Hello! Thank you John, this is a fantastic function. However I'm experiencing the same issues that Yongmin Jiang (May 2007) and Koos Spee (Mar 2010). Did anybody find a solution for this? I normally print my contour plots in epsc or pdf and they look very sharp and smooth and when I use freezeColors the contours and axis labels become very smudged and pixellated. This is very frustrating as creating subplots works so much better for me than individual figures. Did anybody find a solution to this? I played around with resolutions and different file formats to no avail.
