The steps below have provided considerable progress, but I have two new
problem areas:
1. Is there any way of changing the size of the LayerViewPanel to a
specific size programmatically. This would be useful to re-paint
the panel off screen at a required scale, without scaling the
styles (fonts, line widths etc)? Currently I am limited to
scaling the graphics within the printing modules, thus scaling
everything.
2. I also have problems with feature labels being rotated
incorrectly, and sometimes printed as though mirrored. The screen
display is OK, it only happens when my printer module causes a
repaint by the RenderingManager. This also happens when landscape
page format is chosen. Seems to happen when the rotation angle is
clockwise.
I did note the reference to the group planning a printing extension
(http://intevation.de/geospatial/index.en.html), but I have not been
able to access their web site today.
On an unrelated matter:
I also note some problems with setting attributes using the Change
Styles dialog - it appears that when you set one parameter, another one
is unset!!!! Has anyone seen this behaviour??
