[Gdal-dev] XResolution tag in GeoTiff

[Gérald CLETTE]

Hi

I developped a new driver based on the GDAL data model to handle a new
format with the gdal_warp tool.
Then, I tried to create a GTIFF product but the new file didn't contain the
XResolution, YResolution nor ResolutionUnit tags. I thought that these tags
were not optionnal in the GeoTiff description.

My question is : Is it a bug in the Geotiff library ? Or how can I manage to
product a "full" GeoTiff product with gdal_warp ?

Thank you for your answer.
