- Color compositing and color blending
- ====================================
- It is possible to perform color blending and compositing, either between feature type styles or by associating blending operations with each symbolizer.
- GeoServer implements most of the color compositing and blending modes suggested by the `SVG compositing and blending level 1 specification <http://www.w3.org/TR/compositing-1/>`_. Either set of operations allows one to control how two overlapping layers/symbols are merged together to form a final map (as opposed to the normal behavior of just stacking images on top of each other).
- This section will use the following definitions for the common terms "source" and "destination":
- * **Source** : Image currently being painted *on top of* the map
- * **Destination**: *Background* image that the source image is being drawn on
