Perhaps we should keep these changes in a separate branch of the SVN
and run/try a seperate build for a while?
I would personally like to keep the core as lean as possible. Can we
add the needed classes via a plug-in instead?

Hei all,
I have started working with Sextante, the raster processing library
(within my university project). It is possible to use Sextante external
from OJ (i.e. it comes with its own GUI) and Sextante utilizes the
new/old Pirol RasterImageLayer class to transfer raster data. However,
it can also use OJ VectorLayers as input.
Now I wanted a function that creates points/polygons out of an input
raster, which requires some basic access methods to rasters. As I am a
lazy (or clever?) person I have copied the Sextante base classes into
OpenJUMP (and renamed most of them), so that
i) one can perform basic operations on Pirols RasterImageLayers and
generate new output layers
ii) one (probably) can create portions of new Sextante algorithms
directly in OpenJUMP and later need only to adapt the class names when
converting to a Sextante processing algorithm.
possible negative aspects:
iii) doubling of code between OJ and Sextante (not sure, but I hope
there won't be much updates to the Sextante base classes/interfaces)
iv) I could have tried to use only functions provided with Pirols
RasterImage class (However, Sextante provides a nice set of convenience
methods, and seems to be very well designed).
The following classes would be added to the OJ core:
path: org.openjump.core.rasterimage.sextante.*
AbstractSextanteRasterLayer = AbstractRasterLayer
ISextanteDataObject = IDataObject
ISextanteLayer = ILayer
ISextanteRasterLayer = IRasterLayer
OpenJUMPSextanteRasterLayer = OpenJUMPRasterLayer
path: org.openjump.core.rasterimage.sextante.rasterWrappers*
GriddCell
GridExtent
GridWrapper
GridWrapperInterpolated
GridWrapperNotInterpolated
Any comments on this?
Note, I would like to have feedback until the beginning of next week.
