Support getBandInformation in PILFileTileSource

See original GitHub issue

It would be great if PILFileTileSource could implement the same getBandInformation as GDALFileTileSource. For example, I want to extract general band info from a JPEG image. rasterio lets me do this (though it throws warnings), but large_image does not. Well really, I just want to know the “interpretation” of each band (not any stats) and that’s all that rasterio will return.

Could PILFileTileSource implement getBandInformation in a way that simply returns the interpretations? e.g. “red”, “blue”, “green”, “grey”, etc.

Indeed. You’d have to know that mode maps to the bands in the PIL. getInternalMetadata is the catch-all for known metadata. As another function that is the wrong choice, the histogram function returns a histogram per band (so the length of its output would tell you the number of bands).

I’ll get to this soon.
