We are unable to get GeoTIFFs to display. There are no errors, just no
display. We backed all the way out of our applications and created a
fresh test environment using v14 via Maven and used ImageLab as the test
program. The result is the same as we saw in our applications. The
bluemarble (the GeoTIFF) does not display. As with our application all
indications from the code are that it is working, but there is nothing painted
for the TIFF.
This issue has been confirmed by Ian Turton email@example.com. He added that it did work with single-band TIFFs he had available.
