[comp.sys.atari.st] 24bit -> spectrum

dkoski@cs.arizona.edu (David A. Koski) (06/14/91)

Does anyone know where I could get source code for somthing
that will convert a 24 bit (or 8 bit, or even 9 bit) image
to spectrum format?

Thanks,
David Koski

Thanks to everyone who replied to my query about converting to
spectrum format.  The route I ended up taking was converting my
24 bit image to an 8 bit gif file and then converting that using bgif.

The down side of this is the time required.  I am doing raytracing on
my Next and this usually takes 20 seconds to 2 minutes (for a 320x200
fractal landscape image).  I can convert the resulting 24 bit image to
gif in under a second, but it takes bgif quite a while (I didn't time
it, but I would guess 2 minutes or more) to convert to spectrum.  I
then use dslide to view the pictures.  I have gotten really excellent
looking results.  I can view the pictures on my Next, but only in shades
of gray, it is nice to see them in color too.

Oh yeah, the raytracer on the Next is Rayshade 4.0, and I use the
Utah Raster Tooolkit to do the image conversions for the ST.
