Converting a PDF to Tiff for each page with Ghostscript?

Xeratul · 03-23-2015, 05:13 AM

Hello,

I have found this command for a single page.

Code:

gs -q -dNOPAUSE -r600 -sDEVICE=tiff24nc -sOutputFile=a.tif a.pdf -c quit

However I would like that GS creates for each page a TIFF file.

Looking forward to hearing you.

This page appears to have an answer: http://stackoverflow.com/questions/1...multipage-tiff

I have not tried it.

Edit0: My first try failed, hmmm.
Edit1: A second "hmmm", they (individual images) are created because I can open them up with Gimp. Maybe I need a third cup of coffee.

If you have ImageMagick installed "identify" will show the individual file names on the cli and "display" will open the file on the X server.

I would prefer to use GS since it is much faster and stabler than imagemagick.

Did you try the "gs" commands on the link? As far as I can tell they work fine.

I use this in one of my scripts:

Code:

/usr/bin/gs -sDEVICE=png16m -r 200 -o outfile-\%02d.png infile.pdf

This is a call to convert a pdf to multiple PNGs. You'd need a different sDEVICE for TIFF. Note the %02d. It specifies how the output files are numbered. I am not sure about the space in -r 200 between r and 200. In my script there is no space.

@ Xeratul

You need to add a "%d" as part of the output filename, like so:

Code:

gs -q -dNOPAUSE -r600 -sDEVICE=tiff24nc -sOutputFile=a%d.tif a.pdf -c quit

I've tested it myself on my pdf file and it worked just fine and it made a series of tif pages in numerical order. Let us know if this works for you.

PS: The conversion is not instant. It will take a few seconds or more depending on length and complexity of the pdf file.

Did it work for you Xeratul? It should.

Here is an excerpt of the manpage for gs

Quote:

You might want to print each page separately. To do this, send the output to a series of files "foo1.xyz, foo2.xyz, ..." using the "-sOutputFile=" switch with "%d" in a filename template:

-sOutputFile=foo%d.xyz

Each resulting file receives one page of output, and the files are numbered in sequence. "%d" is a printf format specification; you can also use a variant like "%02d".
