Dear List,
I am using Geoserver 2.7.5. I want to create a layer out of several geotiffs so
I created an imagemosaic. The geotiffs are 32bit tifs an I want to colorize
them using Geoserver Styles. The single tifs overlap at the edges and partly
have no data values there which appear in the mosaic. To avoid that I wanted to
set the "Input Transparent Color". But when setting a value I get an Error:
org.geotools.data.DataSourceException: Unable to create this mosaic

It seems it is not possible to set the InputTransparentColor for 32bit images
which seems logical. But how can I get a similar setting for 32bit images?
Regards,
Sabine
