Win32 command line free PDF to PDF/A converter

Similar to the previous entry for Linux type machines. Note 8.71 seems to be
more stable than 8.64 Ghostscript. Ghostscript 8.70 had problems


GET : http://sourceforge.net/projects/ghostscript/files/GPL%20Ghostscript/8.71/gs871w32.exe/download

GET java runtime or SDK

Files needed:
Fixflag (see April post)- java programs to turn 'on' print flags in each hyperlink.
PDFA_def.ps (see April post)- PDFA postcript def file
pdfmarks (see April post) - file containing metadata. edit this to put in your values.
USWebCoatedSWOP.icc (see April post)- color def file
test.bat contains ghost script command and parameters


To Preserve Hyperlinks and turn print flag on, run first:

java -cp C:\pdftest\Fixflag\pdfbox.jar:C:\pdftest\Fixflag\commons-logging.jar:. FixPrintFlag Input.pdf Output.pdf

then run test.bat
-------------------------------------------------------------

Otherwise
Run: test.bat

-------------------------------------------------------------
Contents of test.bat:
"C:\Program Files\gs\gs8.71\bin\gswin32c.exe" -sDEVICE=pdfwrite -q -dNOPAUSE -dBATCH -dNOSAFER -dPDFA -dUseCIEColor -sProcessColorModel=DeviceCMYK -sOutputFile=pdfa_out.pdf PDFA_def.ps pdfmarks c:\pdftest\test2.pdf
Note: make sure to change name of file in test.bat to match input and output names.

Free way to convert an existing PDF to PDF/A

The following test resulted in a valid and verified PDF/A produced from the Linux command line.

Requirements:
Ghostscript 8.64 Only.
PDFBox 0.7.3
pdfmarks ( file to supply additional meta data)
PDFA_def.ps
USWebCoatedSWOP.icc

I converted the PDF to PDF/A running the following command:
gs -sDEVICE=pdfwrite -q -dNOPAUSE -dBATCH -dNOSAFER -dPDFA -dUseCIEColor -sProcessColorModel=DeviceCMYK
-sOutputFile=Out_PDFA.pdf PDFA_def.ps pdfmarks IN_PDF.pdf

The PDF/A created is named OUT_PDFA.pdf
If you verify the file at this stage it will show that there are Annotation print flags that are not set for each hyperlink

To fix that problem, it is necessary to set the print flag in each link by using a Java program I wrote called "FixPrintFlag.java".
FixPrintFlag.java uses PDFBox library to acces each link and set the print flag in the PDF file.

running FixPrintFlag:
usage FixPrintFlag input_pdf output_pdf

so : java FixPrintFlag Out_PDFA.pdf New_verifiablePDFA.pdf

using Adobe, New_verifiablePDFA.pdf verifies as a valid PDF/A

NOTE: don't try gs v 8.70 , it will error out early even if the pdf was modified by FixPrintFlag. Ther appears to be a bug in v8.70.


GPL Ghostscript 8.70: Annotation set to non-printing,
not permitted in PDF/A, reverting to normal PDF output


NOTE: It will work for gs v 8.71...
note on 8.71 , run the FixPrintFlag on the input pdf
then take the output from FixPrintFlag and use that as the input to gs 7.1
command above
the file that you get out from gs will verify as a valid PDF/A using Adobe.
