[gdal-dev] Errors writing GeoTIFF with NBITS=1

[Schmitz, Uwe]

Hi Folks,

with gdal 2.4.0 I get errors doing the following:

gdal_translate \
   -co COMPRESS=PACKBITS \
   -co NBITS=1 \
   -co PHOTOMETRIC=MINISWHITE \
   -co PROFILE=GeoTIFF \
   -a_srs epsg:25832 \
   src.tif \
   dst.tif<CR>
Input file size is 4000, 4000
ERROR 6: dst.tif, band 1: SetOffset() not supported on this raster band.
ERROR 6: dst.tif, band 1: SetScale() not supported on this raster band.
ERROR 6: dst.tif, band 1: SetUnitType() not supported on this raster band.
0...10...20...30...40...50...60...70...80...90...100 - done.

src.tif is also GeoTIFF with NBITS=1, COMPRESS=PACKBITS etc.
but dst.tif seems to be the problem.
A search showed me that I can prevent the errors by setting:
export GDAL_PAM_ENABLED=YES

Is this intended? At least with version 2.1.1 there were no errors
without this setting.

Thanks in advance
Uwe
