Package: graphviz

Severity: normal
Gdtclft does not works with proportional fonts correctly.
One of our customers is using gdtclft to create png-graphics with
his CGI-scripts written in TCL. The output of fonts in the graphics
is not correct. In the first example the word 'Barometer' shows up
like 'B arom eter' in the generated png:

A correct version looks like this:

Another example of broken fonts where the last two lines are
too wide and most fonts look ugly:
http://www.huecker.com/cgi-bin/fonts.cgi
compared to the correct version where the lines fit and the
fonts are better looking:

The correct versions where created by the same CGI but on SuSE-Linux 7.1
with tclsh 8.4 and gdtclft 2.2. I'm filing this bug-report on behalf one
of our custumers who uses the SuSE-Box as his home-machine.
He has contaced the author of Graphviz/Gdtclft, Jon Ellson, who
suggested to file this bug-report. He supplied the following patch
which I used against graphviz-2.2.1-1sarge1 and graphviz-2.8-2.2
but it did not help to improve the situation:

I found that gdtclft wasn't using fontconfig, which could possibly be the
cause of the strange text problem. If you can build from source, try
applying the attached patch.

I recommend that you submit a Debian bug report so that the Debian
maintainer can try to recreate the problem. We work together fairly
closely, so once he has the problem I'll help
him to identify a fix.
