Hi,
I forgot to mention that the problem occurs when reprojecting the layer from
EPSG:32632 to EPSG:3857.
After doing some tests with the SLD style I can confirm that the wrong edge
color is the color used for values=0 (if the value=0 as opacity=0 the wrong
edge is not displayed).
Regards
Roberto

Subject: Strange borders appearing when rendering rasters with negative No_data
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
