Post by Azhar » Sun Jan 22, 2017 3:06 am

Hello everyone,

I have used Master PDF Editor in the past. Not a lot, but it has worked OK for what I needed. However, it used to be free in Linux, but now it looks like the free version "watermarks" the file. Not sure of that, though. You could download and install it and see what happens.

I find it much easier to edit the source document and then generate a new PDF. If you do not have access to the source document I suggest you try Master PDF Editor - it does a nice job with small changes and it is great for filling out forms. (I have never encountered the watermark.)

What sort of changes are you wanting to make?

I want to make a new file by combining contents of few other files.

Basically, its an exam paper, i teach to Cambridge O Level students and want to make an exam paper from the past papers published by Cambridge. Papers published from 2013 onwards are easily editable, open-able but the previous ones make my system stuck with 100% CPU usage (if i edit them in LibreOffice). I was able to work with them with Foxit Pdf editor under windows easily.

I daresay you're up against two different sub-formats of pdf. Could you please check an "editable" versus a "non-editable" file?

Code: Select all

pdfinfo good_file.pdf
pdfinfo bad_file.pdf
If so, I'd try to "normalize", i.e. reformat all pdf files to a common sub-format, presumably by means of good old Ghostscript 8)

That's what I expected. - As a next step, I'd try to reformat the 1.5 file(s) to 1.3 (or everything to PDF/A).

An exemplification you may want to start from: how to use ghostscript to convert pdf to pdf/a

However, as I recall from my past of working with ps / pdf files on a professional basis, Ghostscript is extremly powerful - as well as anything but user-friendly ("Taming of the Shrew", anyone?).

Therefore, I'd be glad to help you getting started. Feel free to send me copies of both test and/or other files (- mail address via PM).
