That does help, and I have been looking at #1 today. However, I
noticed there does not appear to be a 1 to 1 relationship for
Renderers to Layers (in my case anyhow). For example, the same
georesource URL for my shapefile seems to be mapped to both a
TiledRenderer and a BasicFeatureRenderer (both are returned by
getRenderers()). This may be elementary, but it's not clear to me
why this is or which one I should use to actually obtain an image of
the shapefile.
Thanks,

There are 2 ways right now.
1. The renderer API has a render( graphics2d ); method that will
render that layer to the graphics2D object. You can get a renderer
from the RenderManager.getRenderers(). You can create your own
BufferedImage. Create a graphics2D from it and render to that
image. This is the recommended method.
2. The second way is to call renderer.getContext().getImage().
For this version and the previous version this will return the last
rendering of the layer. But this is not guaranteed to do so in
future versions. We have has some complaints about the amount of
memory a separate buffered image for renderer takes up. So we will
probably add different configurations that do not do the caching.
Hope this helps,

I've been getting the raw Image object (BufferedImages) from Maps for
use in export to other mediums.
Is there a way to get images of individual layers (e.g. if I have a
shapefile layer and a raster layer, and I want the image of the
shapefile layer only)? As a workaround, I can create separate
maps for
each layer, but that is not ideal.
Thanks!
