DiaVisViewPlugin - Renders dia and vdx files

Description

This has taken the original DiaView? and modified it for use with Trac 0.11, and at the same time included support for vdx and compressed files.

It has had very little testing. It has been set up as a separate hack to the original DiaView? so as not to break DiaView? for Trac < 0.11.

If the width was changed in the macro argument the displayed image would scale, however the source file stayed the same. To overcome this the width is checked using the image library, and if different it is re-rendered. Please see the link below for the image library.

Download and Source

Download the zipped source, check out using Subversion, or browse the source with Trac.

Example

To install download the archive, then either $ python setup.py install or copy it to the plugins directory of the particular project

Do not forget to enable the macro in trac.ini in the components section like this:

diavisview.* = enabled

Also ensure that dia (diagram editor) and the Python Imaging Library (cf. link above) are installed.

Attach a file you wish to display to the page as per normal. The files can be either dia or vdx, compressed or uncompressed.

Make suitable macro entries in the page. If a number is given after the filename it will be taken as the width. Please see the main image macro for all the options.

[[DiaVisView(Diagram1.dia)]]

[[DiaVisView(Diagram2.vdx, border=5)]]

Thanks to arkemp for the original.
