<p class="MsoNormal"><span style="">I’ve got a
question about rotating (with angle/angleitem) a truetype font symbol.</span></p>
<p class="MsoNormal"><span style="">I’ve
created a layer that shows bridges etc. of roads. I’m using a font that has a ‘bridge-symbol’.
The direction of the nearest road in angles is stored in a attribute of the bridges-data.
It works fine with pixmap symbols. When using truetype font symbols and the
angle is 0 it also works fine. But when the angle is getting bigger the symbol deviates
more from the real point. The symbol is rotated fine. I think this has to do
with the point of rotation of the truetype symbol. In pixmap’s the point of
rotation is the center that’s why it works fine. I’m using a truetype font
symbol because I want the symbols fully transparent. When the pixmap symbol is
rotated it isn’t transparent anymore. I thought this was a good solution….. Can
anyone help? My ‘code’ in the mapfile: <br></span></p>
