Fix image formatting in BRL-CAD's Docbook Documentation (any one large document or 4 smaller documents) #4
completed by: Sharan Narayan
The majority of BRL-CAD's documentation is defined as DocBook XML files, from which other formats (HTML, PDF, man page, etc.) can be generated. PDF files present a particular challenge, and have some very specific requirements to achieve ''good'' formatting.
BRL-CAD's DocBook files need to uniformly use a style of image inclusion that is aware of what ''role'' the image is supposed to serve. A ''basic'' image inclusion example looks like this:
<mediaobject> <imageobject> <imagedata align="center" fileref="../../lessons/en/images/img.png" format="PNG"/> </imageobject> <para> Caption goes here. </para> </mediaobject>
This task involves switching image inclusions that use the above style to something like the following:
<mediaobject> <imageobject role="html"> <imagedata align="center" fileref="../../books/en/images/img.png" format="PNG"/> </imageobject> <imageobject role="fo"> <imagedata align="center" fileref="../../books/en/images/img.png" format="PNG"/> </imageobject> <para> Caption goes here. </para> </mediaobject>
The ''role'' flag to imageobject provides the opportunity to specify different image formatting options when the output is HTML (role=''html'') or PDF (role=''fo'').
The captions should be preserved as above on mediaobjects that have them, but mediaobjects without a caption should also be converted and there is no need to add a caption in such cases.
Any patch that makes changes to the DocBook sources should result in a successful ''make doc'' build test. This won't generate PDF documents, but it will validate the XML files and produce HTML. Your updated files must pass ''make doc'' to be accepted, preferably submitted in patch format.
This task is simply to do the above conversion for all images in the file or files, not to introduce PDF specific formatting. If all image inclusions have been converted successfully and a student is interested in actually fixing the formatting, please discuss it with us on IRC or the mailing list. Follow-on tasks are likely.
- doc/docbook/*/en/*.xml (anything with mediaobject tags)
