We have just purchased the geocompressor and need to change the Null Band Value from Min Band Value (default) to Max Band Value. However the option is greyed out / disabled on the Opacity Channel Options.
2nd question if no answer to first: How do I get support directly from Hexagon? I see references to support tickets but cant navigate to the correct page.
Thanks in advance,

For support ticket, go to community http://community.hexagongeospatial.com/, and click "Knowledge & Support->Support portal" (https://hexagongeospatial.force.com/supportportal/s/). Login and you should be able to create ticket there.
For change NULL data value from min to max, I don't think you can do it in Geocompressor. I know user can use ERDAS IMAGINE metadata to change NULL data value. You can check the following KB:

Thanks for the quick reply hauyan_qu! I have forwarded it to our ortho tech for him to try.
Additionally, Hexagon support has contacted me and opened a ticket on this issue.

You can only change the null band value if the output format is ECW version 3 and the compression method parameter is set to “Tile”. If you are outputting to JPEG2000 or ECW version 2 the option to change the null band value is disabled.
