Hi Alberto,
It seems that everything is going fine, except, as you wrote, loading gif
file.
I took time to see the other job you did on OJ raster capabilities
a) some method to save .FLT and .ASC files. I was working around, with my
limited java skills, to a similar project. It is my intention to add an
"Export to grid" plugin to save to ASC, FLT, GRD (Surfer grid file 6) and
XYZ table file. The latter two options (GRD and XYZ) came out from a couple
of costumers who had to work with those two types of file.
I have the code for this plugin that I wanted to add in the next days - I
am glad to discuss with you, if you have other ideas about. - and find a
common solution
b) Now "Feature Info" Tool also shows raster cell value in a <R> panel. We
should change the name of the plugin to "Info Tool".
This option makes Raster>Pixel Inspection tool obsolete. I think we can
save this plugin, that I added two years ago, and transform as a
ArcGIS-like "Pixel Inspection" tool to query individual or areas of cells
which values can be saved in a vector layer. Even in this case I have a
partial solution (individual cells) for this plugin and your (or others)
opinion is welcome.
c) Raster ColorModels. I gave a look to your RasterStyles and RasterLegend
plugins. These are definitely more efficient than Raster Color Editor
(RasterColorEditor.class and package) embedded into OJ (Legend, pixel
transparency, etc).
I think we talked about few weeks ago - and I changed my mind.
I feel that we can add your plugin, if you agree, into OJ code.
As you wrote, It could be as panel of ChangeRasterImagePropertiesPlugIn,
Hiding RasterColorEditorPanel and adding an enablkecheck to activate it
only for single band raster.
In this case I can help you adding more color schemas (see the one I
embedded into
RasterColorEditorPanel).
Regarding RasterColorEditor.class, we can save the access under "Raster"
menu, if any user are using it. In any case there are no problems of
compatibility as ColorModels are not saved into OpenJUMP project files.
I can go on for more. I checked AdBToolbox and GvSIG code and there are
many opportunities to extend OJ raster capabilities and I am really glad
that you decide to collaborate with your java competence and interests.
Alberto, if you want, you can write me personally in Italian, for any kind
of details and information.
Best regards
Peppe
