Description
Returns the zooming factor to use for best fit a SourceSize size bitmap into the DestinationSize rectangle.
The returned zooming factor defines the scale, which can be used to fit a source image having the size = SourceSize into a rectangle having the size = DestinationSize. This zooming factor guarantees that the whole source image is totally embedded into the DestinationSize rectangle.
