Hi Alberto,
I tested this new OpenJump.jar, using RasterImage Layer class. I did a
large test to check also the other file formats. I listed below the results
*Loading multiband files: *
1) JPG, OK
2) PNG, OK
3) TIF, OK
4) GIF. Only one band is loaded, It seems to me band 0 and the image is
displayed as B/W
*Loading monoband raster*
1) TIF, OK
2) ASC, OK
3) FLT, OK
4) PNG, OK
*Saving multiband files as TIF*
1) save JPG to TIF Null point exception
java.lang.NullPointerException
at
org.openjump.core.ui.plugin.layer.pirolraster.SaveRasterImageAsImagePlugIn.execute(SaveRasterImageAsImagePlugIn.java:131)
2) save PNG to TIFF, OK
3) Save TIF to TIF, OK
4) Save GIF to TIF, OK (Saved file is monoband , as the displayed)
*Saving monoband as TIF*
1) TIF, OK
2) ASC, OK
3) FLT, OK
4) PNG, OK
*Extract part of selected image (monoband files)*
1) TIF, OK
2) ASC, OK
3) FLT, OK
4) PNG, OK
*Extract part of selected image (multiband files)*
I had problems. All extractions failed with a error message. I listed below
all these messages
1) *JPG,* java.lang.NullPointerException

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