My goal is to display a GridCoverage2D (and benefit from the
zoom/rotate/pane viewmenu)
[...snip...]
But I experience problem when trying to display a GridCoverage2D in a
StyledMapPane:
My code:
------------------------------------
[...]
BufferedImage bi = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
[...]
GridCoverage2D gc = new GridCoverage2D("My colored coverage",
bi,
DefaultGeographicCRS.WGS84,
envelope, null, null, null);
[...]
The error I get:
------------------------------------
java.lang.IllegalStateException: Some categories use non-integer sample values.
at org.geotools.coverage.GridSampleDimension.getCategoryNames(GridSampleDimension.java:686)
Did you tried with an indexed color model instead of RGB? I mean:
BufferedImage bi = new BufferedImage(width, height,
BufferedImage.TYPE_BYTE_INDEXED);
