SimpleRenderer (jump-b3p 6.0 API)

java.lang.Object
- org.locationtech.jts.jump.workbench.ui.renderer.SimpleRenderer

All Implemented Interfaces:

Renderer

Direct Known Subclasses:

GridRenderer, ScaleBarRenderer, SimpleFeatureCollectionRenderer
```
public abstract class SimpleRenderer
extends Object
implements Renderer
```
Advantage over ImageCachingRenderer: no cached image (typically 1 MB each). Disadvantage: must redraw image each time (slower). Classic tradeoff between space and time.
