RE: dblatex Randomly Produces Bold Pages

[Tim Arnold <Tim.Arnold@sas.com>]

Hi Russell,

If you're including PNG images in the doc and they have an alpha or transparency channel, you get a bolded look on the page where the image appears.

This thread has a lot of details on the problem, but the fix is to remove the alpha channel from the graphic.

Subject: [docbook-apps] dblatex Randomly Produces Bold Pages

 

I'm using dblatex via Python to produce a PDF file on a Windows machine.  Here is my command line.

 

C:\xml> python C:\Python26\scripts\dblatex -P latex.hyperparam=colorlinks,linkcolor=blue my_file.xml

 

For some reason, on two of the pages, all text is bold, including the header and footer.

 

The XML has been validated using Jing against the RelaxNG schema.

 

Here are samples of the XML used to produce each of the pages.  Each is in an appropriate context.  Ellipses represent plain text.

 

Sample 1:

 

                                                <procedure>

                                                                <step performance="required">

                                                                <step performance="required">
