RE: DOCBOOK-APPS: Visio Vector Graphics -> DocBook XSL

["Rankine, Alastair J (Alastair)" <arankine@avaya.com>]

A followup to this.

Thanks to Georges Schmitz for inspiring me to persist with the Adobe printer driver / ghostscript combination. Here's what works for me, starting with an open Visio document:

1. Print the page to a file using the Adobe postscript printer driver. Note this should be set to use EPS output. Give the file a .ps extension.

2. Open the .ps file in GSView and use the PS->EPS conversion to make an .eps file. This is an important step to fix the bounding box.

3. Use the epstopdf tool (part of cygwin's tetex package, not to be confused with the ps2pdf tool in ghostscript which apparently does something similar!) to produce your .pdf

4. Include this in your docbook document as <imagedata fileref="foo.pdf" format="PDF>

5. Process it with PassiveTeX and admire the result.


Some gripes:

- Any text inside the Visio diagram is converted to a bitmap by (err, something). The result is lovely smooth lines and boxes with horrible jaggy text inside them. Is there any way to stop this happening?

- The whole process is sufficiently byzantine that I seriously suspect it will impede the adoption of DocBook. Of course SVG will save the day (won't it?) but as of right now I am not exactly rushing to recommend DocBook to my colleages (at least not in combination with Visio).

- I just have to ask: is there any way to stop PassiveTeX from dumping all of it's input XML-FO to the console? It's really annoying and I suspect slows down the processing considerably...

(http://www.cs.uq.oz.au/~emmerik/visioeps.html) on how to convert Visio files to EPS for use in LaTeX, and I assume the same principles apply for PassiveTeX (bear in mind I am a TeX ignoramus!)

It was a few weeks ago that I tried this, but I could not get it to work.


So that's it - any others that I have missed?

Comments appreciated!


One last thing: SVG is not a supported format attribute for the imagedata tag in the DocBook DTD (4.2RC1), should this be raised as an RFE?
