1 bit support?

See original GitHub issue

I’m trying to add GeoTiff with 1 bit per sample (black and white) and I’m getting this error:

Uncaught (in promise) Error: Unsupported data format/bitsPerSample

Thanks for any reply.

@DanielJDufour I already tried, and I ran into the issue that the CCITTRLE (Fax Group 4) compression is used in the file which is currently not supported. I tried to quick an dirty use the implementation of PDF.js, but failed to get it to work. I’d love to, but I’m out of time to do an implementation right now. I think doing a gdal_translate to use a different compression should do the trick
