Hi Gavin, in 2.7.x there is basically no way to have channel selection and transparency at the moment.
In 2.8.x it _might_ work, but completely untested I'm afraid, assuming you do enable jai-ext. If you have a 2.8.x release try adding -Dorg.geotools.coverage.jaiext.enabled=true as a startup parameter of the java virtual machine. Let us know how that works Cheers Andrea On Tue, Oct 13, 2015 at 12:36 PM, gavin.montgomery < [email protected]> wrote: > Hi All, > > I have an image mosaic that I can successfully use footprint management to > remove black space. > > When I use a different style to change the band combination of the image, > the footprints are no longer being applied.
