The text in the PDF version of the Application Developers Guide appears only as black while the HTML version uses colored text to highlight some material. See attachment demonstrating this in Example 2.3 of the guide. I was glad to see I could label the severity of this issue as "trivial," but I also felt it was worth pointing out even if only to help make future iterations more readily understandable to new users.
Created attachment 310 [details] Example 2.3 states "Code modified from the previous example are shown in blue," but the text is all black.
Created attachment 311 [details] HTML version of the same section for comparison
Thank you for letting us know about this. It appears to have been like this back to at least Release 9.4 (December 2009). I'll try to understand how to configure the XML-to-PDF processor to generate colored text.
We do not have any color-capable markup in the DocBook XML -> FO conversion. The FO output is what is used to produce the PDF version of our documentation. Changing this will require some XML/XSL development effort.
Modifications to both the HTML and PDF (FO) markup are underway, now that I (think!) have figured out how to propagate color specifications into the PDF. If I am successful, I will update the 10.1 documenation on the G4 Web site.
