Until recently there was no color image operator in PostScript.  Adobe
added 'colorimage' to display PostScript and also to level 2
PostScript.  Several color PostScript printers have already adopted
this operator.  Presumably your scanner uses 'colorimage'.
Unfortunately NeWS predates 'colorimage' and has its own extension to
the 'image' operator to handle color images. It doesn't support
'colorimage'.

You best bet is to scan it in Sun rasterfile format, copy it to the IRIS,
and use the fromsun translator in 4Dgifts to convert it to an SGI .rgb. file.
You can then use izoom to shrink it to 100x100 for pandora.
