Replying to dmisev:

what about new style format parameters?

in metadata tag of tiff is correct from coverage which has 3 bands and each band has different no_data value.

NODATA_VALUES=100 12 23
resolution=1

Image Structure Metadata:

INTERLEAVE=PIXEL

Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0, 100.0)
Upper Right ( 100.0, 0.0)
Lower Right ( 100.0, 100.0)
Center ( 50.0, 50.0)
Band 1 Block=100x27 Type=Byte, ColorInterp?=Red

NoData? Value=100

Band 2 Block=100x27 Type=Byte, ColorInterp?=Green

NoData? Value=100

Band 3 Block=100x27 Type=Byte, ColorInterp?=Blue

NoData? Value=100

  • Resolution set to wontfix
  • Status changed from new to closed

Ok, I'll close it as wontfix as old style format parameters are deprecated.
