PDF to TIFF

Astinia

Hello everyone,
Could someone give me an advice how to convert pdf to tiff? free library or dll?
I've found some answers on StackOverflow, however they all about not free product and most about Ghostscript.
May be there is something else?

Thanks a lot for your time

There's an AGPL Version of Ghostscript.

MuPDF might be another option. It has the very same licensing as Ghostscript. I like it's rendering result better than Ghostscipt's. It does not create tiff images, though. So it would have to be paired with an image converter like e.g. ImageMagick.

Astinia

Thanks. I had a look on ImageMagick before. Thanks one more time

Hi Astinia, just wondering if you managed to covert pdf into tiff, I need to convert pdf into jpg, any ideas?

Astinia

Nope.. Nothing free..

You can use the free versión of Ghostscript and convert to jpg or tiff.

For TIFF

gs -q -dNOPAUSE -sDEVICE=tiff24nc $param -r200 pdfFile -c quit

For JPG

gs -q -dNOPAUSE -sDEVICE=jpeg $param -r200 pdfFile -c quit

You only need to change the -sDEVICE parameter.

qs is the name of your Ghostscript executable,in my installation is this:

And pdfFile is the full name of your PDF.

C:\Program Files\gs\gs9.19\bin\gswin64c.exe

More option for TIFF files:

tiffgray
Produces 8-bit gray output.
tiff12nc
Produces 12-bit RGB output (4 bits per component).
tiff24nc
Produces 24-bit RGB output (8 bits per component).
tiff48nc
Produces 48-bit RGB output (16 bits per component).
tiff32nc
Produces 32-bit CMYK output (8 bits per component).
tiff64nc
Produces 64-bit CMYK output (16 bits per component).

Regards.

Sorry in my last post I made some mistakes:

$param is the parameter for the output file
$param = -sOutputFile=outFile

And qs is the name .................,
Would be gs (C:\Program Files\gs\gs9.19\bin\gswin64c.exe)

Regards.

Thanks

Yeah I have tried ghost script and manage to convert file in NAV using it, but output quality is not great.

ftornero

Well, you can use the parameter -r to increase the quality.

i.e.

-r600

or

-r1200

etc.

Regards.

hrishi

it worked by changing it to -r600
