Re: Graphic Formats

Tom,

I understand what you're saying, however, the files I'm referrring to were
scanned at 72dpi and then brought up into an application that supports WMF
(as well as other formats) and saved as a WMF.

If the original file was not "created" as a vector graphic, but just saved
(or, if you will, converted from a raster to WMF), then no matter what you
do to it, it remains "low" resolution. You cannot make a vector graphic
just by saving it as a WMF/EPS. Hence tracing programs, such as Adobe
Streamline, or bringing in a raster graphic to Adobe Illustrator and then
manually tracing the original to "create" a new file as a vector image.

I believe there is a conceptual disconnect here.  Vector formats
are "resolution independent" in that they will scale according to
the size you want.  Scanning cannot result in a vector format
because it generates a file made up of pixels, not vectors, which
are mathematical constructs that tell a computer where to draw
a line, how thick to make it, and if it should curve or not, be filled
with something, and so on.

(Not posted to list, but you can quote me if you wish.)
