I had to print a couple of PDFs recently to send to someone, but I wanted to redact (black out) a couple small bits of text.
A quick google search didn't turn up any tools for this specific purpose, so I fell back to imagemagick & gimp:
convert document.pdf document.png
- (use paintbrush to black out text)
- print redacted page from gimp
- print remaining pages from xpdf
The problem with this strategy is that the conversion process (from PDF to PNG or whatever other format) loses quality. I tried editing the PDF in gimp but it didn't work right away.
Is there a specific tool that permits redaction in this way? (It doesn't even need to be "real" redaction -- I'm not sending a softcopy so "fake" redaction will work because the hardcopy can't be hacked to reveal the underlying text.)
Or, is there a trick to being able to edit PDFs in gimp?
