RE: Saving PDF File With Xywrite

["Brian Henderson" brian-henderson@xxxxxxxx]

No Robert, PDFs are ASCII...or at least some TYPE of ASCII. I just edited 70
of them with Textpad, a plain text GUI editor. Changed, added to, and saved.
They all open in Reader and contain the changes I made.

Intuitively, you'd think they were binary, but if you open one up you'll see
they are MOSTLY plain text. I do believe there are SOME binary (?) aspects.
Some characters don't display (just little squares). I guess the real
mystery is why Textpad can save the file without corrupting it, if it
contains ANY binary characters. That's what made me think of code page as a
possible relationship. Maybe the little squares are simply outside the range
of Textpad's (and Xy's) current codepage, but Textpad doesn't mess with
anything it can't interpret...whereas Xy isn't that discriminating and
changes the characters into something else.

I'm completely guessing about all this. I don't know enough "deep-geek" in
this area to really make a truly educated guess.

PDFs are binary files! No can edit in XyWrite. What exactly are you trying
to
edit -- the Postscript commands? You can't edit the text itself, certainly,
because it's binary -- just glyphs. If you're simply patching something
small
without adding/subtracting bytes, write a DEBUG script and apply it all
files
-- boom, done! More info needed...
