Best way to convert pdf files to tiff files

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),
                   ]))

The PDF Focus .Net can do it in such way:

1. PDF to TIFF

SautinSoft.PdfFocus f = new SautinSoft.PdfFocus();    

string pdfPath = @"c:\My.pdf";

string imageFolder = @"c:\images\";

f.OpenPdf(pdfPath);

if (f.PageCount > 0)
{
	//Save all PDF pages to image folder as tiff images, 200 dpi
	int result = f.ToImage(imageFolder, "page",System.Drawing.Imaging.ImageFormat.Tiff, 200);
}

2. PDF to Multipage-TIFF

//Convert PDF file to Multipage TIFF file

SautinSoft.PdfFocus f = new SautinSoft.PdfFocus();

string pdfPath = @"c:\Document.pdf";
string tiffPath = @"c:\Result.tiff";

f.OpenPdf(pdfPath);

if (f.PageCount > 0)
{
	f.ToMultipageTiff(tiffPath, 120) == 0)
	{
		System.Diagnostics.Process.Start(tiffPath);
	}
}   

How about pdf2tiff? http://python.net/~gherman/pdf2tiff.html

ABCPDF can do so as well -- check out http://www.websupergoo.com/helppdf6net/default.html">http://www.websupergoo.com/helppdf6net/default.html</a>

Required ghostscript & tiffcp Tested in Ubuntu

import os

def pdf2tiff(source, destination):
    idx = destination.rindex('.')
    destination = destination[:idx]
    args = [
    '-q', '-dNOPAUSE', '-dBATCH',
    '-sDEVICE=tiffg4',
    '-r600', '-sPAPERSIZE=a4',
    '-sOutputFile=' + destination + '__%03d.tiff'
    ]
    gs_cmd = 'gs ' + ' '.join(args) +' '+ source
    os.system(gs_cmd)
    args = [destination + '__*.tiff', destination + '.tiff' ]
    tiffcp_cmd = 'tiffcp  ' + ' '.join(args)
    os.system(tiffcp_cmd)
    args = [destination + '__*.tiff']
    rm_cmd = 'rm  ' + ' '.join(args)
    os.system(rm_cmd)    
pdf2tiff('abc.pdf', 'abc.tiff')

You could also use pdf2ps, ps2image and then convert from the resulting image to tiff with other utilities (I remember 'paul' [paul - Yet another image viewer (displays PNG, TIFF, GIF, JPG, etc.])

Disclaimer: work for product I am recommending

Atalasoft has a .NET library that can convert PDF to TIFF -- we are a partner of FOXIT, so the PDF rendering is very good.

Maybe also try this? PDF Focus

This .Net library allows you to solve the problem :)

This code will help (Convert 1000 PDF files to 300-dpi TIFF files in C#):

    SautinSoft.PdfFocus f = new SautinSoft.PdfFocus();

    string[] pdfFiles = Directory.GetFiles(@"d:\Folder with 1000 pdfs\", "*.pdf");
    string folderWithTiffs = @"d:\Folder with TIFFs\";

    foreach (string pdffile in pdfFiles)
    {
        f.OpenPdf(pdffile);

        if (f.PageCount > 0)
        {
            //save all pages to tiff files with 300 dpi
            f.ToImage(folderWithTiffs, Path.GetFileNameWithoutExtension(pdffile), System.Drawing.Imaging.ImageFormat.Tiff, 300);
        }
        f.ClosePdf();
    }

I like PDFTIFF.com to convert PDF to TIFF, it can handle unlimited pages
