I need to convert some files from pdf to tiff in a vb 2005 application and I heard it's possible with ghostscript. How can I approach this. I use vb but I can translate to c# if necessary.

BCL Computers' Freebird software is available as a command line program. Freebird converts PDF to TIFF, JPEG, and BMP. For more information, visit our website at http://www.bcl-computers.com. If you use this you don't need to make complicated dll calls.

Try putting this CMD into the root of your ghostscript installation.

If it doesn't work then maybe ghostscript just can't do it.

~Alain
rem pdf2tif.cmd

rem Convert a pdf to a TIFF

rem Usage: pdf2tif.cmd input.pdf[output.tiff]
 

set GS_HOME=%~dp0

set GSC="%GS_HOME%bin\gsc.exe"

set fileinput=%1

set cmdfile="%GS_HOME%_%~n1.rsp"

if %2/==/ (set fileoutput="%~dp1%~n1%%d.tiff") else (set fileoutput=%2)
 

echo -q -dSAFER -dNOPAUSE -dBATCH > %cmdfile%

echo -sDEVICE#tifflzw -r600 -dTextAlphaBits=4 >> %cmdfile%

echo -dGraphicsAlphaBits=4 >> %cmdfile%

echo -sOutputFile#%fileoutput% -f %fileinput% >> %cmdfile%

%GSC% @%cmdfile%
 

if exist %cmdfile% erase %cmdfile%

apparently the following can also work from the command line.

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

Here's more code that claims it can do the same using ghostscript in powershell:

~Alain
$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

}

Here is a simple C# GS wrapper to convert PDF to JPEG which can easily be modified for TIFF:

Change the sDevice arg from jpeg to tiffg4 (assuming you want black & white).  Lose dTextAlphaBits & dGraphicsAlphaBits.  You can use the -r arg to adjust dpi.
