GIF is not vector based. dots.
DWG is vector based. data. a data base.
a DWG circle is a database entity with a centerpoint, a radius and other
data controling layer, color, linetype, etc.
a GIF circle is dots. they may or may not all be an equal distance from
some mythical center point, which may or may not have a dot......
I guess what I am trying to say is the thought "convert" is misleading
at best. there is data needed for a DWG that a GIF simply does not
contain. any REAL SOPHISTICATED program that GUESSES for you about the
missing data is still just guessing.
garbage in, garbage out.
if your dots all line up with something near a mathmatical precision,
your program might well create a vector line from it. if your GIF was
created from vectors in the first place, with HIGH RESOLUTION....

GIF is just a file format. says NOTHING about the actual work that would
be needed to take a abstract group of dots and create an abstract group
spit in one hand and wish in the other and see which one gets full first.
