Hi everyone,
back in 2010 I did a bit of work to help improving the raster support
capabilities of OpenJUMP (basically to add support for ESRI ASCII and
Floating Point grid formats).
Now I may have the resources to go further on with raster support by:
- adding a tool to query raster values (po

Dear OJ developers,
after a break (of a few years...), I'm back on OJ development, still
focussed on raster management and close to be ready to make available to
the community an improved version of the "raster color editor", allowing
the use of ramps, intervals, single colour values...

Hi Michaël,
I've done some tests on memory usage and, as expected, the memory
footprint increases if the Raster variable is non-static. I tried
loading 4 rasters, 2 esri ASCII grid, 1 esri FLT grid and 1 tif, all of
them having 4728 columns and 5815 rows. The memory used by OJ went from

Dear OJ developers,
still working on OJ's raster handling features: we've modified the
"Feature info tool" to make it able to display the values of the rasters
loaded in OJ. I added a third pane (called "R") to the feature info
tool, with a table displaying, for every raster, the value at the

Hi everyone.
We've tried to add some more raster-handling features to OpenJUMP, in
detail:
- Overview handling (read only) for TIFF files. External (.ovr file) and
internal overviews are now handled to speed up reading/displaying time.
The .ovr file can be created using GDAL or ArcMap. In ad

I will check the problem with "Extract part of image", thank you for

Hi Peppe,
I've managed to track down the cause of bug #386:
"ExtractSelectedPartOfImage works fine with TIFF or PNG raster files but
it fails to work whenever I try to extract a part of ASC or FLT monoband
raster.".
With regards to bug #387, what do you mean with "RasterImageLayer class

I fixed an issue related to single-band PNGs.
With regards to JPGs, I can load with no problem in my Windows machine

see should be related to JAI: in snapshot 4090 the read operation was
made using ImageIO.read, w

It appears to me that the issue is due to the fact that
