Hello,
You got the point!
I used the prepare-method to create the OMGraphics because i thought it
is only called once at startup.
I debugged my program and saw new OMGraphics being placed with every
change of the projection. Meaning with every zooming or moving of the
map, my OMGraphics were placed again.
I am now checking for that object does not already exist in the
graphics-list before adding it.
Much thanks for that hint, you saved me a lot of time!

Sounds like the icon is being added to the layer after each paint. Is
it possible you're adding multiple omgraphics at the same position and
icon?

CC: [OpenMap Users] Transparency of OMGraphics - bug?
Hello,
I've got a problem with OMGraphics as follows:
When adding an OMGraphic to a OMGraphicHandlerLayer, having a
transparent fill-color, the transparency is decreasing over time when
projection changes (zoom in/out or move the map).
For example a OMCircle with the fill-color yellow and an opaqueness of
15 (int) is added to a Layer. Layers underneath the circle can be seen
and get a little touch of the circle's yellow. Then zooming a few times
will result in a more and more opaque circle until no transparency is
left.
For setting the color i tried java.awt.Color and
com.bbn.openmap.omGraphics.OMColor. Both with the same results.
I use the following code:
OMCircle testCircle = new OMCircle(0.0, 10.0, 20.0);
testCircle.setFillPaint(new Color(255, 255, 0, 15)); //
with 15 being the opaqueness
testCircle.setSelectPaint(Color.YELLOW);
testCircle.setLinePaint(Color.BLUE);
graphics.add(testCircle);
I'm using OpenMap 5.0.
Does anyone know about this problem or how to solve it?
Thanks in advance for any information or help.
