I'd like to show the resulting images in my notebook, but if I simply use ListDensityPlot the Notebook becomes unreasonably large (many tens of MB), and can cause problems. I'd be quite happy to show the images as bitmaps, and expected to find an option that would produce bitmap rather than Postscript output.
You may want to consider redefining the Kernel's low-level display
function to achieve your objective:
$DisplayFunction :=
(Module[
{mgfstr, bbox, base, imgsz},
{mgfstr, bbox, base} =
(
LinkWrite[
$ParentLink,
ExportPacket[
Cell[
GraphicsData[
"PostScript",
DisplayString[#]
],
"Graphics"
],
"MGF"
]
];
LinkRead[$ParentLink]
);
imgsz =
Map[
(Subtract @@ Reverse[#]) &,
Transpose[ bbox]
];
CellPrint[
Cell[
GraphicsData["Bitmap", mgfstr],
"Graphics",
ImageSize -> imgsz
]
]
] &)

You can find much of the tokens by examining the contents of the files
named MenuSetup.tr that reside in this directory:
<path to Mathematica installation>/SystemFiles/FrontEnd/TextResources
and its subdirectories.
You can also find a list of tokens with explanations in the book
_Beginner's Guide to Mathematica Version 4_ by Glynn and Gray.
