Hi!
After
r3 - readGDAL(test2.tif)
test2.tif has GDAL driver GTiff
and has 256 rows and 256 columns

Sorry, can't find such a posting - maybe my search keys were wrong - you

The file test2.tif was made by

I really cannot understand, Qgis uses gdal for writing and reading geotif files
as far as I know.
I think the point is that QGIS reports the origin in the NW corner and then uses
negative resolution for Y. But do not understand the discrepancy in
