other RAW converters give the specified pixel dimensions. However, in
reality there are more pixels and dcraw for instance delivers them. This
is the reason why you have different image sizes between PTGui RAW
import (which uses dcraw) and f.e. DPP converted images.
Naturally this gives a slightly different crop factor.
