Pdf Images as PNG in Wiki

Description

This plugin inserts vector graphics like PDFs or SVGs as PNG-images into a Trac wiki page or ticket.

It requires convert from ImageMagick. However, convert may fail on specific files. Additionally, Ghostscript is required for convert on Windows, which is available here.

The handling and the parameters are inspired by LaTeX includegraphics and the Trac ImageMacro.

Examples:

[[PdfImg(Book.pdf,width=400,page=100,caption="Page 100 from Book Example")]]
[[PdfImg(source:testpro/drawing.svg@10,width=600,caption="SVG-image from repository in version 10")]]
[[PdfImg(ticket:1:file.pdf)]]

Note: PDF conversion with ImageMagick-convert:

  1. may fail on specific PDFs. This is not a problem of the plugin, but of convert. In this case you will get an error like Can't display foo.pdf, ImageMagick->convert failed with errorcode=... , command=convert ...
  2. if not restricted to certain pages, it can take very long; example: Converting a PDF file of 400 pages by simply [[PdfImg(test.pdf)]] took several minutes! See #9874, #9875.

No configuration is needed, except when using the resource 'file:' the following configuration must be set:

Suppose your server is http://example.com and the webserver config mapped your local directory /absolute/entry/directory to the public directory entrydir, then your configuration for the file:-resource looks like:

[pdfimg]
file.prepath = /absolute/entry/directory
file.preurl = http://example.com/entrydir
