Re: [Geoserver-users] Has image mosaic InputTransparentColor behaviour changed since 2.0.1 ?

[Daniele R. <dan...@ge...>]

Hi Ivan,
did you set the HandleFootprint parameter to false?
2.0.2 relates on 2.6.4 which provides support for footprint (Essentially, a
shapefile providing data validity area for each granule composing the
mosaic). When using it, each granule is cropped on its footprint borders
before doing the mosaic. Therefore, there is no more need to mask a
"white-fill" or a "black-fill" or an "inputTransparentColor-fill" to exclude
the granule's void area to mosaic it.
I have tried your sample data on 2.0.2 by setting the parameter to false and
it works fine.
Please let me know if you can confirm this.
I agree that maybe we can setup the default value for this parameter to
false.

Regards,
Daniele
