Hi all, When I import an image (say FITS) with A = Import["file.fit", "FITS"], the image shows up quickly in Mathematica 6.0.1. That is good. I wan to process the raw pixel data so I load it into P by P = Flatten[Import["file.fit", "RawData"],1]. Now I want to see the result. ListDensityPlot worked fine in 5.2. However, when I call ListDensitPlot[P, Mesh->False] in the latest version of Mathematica, it quickly consumes all available RAM (~1.5Gb), and the computer starts swapping which forces me to kill the process. I'm not talking about huge images. 640x480 or so. Clearly, there must be a way to show a 640x480 density plot in Ver. 6. Any suggestion? Thanks, Laszlo
