Motivation
We are getting datasets that have other datatypes than float32 that need to be expanded into 4 band RGBA so basemaps can render them.
A common type is a one band
uint8which is generally a grey scale dataset which can be directly band expanded from0tor:0, g:0, b:0, alpha: 255and255tor:255, g:255, b:255, alpha: 255Modifications
Added support for
uint8anduint32with the tiler piplinesTODO: it would be nicer to handle the datatypes more generically, to hopefully avoid giant switch case statements, we should in theory be able to trust that lerc gives us the correct typed array for instance.
Verification
Added unit tests and rendered it locally
