PdfImages as PNG in Wiki

Description

Insert vector graphics like PDFs or SVGs as PNG-images into a wikipage or ticket.

Requires convert from ImageMagick, 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)]]

Acknowledgement

Attention: PDF conversion with ImageMagick-convert:

1. may fail on specific PDF s. This is not a problem of the plugin, this is a problem 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)

Source

You can check out PdfImagePlugin from here using Subversion, or browse the source with Trac.

Example

[[PdfImg(Book.pdf,width=400,page=100,caption="Page 100 from Book Example")]]
[[PdfImg(sketch.svg,cache=False)]] 
[[PdfImg(OtherPage:foo.pdf)]]
[[PdfImg(file:relpath/to/foo.pdf)]]

Configuration

No configuration is needed except to use the Resource 'file:' the following configuration must set:

Assume 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
