Compress PDF Output
The new -compress-pdf parameter can be used to reduce the size of the PDF output file for easier storage and sharing.
Merge Multiple PDFs
It is now possible to merge multiple PDFs together. Depending on where you want the additional PDFs to be inserted, you can use the new -insert-after or -insert-before parameters to provide a semicolon-separated list of PDF files to be merged with the currently generated PDF.
Generate Separate Files from Fragments of a PDF
It is now possible to generate individual fragments of a PDF as separate files using the new -oxy-pdf-extract-file CSS property, with the file name specified by the property value. This is particularly useful if you want separate PDF files for each chapter of a publication, alongside the whole book.

Oxygen PDF Chemistry version 27.1 is a maintenance release for the CSS Paged Media processor used for obtaining PDF output from HTML or XML documents through CSS styling. This version adds the ability to control Chemistry console logging, implemented various bug fixes, and addressed issues that were reported by the community.

Core
Control Logging
It is now possible to control the Chemistry console logging by using a custom logback.xml configuration file along with the new -log-file parameter. This is helpful if you want to hide the INFO messages or write the logs into a separate file.
