Hi,
as part of the new raster style editor for udig I am trying to style a
black and white geotiff.
My first test is to just make two ColorMapEntry to change the two main
colors to something else:
ColorMap colorMap = sf.createColorMap();
Color one = Color.green;
Color two = Color.red;
ColorMapEntry entry = sf.createColorMapEntry();
entry.setQuantity(ff.literal(0));
entry.setColor(ff.literal(one));
entry.setOpacity(ff.literal(1));
colorMap.addColorMapEntry(entry);
entry = sf.createColorMapEntry();
entry.setQuantity(ff.literal(1));
entry.setColor(ff.literal(two));
entry.setOpacity(ff.literal(1));
colorMap.addColorMapEntry(entry);
rasterSym.setColorMap(colorMap);
That would be the same as the non programmatic way add the following to the sld:
<FeatureTypeStyle>
<Rule>
<RasterSymbolizer>
<ColorMap>
<ColorMapEntry color="#00FF00" quantity="0" />
<ColorMapEntry color="#FF0000" quantity="1" />
</ColorMap>
</RasterSymbolizer>
</Rule>
</FeatureTypeStyle>
Alright, what happens is that the image that before was reading and
displaying nice, now starts freezing everything as if it was reading
everything and not just the overviews.
Can anyone with a proper insight give me some advice about how to proceed?
Also, is there a different way to just alpha a single color in a coverage?
Thanks,
Andrea
