[Geoserver-users] Strange borders appearing when rendering rasters with negative No_data

[Ghelli R. <Rob...@eu...>]

Hi all,
When rendering a geoTiff the borders of the layer are strangely colored although there is no data.
This happens when:
Layer is a GeoTiff, type Float32 and No_data is set to a NEGATIVE value. In this particular case the wrong border appear with the color related to the value 0 of the style used.
Geoserver is 2.5.1 using JAI. I've tried to reproduce the problem in a Geoserver installation (2.4) without JAI and in this case it not occurs.
Also if I modify the layer (using GDAL commands) setting NODATA=0 the problem don't occur anymore.
Do you have any suggestion about how to solve this matter?

Cheers

Roberto
