In my experience, the GIF filter built into Visio is Horrible!

it makes the PDF.
2. Print the Visio graphic to PDF.
3. Import the .ps file into Frame as an eps file.
4. Convert to help using a utility that understands how to convert

Trick 2 (this one worked):
1. Size the visio graphic to exactly the size you want.
2. Use Snagit to capture the image. Region capture works best.
3. Save as .gif.
I specify Snagit because I've found it does the best job of reducing
the colors of a full-color screen capture to 256 colors when creating
a GIF file. I tested HyperSnap, Snagit, and FullShot (FullShot is my
favorite for ease of use and breadth of features). Snagit did a
VASTLY superior job of color reduction. The other two created much
lower quality GIF images--especially when the captured image
contained more than 512 colors. Furthermore, the Snagit-converted
images used a palette that looked equally good in IE, IE-Mac, and
