Hei Michael,
lets see if I can answer the questions:

correct

I think(!) we could image migrate image loaders (i.e. the ones that work
with drag and drop). The original image loader interface was contributed
by Jon (code in vividsolutions.jump). Raster loader is based on the
Pirol code.

In theory yes... if we deal with a java image at the end. But.. thats
more or less an educated guess. However, the raster image loader loads
already png, jpg, tiff etc... so it would be more about adding mrsid and
ecw.

puh.. I need to check...
so...the (new) raster code is based on the classes in
org.openjump.core.rasterimage - the main classes are
AddRasterImageLayerWizard and RasterImageLayer and
OpenJUMPSextanteRasterLayer
the image loader code is based on:
com.vividsolutions.jump.workbench.imagery, and
com.vividsolutions.jump.workbench.ui.plugin.imagery;
main class here is (I believe) AddImageLayerPlugIn
and to your first question. Mhm i would say the main difference is that
the sextante framework is more flexible - i.e. it holds an abstract
image that can be manipulated and hence, provides functions for
imag/pixele manipulation - and access to individual pixels (also new
-empty- rasters can be created), while the image framework holds
non-modifiable images/rasters and one can not access individual raster.

thanx for your input on that. Yeah the latest version doesn't require
sextante libs anymore. And no worries about all the questions ;)
now I am actually back in Calgary - for a bit (4 days).
cheers,
stefan
