Dear SS and Developers
I used the existing WKTFillPattern class for the WKT petterns, all I had
to do was to load the WKT spec from the designated folder. For the
image patterns, I found I had to implement a new renderer as the
built-in class ImageFillPattern seems to require the IconLoader class to
load the images (and I haven't figured out how to change the path for
the image files away from the package location to the plugins folder so
it is accessible to the user). If there was an option in IconLoader to
specify and absolute path for the images then I could have avoided this.
There are still a couple of problems, however:
1. When the new patterns appear in the Fill Patterns combo of the
ChangeStyles dialog, they get a 0 index number. As far as I can
tell these index numbers are hard coded by the built-in list of
patterns. This does not appear to case further problems.
2. In my PrinterPlugin, the "Quality" rendering option sometimes
fails as shown below. This option uses the
RenderingManager.copyTo() to copy the image to the current
graphics context (to be use for printing). This rendering option
also produces getBounds() (No yet implemented) errors from
PolygonShape(). The "Accurate" option uses the LayerPrinter2()
class that creates a new LayerViewPanel does not have this
problem, also the external renderer is fine.

Very cool Geoff! I like the idea of being able to specify custom
vector fill patterns using WKT. I bet the designers of the spec never
imagined it being used in that way.
Perhaps I will have time to check your plug-in out this weekend.

P.S. - Did you have to implement custom rendering behavior to create
this plug-in?

To Open Jump Users (and Federico)
I have just posted a new plugin for OpenJUMP that allows users to to
create their own fill patterns. Fill patterns can be vector based using
a WKT specification, or image based using GIF, JPG, PNG or SVG image
files. Image files are loaded by the plugin from the FillPatterns
folder within the plugins folder.
The new fill patterns appear in the Fill Pattern combo (added to the
bottom) of the Change Styles dialog.
Details can be found at my web site: http://www.cadplan.com.au
This is still a preliminary version, so comments and feedback are
welcome.
