See my comments, ANY form, whether image based or text base, can be

Hi Keith,

Thanks for that admonishment, where are different kinds of PDFs, e.g.,
o A PDF of "something" (anything), which can be a bitmap for all we know
o A PDF of pure text of some format (which is the easiest to deal with)
o A PDF in a specific editable "form" format, which is a special beast

To be clear, we're talking about the 1st item above; not the latter two.

For the first 2 types, here's a method that, while not slick, works:

Open the pdf with gimp.
Import with at least 200 or 300 dpi.
Each page will be a layer, so be sure to choose the correct layer(s)
to edit. (getting the hang of layers might take a couple minutes)
Export the finished product as "mng" (multi-part png).
Use ImageMagick's "convert" command to turn it into a multi-page
pdf again:
convert somefile.mng somefile.pdf

Ours were photocopies, IIRC. Or you could buy the expensive "real"
ones.

I always wondered why, in college, the graph paper was blue, and yet,
the Smith Charts were orange (or, later in life, green).

Just one of those things in life that we ponder...

Oh look! A butterfly!

IIRC, the blue grid tended to disappear when photocopied. Now to
ponder why that... lol. Perhaps to show just your graph without
the "distracting" grid?

Someone asked me to help them edit a multi-page PDF form where they
wanted it to look professional.

I'm always fascinated by this. Do they have the owner's permission to
modify the document? If so, why not get the source, edit it, and
regenerate the PDF. If not, this has the hallmarks of a breach of some
kind. We regularly get requests for this kind of thing, and we ask for evidence of permission first, evidence of ownership second, or evidence
of abandonment third. "Looking professional" wrt PDF forms really needs
the use of a designer and a document engineer.

Peter

Permission is implicit sometimes. For example, I recently had to fill in
and sign insurance documents. They emailed the form as a regular PDF (not
a fillable form). Rather than print it, scribble on the paper, scan it
back in, shred paper (such a waste). I brought it up in gimp to put nice
clean text into the fill-in areas and draw my signature. Save as .mng
and convert back to PDF with "convert -reverse file.mng file.pdf".
Not the slickest procedure and I'd hate to use that for any continuous production but it got the job done with no wasted trees/ink.
