[comp.sys.mac.hypercard] HC 2.0 picture XCMD problems

G.A.Hutchings@ecs.soton.ac.uk (Gerard Hutchings) (10/10/90)

I am having problems with the picture XCMD in HC 2.0.

With my IIci in b&w mode, the sample pelican from the Power Tools
stack looks terrible - there is no attempt made by HC to dither the
image, and nothing like "set the dithering of window pelican to true"
seems to make any difference.  On an SE however, the pelican looks
fine - in b&w of course.

When I display my own PICT image from Applescan - 4 bit greyscale - it
looks fine on the IIci, once the dithering has been set to true.
However, on the SE it looks bad - just like the pelican on the IIci in
fact.

So my question is this: why do the two images behave differently ? I
would expect them to behave as my PICT image does, but the pelican
seems to have a mind of its own!

Is there something really obvious that I'm missing ?
