Depending on how label width and font size parameters are specified in the browser configuration, the PDF output has a label column of varied pixel width. I'd like to troubleshoot how this value is calculated. Is there a part of the UCSC codebase specifically relevant to how PDF output is generated?

Regards,

Alex

Dear Alex,

Thank you for your question about the UCSC Genome Browser. We generate postscript .ps or encapsulated postscript .eps output, and then run a standard Unix utility that converts it to .pdf.
The postscript routines can be found here:http://genome-source.cse.ucsc.edu/gitweb/?p=kent.git;a=tree;f=src/lib. The files are named:

pscmGfx.c // virtualization layer
psGfx.c // post script routines
psPoly.c // tiny little polygon thing.

When browsing this code, it may also be helpful to keep in mind the following README:http://genome-source.cse.ucsc.edu/gitweb/?p=kent.git;a=blob;f=src/README. I hope this is helpful. If you have any further questions, please reply to gen...@soe.ucsc.edu. All messages sent to that address are archived on a publicly-accessible Google Groups forum.
