Hi.
I have several bitmapped fonts in small sizes, mostly a 7 by 9 character
in a 9 by 12 box.  When I scale this font UP via bit replication in X
and/or Y direction I get very ugly characters the bigger they get.

Is there a way to dynamically scale up a bitmapped character with
smoothing of all rough corners?

I have got the Hershey fonts but they are vector fonts and I don't
have the hershey.doc that was supposed to have come with the distribution.
Can anyone mail it to me?  Thanks.

Also.  If I have a color pallette of 256 entries, is there a 
standard/good order in which different colors can be assigned
to each entry.  This especially applies to mandelbrot type
images, I need to know which colors need to be assigned to which entry.
(A pixel in the graphics bitmap is an index into color pallette table).
I would also like to take an image generated by posted 'tracer' program
and dither its 8 bit per pixel output to 4 bit per pixel output and
again I need to know which colors to assign to which of 16 entries.

Any help on above is appreciated.
Thank you.
