            Description

            We are currently in the process of migrating from IcePDF 4.3.2 to 6.1.3 and are experiencing major image scaling quality problems.

            We have attempted to set org.icepdf.core.imageReference=smoothScaled. We have also double checked that this is indeed the scale-type being used by the ImageReferenceFactory-class.

            The rendered image doesn't really look very 'smooth scaled' so I'm not sure what's going on.

            Is there some setting I'm missing?
