Editing the PDF files by changing the /MediaBox line works fine,
but as at least two people said "caution, do not change the number of bytes"
in the PDF file. (I'd forgotten and relearnt the hard way.)
That creates a problem as two of the /MediaBox parameters are zero's and need
(typically) changing to three and four figure numbers.
Suspect I could get around that by having some gratuitous material in one of
the PDF Document Information Fields and then compensating by deleting the
right number of bytes from there.
"while embedding pdf page as an image"
Would that lose the hyperlinks (pdfpages, gs, do)?
(Sorry I'm a simple Latex man so I'd need to do some head scratching to use
"Are all these pages to be cropped in the same way"
Yes, in that I just chop the white space off the bottom (and add back a
small margin). No in that they are all different lengths.
I find producing cropped (or cropped plus margin) PDFs increasingly useful.
Without hyperlinks it is quite easy, but it would be nice if it was just a
direct option without running 'pdfcrop' afterwards.
A fast (and I suspect dirty) use was a parallel translation Arabic:Chinese.
Both inputs were in UTF-8. 'ucs' and 'arabtex' seemed to be fighting over
encodings, so I just produced all my paragraphs as individual PDF images.
Thanks again for all the wisdom,
If anyone tries the script in my message of Mon, 20 Sep 2004 03:58:36 +0000
system( "mv temp-files/tmp.pdf /new_pdf/$filename" );
should have read
system( "mv temp-files/crop.pdf /new_pdf/$filename" );
