the resulting vector image should resize without alias issues.
Now that's interesting Kglad. I tried these settings first:
Color Threshold: 80
Minimum Area: 1 pixel
Curve Fit: Pixels
Corner Threshold: Many Corners
I wasn't able to set the color threshold any lower, because it caused Flash to freeze. The text rendering is now excellent and file size reasonable. The art/images on the page have problems I'm still puzzling with.
if you need higher fidelity walk away while flash is working with the higher settings.
it can take several minutes for flash to render the vector and respond so if you need higher fidelity and can tolerate increased file size, be patient. i've never had flash lock up indefinitely. it may return an out of memory of some such message but it i've not had to restart or cancel the conversion process.
That makes sense; I've had Acrobat show the "not responding" message while trying to save unusually large files. A minute or so later and the file is saved and message gone. On almost any other software vendor's product, "not responding" means go into Task Manager and kill the process. Thanks again.
