Dear Peppe and Others Interested
I have just posted the lasted version of my VertexSymbols plugin that
now supports symbol rotation based on the value of a selected numerical
valued attribute (assumed to be in the range 0 to 360 degrees). It
also requires an upgrade of my JumpPrinter plugin to the latest version
if it is being used concurrently.
I have not resolved the issue surrounding the use of SVG fonts.
Font-based symbols can be turned into SVG images by installing the font
on you computer, then using a suitable drawing tool (I have used MS
Visio successfully) create drawing elements from the chosen
letters/symbols and save them individually as SVG image files. These
can then be imported by the plugin, rescaled and rotated as necessary
and used as symbols of vertices.
Please advise of any problems.

Geof and Ravi,
I think I found a solution about question: how to
rotate symbols according to an attribute value.
This solution doen't require extra plugins. I only us
the label style function of Openjump
1) I instal my font symbol (Geology.TTF). I have
printed a reference table that show me the
corrispondence of each symbols to regular alphabet
("a" is symbol 1, "b" is symbol 2, etc)
2) I use a point dataset with two attribute values:
(TYPE_SYMBOL) one for the type of symbol, for each
symbol I give the regular letter of the alphabet (a,
b, etc).
(ANGLE) A second one is for angle attribute
3) on Change Style>label>enable labeling
label attribute = TYPE_SYMBOL
angle attribute (degrees) = ANGLE
on Change font ... I choose my geology.ttf fonts
And magically I see my geological fonts on the
workbench view
I can choose colour and dimesions of these "point"
symbols. I can't choose a label for them. But I can
use a duplicate of the point layer as a label layer.
Now I am working to a special set of font with a
regular corrispondence to the alphabet.
By the time I am ready I will post all for users
@Geof
Are you working on the same idea?
I am drawing the new version of the fonts with
Inkscape (SVG), do you know a way to import them as
SVG fonts and the as TTF fonts?
@Ravi
Together with this mail I post the most common
geological fonts that people can use. You can see them
and send me an idea about other symbols I can put on
the font set
Peppe
