How do I mimic GeoImage.CopyColorTable in gippy 1.0?

[ra-tolson]

We're trying to migrate gips from gippy 0.3 to 1.0, and it's not clear how to duplicate GeoImage.CopyColorTable. I can almost mimic it by looping over the bands and doing GeoRaster.add_colortable, but I can't figure out how to get the colortable out of the object I want to copy from. I think GeoRaster._GDALDataSet.GetColorTable() (or similar) would do it, if outside code could call that.

Is there a way to do it that I can't see, or would gippy need to be extended somehow to do this?

Hello @ags-tolson
When developing gippy 1.0 I ended up removing some functions that weren't used internally by other functions or by algorithms, or that were replaced by other things. I'll review this and if it can't be done currently I'll add the feature back into develop.

Don't hesitate to post any other missing functionality here you come across during the migration, some of it might just need to be features added back in which can be bundled into either a 1.0.1 or 1.1 (if more substantial) release.

That'd be great, thank you! Overall it's working pretty well for us in terms of doing what gips needs to do; modis is already pretty much converted and landsat is in progress. Mostly I expect to pester you about these little corner cases.

If you're curious about the details, here's a diff which should continue to update:
