| RE: [udig-devel] Difficulty with raster images using World Image Files |
|
Basically, I have written a icon group manager dialog where users
can create their own groups of icons which are then displayed in a tabbed pane,
on for each group, in a View at the side of the
map. So the first I know about it is when they drop the icon
onto a map.
I am
not sure if I understand exactly how an sld works yet. If there is one
sld file per shape file(?), then I guess I have to create a new one for each
layer from my code - just string write it out to a file on the drop of the first
icon of that type when I create the new layer/shapefile, with the icon path hard
coded - assuming the External Graphic can be a local file reference and not
just a web address?
Is
this my only choice? If so, I can go ahead an code for that.
