latex-pax in Windows and Linux

In Windows

• I installed a full version of TeXLive 2024 from an ISO image. This already contains latex-pax.
• Download PDFBox 0.7.3 and extract the downloaded ZIP file to C:\.
• Create a pax.bat file with the following content.

  @echo off
  SETLOCAL
    
  set CLASSPATH=C:\PDFBox-0.7.3\lib\PDFBox-0.7.3.jar;%CLASSPATH%
  perl "C:\texlive\2024\texmf-dist\scripts\pax\pdfannotextractor.pl" %*
  

• Run pax.bat <filename>.pdf to generate a <filename>.pax file that contains the PDF informations of <filename>.pdf.

In Arch Linux

• Again, latex-pax is already installed.
• Install pdfbox by running yay -S pdfbox. You can also download PDFBox 0.7.3 and extract the downloaded ZIP file to /usr/share/java
• Create a /usr/bin/pax file with the following content.

  #!/bin/sh
    
  PAX_JAR=/usr/share/texmf-dist/scripts/pax/pax.jar
  # PDFBOX_JAR=/usr/share/java/PDFBox-0.7.3/lib/PDFBox-0.7.3.jar
  PDFBOX_JAR=/usr/share/pdfbox/pdfbox.jar
    
  java -cp $PAX_JAR:$PDFBOX_JAR pax.PDFAnnotExtractor "$@"
  

  Also run chmod a+x /usr/bin/pax as root user to allow everyone to run the command pax.

• Run pax <filename>.pdf to generate a <filename>.pax file that contains the PDF annotations of <filename>.pdf.
