Hello Dbky1,
From what I can find, it appears that Streamline does not work in the
way you think it does. The following discussion at Adobe's user to
user site
http://www.adobeforums.com/cgi-bin/webx?50@207.Lc9eaV5eBZj.2@.1de5eb21
describes the way that objects are converted. To quote...
"So essentially you end up with a black circle then a white circle
placed on top of the black circle. This is why you are seeing what
appears to be another layer."
This was in response to a user's question about how the image
"changed" (turned black) when they selected a portion of the image.
This sounds like the same symptom you are having. You may also get a
"better answer" from that user to user forum as well.
Now that I think about this more fully, it might be possible to treat
your "doughnut" as a "C" (with the edges of the C pulled close
together) to get the right effect, but I can't confirm that would
work. I can also see that it may introduce artifacts you don't want
either.
A few other good references include:
http://www.medicalart.net/pages/guides.html
About half way down it notes that white may not be transparent.
References to free (or low cost) tools that may do the equivalent
steps
http://www.tivea.net/Graphic_Utilities.html
see Autotrace, Kvec; others may be OK as well (e.g., conversions to
SVG). If one of these work, you should be able to get the converted
file back into the Adobe tools.
Good search phrases include:
streamline convert vector graphics transparent
which provided the references I provided (as well as several others).
If this does not give you a solution to the problem, please ask in a
clarification request so I can dig some more information out for you.

I appreciate it, but I dont think it is addressing my issue of
transparency, where after converting to a vector format, internal
areas of the object loose transparency that it previously had as a
bitmap object. The background area is still transparent.

Hello Dbkyl,
The point I was trying to make is that Streamline appears to handle
regions "within" the picture differently than the exterior. I am
trying to get a follow up on the user to user forum to see if this
interpretation is confirmed and find out if another work around is
possible.
Another approach I suggest to try in the meantime are the following
steps:
1. Convert one of your pictures where the external transparency is
"OK" and the internal transparency is not.
2. Preview the converted art (converted art / preview). Use the
pointer to select a part of the "external transparency".
3. Check the settings of the "Paint Style" (under the Options menu). I
would expect to see the slash mark (indicating "no fill" through the
fill, stroke and/or swatch. Note the settings for this part of the
converted picture for the next step.
4. Select a part of the "internal transparency" which is currenly
white. Make the "Paint Style" the same for this as for the external
transparency.
Repeat the last step for each part that should be transparent. Save
when all internal white spots are converted. This should give you the
result you are looking for.
I realize this can be a tedious manual process and why I suggested
looking at other tools in my original answer. If you can specify which
type of system you are using (eg., Windows, Macintosh) I can do a more
focused search on conversion programs that will work with your system.

Hello Dbkyl,
There are a number of raster to vector conversion programs available
for Windows computers. I will list a few that appear to have trial
versions (try before buy) so you can determine which one can best meet
your needs. I am also including a couple references to on line
directories that have a more comprehensive list of programs to choose
from.
Silhouette
http://www.silhouetteonline.com/
This perhaps looks the closest to Streamline. There is a Quicktime
demonstration that you can view as well as a trial version. It also
supports operation as a plugin to Adobe Illustrator.
Hijaak and Hijaak Pro
http://www.hallogram.com/hijaakpro/
A comprehensive program to convert between "over 115 graphic file
formats". I don't see a trial version available, but they indicate you
can return it for a 15% restocking fee (less than $25).
RasterVect
http://www.rastervect.com/
A CAD support program - definitely has a try before you buy version
available.
Many of the products definitely had CAD users as their primary focus.
I'll list a few of them for reference but I'd try the ones above
before looking at these.
Acme Trace Art
http://www.freefirestudio.com/software.htm
Algolab
http://www.algolab.com/products.htm
More general lists of graphic applications are at...
In the Google Directory
http://directory.google.com/Top/Computers/Software/Graphics/Converters/?il=1
(if you do a search in Google, the directory entry is often shown
below the link - that is how I found this particular category)
At About.com
http://graphicssoft.about.com/cs/bitmaptovector/
About will refer you to a few "featured" products and then provide a
more comprehensive list at the end. Some of the references are "how
to" documents as well.
I hope this answer gets you a solution that meets your needs. I will
also add another clarification if I get a more direct answer on Adobe
Streamline. Good luck.
