utils and pdftk but as far as I Know, none of these tools allow to replace images into PDF.

If you find an answer it will be really interesting to know. After isolating the "problem page", you could use ImageMagick to insert an image into another and then convert it back to pdf: imagemagick.org/Usage/layers Also: superuser.com/questions/614784/…

Thanks @pidosaurus I was cosidering this options but it has a big problem: it implies to convert the PDF (or the signature page) to images. It's a problem because the resulting PDF will be much bigger in size and the user couldn't select a piece of text to copy and paste for instance.

lookup convert from imagemagick, and more so, the tools that ooconv from openoffice (now libreoffice, actually) provide -- I once hired someone to write a PPT to PDF convertor and these were the tools used.

OK ... I think pdflatex is the missing piece here.
The OP said he has looked into poppler-utils and pdftk. Let me add to that pdfimages. These, together with pdflatex are the pieces of a solution.
pdfimages -f 4 -l 20 -j -png target.pdf imageroot
In the example code above, pdfimages looks through pages 4 through 20 of target.pdf and extracts all images into files with names beginning imageroot.
poppler-utils provides pdftotext. I recommend the -layout option which does a great job keeping the document human readable.
pdftotext -layout $1.pdf $1.txt
The OP's objection to the imagemagick solution offered by pidosaurus is that
an image does not have extractable text. With the utilities I outlined, the OP will now have all the images as well as all the extracted text, and page numbers and contents are retained by the -layout option. The OP could identify the correct page of text and chuck it into a .tex file which ends with an %includegraphics directive and refers to the replacement picture by filename. You then pdflatex this and end up with a new single-page .pdf to insert into the rest of your document with pdftk. If you knew where in the text of the original page the image resided, you can %includegraphics [h] and get the image in exactly the right place.
