Description

Add two layers, a shapefile and a raster layer, to the map (e.g. from naturalearth.com)

  • put the shapefile layer on top of the raster layer
  • change style for shapefile and add a label (everything is still fine)
  • change layer order and drag&drop the raster layer on top of the shapefile layer
  • borders and fillings of the shapefile are not visible anymore, label are still shown

The same behaviour can be reproduced for uDig 1.1.1.
In addition, another problem exists - labels are on top of the legend.
See pictures attached.

I guess the problem is coming from the ILabelPainter which has no information about the "paint over" between layers. In this case its the winning raster layer (which is not transparent).
From my Point of View the CompositeRendererImpl should check the style (OpacityFinder) and the resulting image from renderer whether its ColorModel hasn't an alpha value (hasAlpha == false).

The OpacityFinder doesn't support RasterSymbolizers up to now, therefor I created an issue : GEOS-4102

If the check is positive, for all (already) rendered Layers the Label Cache should be disabled.

Any other better suggestions to solve this?
