Mac -> Bit Stream Raster

[Steve]

Does anyone out there know of a utility ( on the mac or Unix ) which
can convert some Macintosh image format ( PICT, TIFF, GIF, etc ) to
a bit stream raster.

Currently, the best way we can do this is by using gif2ras on a sun
and then a BRL-CAD utility sun-pix to convert that into straight bit stream.

All this transfering of files and processing takes way too much time.
Anybody got a better way?

Thanks much in advance!
