Hello,
Can you give me some pointers about how
the rendering is working internally?
We want to use uDig mapeditor within our
application but I need to estimate how much time it will take to fix this
rendering issue? Hopefully you can give me some more information?
Best regards,
Johan de Koning

Rendering issues
You are welcome to try. If you find a good way
please let me know and I will add the fix to udig.

Thanks for your answer. Could I make a change in the
rendering code, so that the map is not cleared between redraws after panning? I
just want to have the new image (the result of the layers) rendered on top of
the old one. Is it possible for me to made this simple hack in the code or
doesn’t it work that way?
Best regards,
Johan de Koning
We have a tiling renderer in the works that greatly
improves this but it will not be ready this release or probably not even the
next. Simply because of the complexity of the job.
Thanks for the list of bugs for editing. That is an area that is under
constant revision right now and as soon as it is done 1.1 will be
released. Right now there is major issues with moving feature that have
to be resolved before I can move on to more minor issues such as these.

Hello,
When i finish zooming or panning of a map inside
udig, the complete mapeditor is redrawn. This results in white screens between
finishing the action and the rendering of the map. I was wondering if this way
of rendering will be changed? For example when i am finish panning it should be
nicer (and also clearer to the user) that the map is redrawn on top of the
panned map so that there are no white screens between the actions.
I also noticed the labels rendering issue (and made a
bugreport of this). I found out that there are more rendering issues when you
are in editing mode. A summary of the issues i found.
* When drawing a new polygon the lines to a new point
(which is not placed yet) is not render correctly. Sometimes the line just
freeze.
* When finishing a polygon (with double click) an
extra line is rendered to the position where the double click action is
executed. This line does not belong to the polygon and should not be rendered.
* Selecting a polygon with a edit tool and perform a
zoom/pan action results in a render problem that the editor selection line
around the polygon is not correctly rendered (the scale or the position are not
correct)
I was wondering if these issues will be resolved in
the new udig release?
Best regards,
Johan de Koning
