Hi All,

Does anyone know how to get normalised value of ViewPortHeight. Multiscale image has other properties which I tried to calculate the height such as image.ViewPortWidth/image.AspectRatio, but I beleive it is not the correct way.

There is’nt any documentation on it as well. Please can someone advise.

Thanks
