[gdal-dev] gdaladdo level values

[Richard Nicoll]

Hi guys

I am new to using GDAL so apologies if this is a silly question!

When using the gdaladdo to create GeoTIFF pyramid layers (overviews),
can the levels values be decimal values, or do they have to be
integers?  I have tried using decimals (e.g. 4.3) since this will
produce an overview at the exact required scale for the viewing app,
however GDAL appears to be rounding up/down to the closest whole
number!

Does anyone more experienced have any advice please?

Thanks,
Richard
