I'm try to move my current paperwork routine towards a paperless workflow (for the “administrative” type of papers, of course… not for serious reading tasks). There is one major annoyance thwarting me: people sometimes require me to print, sign and scan documents. They will not allow me to insert my scanned signature in an electronic file (even converted to PDF). It's for unimportant papers (e.g., not for contracts!), it's a waste of time, but I cannot make them budge.
Thus, I want to design a filter that takes PDF files as input, and gives them a “scanned document” look. What I have thought of so far:
Rasterization at not-so-great resolution. I have a ghostscript-based filter that does it, and I've used it a few times already. But, the documents keeps their “pristine” aspect: white background is still white, etc.
So, I considered getting a “scanned paper” texture from scanning a blank page, and apply it to my document. But: if I put it in front of the content with low opacity, the text might become too blurry; and if I put it behind the content, it works only if content has a fully transparent background (which is not always true for my documents).
Now, I'm thinking TeX/LaTeX would be great tools to do that, but I cannot translate this nice idea into specifics…
So, what would you suggest?
