Best way to convert pdf files to tiff files [closed]

I have around 1000 pdf filesand I need to convert them to 300 dpi tiff files. What is the best way to do this? If there is an SDK or something or a tool that can be scripted that would be ideal.

Use Imagemagick, or better yet, Ghostscript.

http://www.ibm.com/developerworks/library/l-graf2/#N101C2 has an example for imagemagick:

convert foo.pdf pages-%03d.tiff

http://www.asmail.be/msg0055376363.html has an example for ghostscript:

gs -q -dNOPAUSE -sDEVICE=tiffg4 -sOutputFile=a.tif foo.pdf -c quit

I would install ghostscript and read the man page for gs to see what exact options are needed and experiment.

Using GhostScript from the command line, I've used the following in the past:

on Windows:

gswin32c -dNOPAUSE -q -g300x300 -sDEVICE=tiffg4 -dBATCH -sOutputFile=output_file_name.tif input_file_name.pdf

on *nix:

gs -dNOPAUSE -q -g300x300 -sDEVICE=tiffg4 -dBATCH -sOutputFile=output_file_name.tif input_file_name.pdf

For a large number of files, a simple batch/shell script could be used to convert an arbitrary number of files...

I wrote a little powershell script to go through a directory structure and convert all pdf files to tiff files using ghostscript. Here is my script:

$tool = 'C:\Program Files\gs\gs8.63\bin\gswin32c.exe'
$pdfs = get-childitem . -recurse | where {$_.Extension -match "pdf"}

foreach($pdf in $pdfs)
{

    $tiff = $pdf.FullName.split('.')[0] + '.tiff'
    if(test-path $tiff)
    {
        "tiff file already exists " + $tiff
    }
    else        
    {   
        'Processing ' + $pdf.Name        
        $param = "-sOutputFile=$tiff"
        & $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 $pdf.FullName -c quit
    }
}

1) Install GhostScript

2) Install ImageMagick

3) Create "Convert-to-TIFF.bat" (Windows XP, Vista, 7) and use the following line:

for %%f in (%*) DO "C:\Program Files\ImageMagick-6.6.4-Q16\convert.exe" -density 300 -compress lzw %%f %%f.tiff

Dragging any number of single-page PDF files onto this file will convert them to compressed TIFFs, at 300 DPI.

using python this is what I ended up with

import os
os.popen(' '.join([
                   self._ghostscriptPath + 'gswin32c.exe', 
                   '-q',
                   '-dNOPAUSE',
                   '-dBATCH',
                   '-r300',
                   '-sDEVICE=tiff12nc',
                   '-sPAPERSIZE=a4',
                   '-sOutputFile=%s %s' % (tifDest, pdfSource),
                   ]))
