Hey Peppe,
about GIFs: I discovered (late, my bad) that GIFs use the
IndexColorModel. I therefore adjusted a couple of methods (in
RasterImageLayer and ExtractSelectedPartOfImage) to account for this
type of images. It should be ok now, have a look at my latest commit.
a) FLT/ASC: yes, I've added the methods to write these formats, although
they could be improved in terms of efficiency and implementation, so if
you have better code it's very welcome! XYZ ASCII shouldn't be a problem
to implement, while Surfer grid is a format I don't know.
b) I sometimes find the Raster>Pixel inspector very handy, because using
it is very immediate: you click and see the pixel value right there,
without the need to look at the Feature info dialog... So I personally
wouldn't ditch it. Maybe it'd need a different icon, to distinguish it
from the Info tool?
c) Sure I agree with including the symbology plugin into OpenJUMP. I
believe it would then be also nice to add support for multi-band rasters
(I'm thinking for instance of Landsat images and false-colour
composites...)... And saving the raster symbology into the project would
be awesome...
Till soon

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

Hey Peppe,
I've commited some changes that should fix most of the issues. I
don't know how to solve the problem of the GIF files being read as
monoband: it's something related to javax.imageio classes, I'lll
see what I can do.

Loading, saving extracting parts of monoband raster is fine.
Problems come with multiband files.

Peppe,
I fixed an issue related to single-band PNGs.
With regards to JPGs, I can load with no problem in my
Windows machine all the samples you attached to your mail.
Nevertheless, the problem you see should be related to JAI:
in snapshot 4090 the read operation was made using
ImageIO.read, while in snapshot 4283 is made using
JAI.create("fileload", ...). I've now modified the code so
that ImageIO.read() is used first, and JAI.create() only as a
fallback if ImageIO fails. The weird thing is that in r4283
JAI is however used to load TIFF files, but it appears that
you can load them no problem...
Since I cannot reproduce your error, before committing I'd
like you to test these changes. Could you please download
this
<https://www.dropbox.com/s/fexjyucup49hihn/OpenJUMP-0.0.0-rnull.jar?dl=0>
OpenJUMP.jar, replace it to the one you have in snapshot 4283
and tell me how it behaves?
Thanks
Alberto
