[Geotools-gt2-users] colorModel

[PAUL P. <pau...@gm...>]

Hello,

I Try to display a GridCoverage2D as a bufferedImage with custom color map=
=20
(or at least custom ranges of colors).The GridCoverage source is a=20
mono-banded raster with float values - a "real world" coverage.

When i build my GridCoverage, i define Categories in my=20
GridSampleDimension[] with colors and numberRanges in each one.
Then I use the non-geophysic version of my coverage, and get the image in=
=20
order to display it in a frame.=20
My problem is that i never see my colors, but a default rgb scale.
It is the same with the GridCoverageTest (in GT2.1rc0 test Module): running=
=20
the example I get a colored image, but it seems to be the file's color mode=
l=20
and not a custom IndexColorModel.

Is it really possible to associate specific color and float values from a=
=20
mono-banded raster in Geotools?

Thanks a lot for your help
