Progress with Printing Extension:
1. The reshape() method is depreciated, I have tried using
setBounds() on the LayerViewPanel(). While the bounds are changed
I cannot get the map to repaint (correctly) using the new bounds
- any thoughts?
2. The issues with the incorrectly rotated labels is a problem with
JDK1.6, the latest release (Update 1) seems to solve the problem.
3. I have placed a beta version of the JumpPrinter extension
(including the source) at http://www.cadplan.com.au for
review/comments/feedback. It is still rather basic - more work
needs to be done to add "furniture" (scales, legends, etc), but I
would like to resolve the scaling problem outlined in (1) first.
Other issues:
1. In the Change Styles dialog, if you set the Line Pattern to Style
1 (a dotted line), then OK, the line pattern is set, BUT when you
re-launch the Change Styles dialog, the Line Pattern is <blank>
(and thus set to <default> on OK). This seems only apply to Style 1.
2. I not also, that if there are two extensions to load from the
..lib\ext folder, only the first one loaded appears in the splash
screen.
