I am trying to produce imagery of bathy data using IDV's
Contour2DDisplayable.
Please see the GEBO table at
http://www.ngdc.noaa.gov/mgg/image/IBCAO_GEBCO_comp_colortable_oc.jpg
I am trying to influence the Displayable so that my data is shown
according to the GEBCO scheme.
I am using
ContourLevels cl = new IrregularContourLevels( 0, 25, 50 .... 0 as per
the jpg)
displayable.setContourLevels( cl );
float[3][14] COLORS = rgbs for 14 colors as floats.
displayable.setColorPalette( COLORS );
It is not quite turning out as I expected. i suspect that the two
calls above are not as entwined as I had hoped. I note from the
javadoc the suggested use of setRangeForColor(). however is also
appears that the color palette is somehow linear in the scalar map
range?? The GEBCO scheme is not linear, but more discrete in its
binning.
Any help gratefully appreciated.

PS i hope i have not asked this before, i have trawled the logs...
