# Customizing PDF output

You can adjust various aspects of PDF output by changing parameter settings or using a theme file. For more complex customizations, you can create or install custom plug-ins.

For example:

- To print the file names of the graphics underneath figures, set args.artlbl to yes.
- To disable the subsection links on the first page of each chapter, set args.chapter.layout to BASIC.
- To change the name of the PDF file to something other than the input map name, set outputFile.base to the desired file name (without the .pdf extension).

Note:
