Masked arrays can have their
maskattribute set tonumpy.ma.nomaskto indicate that no values are masked. If I try to reproject such an array usingrasterio.warp.reproject, I get the following error:The error comes from this line:
rasterio/rasterio/_warp.pyx
Line 382 in 7adb4f5
This pull request is an attempt to fix the issue by filling the alpha mask with
255if the input array's mask is set to thenumpy.ma.nomaskconstant.
