Multipages pdf to multipages tiff

Post by paquilanti » Mon Oct 15, 2012 3:23 pm

Hi all,

I've tried this cmd: nconvert -out tiff -xall -multi cx.pdf
But i only get the first page of the pdf.
Any ideas...?

Thanks in advance

Hi Pierre,
Thanks for your time, unfortunately your suggestion did not work(first page only) I also tried with XnConvert but no luck so far.
For infos the pdf’s version: pdf 1.3( Acrobat 4.x)
Size: 3370 Ko,
Dimension: 209,9 x296,7 mm
Pages: 7
I have been able to do it with manually with PDFcreator but I prefer to use nconvert for batch purposes and faster encoding.
I hope it can be done…

Does this answer your question, Paul?

Thanks XnTriq,

I have run your code but I get this error “Error: Don't know how to read this picture” when I tried with those pdf’s versions.

Production: Version: Size: Dimension:
Gpl Ghostscript 8.64 1.4 (Acrobat 5.x) 569KB 210x297
Konika MINOLTA 1.4 (Acrobat 5.x) 114KB 210x297
Acrobat Distiller 8 1.6(Acrobat 7.x) 2,25MB 210x297

Those files are simply scanned documents without fancy stuff (password protection, etc.)

So far I have been able to run those cmds with the document I was after:

Production: Version: Size: Dimension:
unknown 1.3 (Acrobat 4.x) 569KB 210x297

nconvert -out tiff -xall -multi cx.pdf
nconvert -xall -multi -out tiff -o file.tif file.pdf
nconvert -o foo.tif -out tiff -xall -multi bar.pdf

The results Is that I get only the first page of the pdf file.

I start to think that the problem lies to the software to be able to read properly the pdf.

PS
Unfortunately my topic has been duplicated. I did post it on the XnConvert forum but the Moderator thought it belongs here… of course I have tried XnConvert, not luck either!

You can upload the sample(s) to a free file hosting service like Wikisend or MediaFire and post the link.

Hello,

I'm facing the same problem. It looks to me this is because NConvert doesn't recognise the format / page size / dimensions correctly if e.g. the orientation changes in the PDF. This can be seen from the output where the input PDF has four pages and can be viewed without problems with e.g Foxit:

Code: Select all

nconvert -out tiff -rmeta -xall -multi -c 2 -dpi 300 -grey 8 -floyd -sharpen 20 -v 1015120145.pdf
** NCONVERT v6.21 (c) 1991-2011 Pierre-E Gougelet (Oct 23 2012/16:18:19) **

The first TIFF page looks brilliant, but as one can see, the correct height of 2478 is not recognised for subsequent pages, but a far too small height of 66 is "assumed". Therefore the pages 2-4 of the TIFF are corrupt, just a small stripe is shown or nothing at all.

Thanks and regards,
RotBlitz

Nevermind. As GhostScript needs to be installed when using NConvert with PDFs, you simply let do it by GhostScript (latest version!):

Code: Select all

gswin32c -sDEVICE=pdfwrite -dSAFER -o 1015120145.%%02d.pdf 1015120145.pdf
rem The last split PDF is just an empty page, so let's delete it:
for %%e in (1015120145.??.pdf) do set last=%%e
del %last%
del 1015120145.pdf
nconvert -o 1015120145.tif -out tiff -rmeta -xall -multi -c 2 -dpi 300 -grey 8 -floyd -sharpen 20 -D -v 1015120145.??.pdf
This even sets correct orientations (portrait vs landscape) for each page. If you want to keep the original orientation of the whole PDF, use this:

Code: Select all

gswin32c -sDEVICE=pdfwrite -sPDFSETTINGS=prepress -dSAFER -o 1015120145.%%02d.pdf 1015120145.pdf
Whatever, this is a workaround only, and it preferably would been fixed in NConvert itself.

Cheers,
RotBlitz

I am trying to convert a pdf to tiff and am Getting "Error: Don't know how to read this picture (*********.pdf" for every pdf i'm trying to convert. Most are multipage and using -xall -multi -c 1 .... not sure what i'm doing wrong here.

EDIT: As an FYI i do have ghostscript and it works on single page but not multi i get GPL GhostScript 9.10 : Unrecoverable error exit code 1 Error : -100
