I do a LOT of "scanning to vector" in my Graphic Advantage system.(draw my own clip art)
My question is

oes the default of "3 pixels to be removed" make for a sharper image as compared to a larger setting of say 5 pixels to be removed????
I am striving to improve my print outs,with the least amount of clean up possible!!
I usally just let it fly,then hand cut the clean up with an exacto knive!
Any help would be appreciated.

Hey Pat,

Removing more will help to filter out any trash around an object, but it may also affect the object. I have scanned at 30 before and it worked fairly well. I think the best thing is to try it at different settings and see what works best for you.

I know this isn't really much help, but since it was you I HAD to at least answer.

Wanna help me make a water tower look like a baseball??? I have a bid in for it but don't really expect to get it.

BTW The wagon is still white. heh heh

Thanks Don. I haven't tried going up that high on the pixels yet,and knew in my heart it was a matter of experimenting.I will give it a try to see what works best for me!
Time scheduel will be a factor on your water tower.
Got a 40'x140'wall mural end of August,with the Harvest 2000 meet to attend in the begining of Sept.

That particular setting will not sharpen up your image edges. That setting is for eliminating background garbage. Most scans produce a few stray pixels here and there. Kick up the contrast on your scan and you'll really increase the clutter.

That setting will remove any group of pixels within the size range you specify, that are alone in a group. So if your artwork has a small detail that contains a total of 30 pixels, and you set it to remove 30 pixels, you will completely eliminate that part of the art.

The only way to get a cleaner vector image is to scan at a higher resolution, (this produces very large files though) and go in and clean up the edges by adding and deleting individual pixels.

Remember, your resolution is DPI, dots per inch. Scanning at 100 DPI produces 100 pixels in a square inch, so at 300 DPI, you have 300 smaller pixels in that same square inch which produces a more detailed cleaner edge but also adds more background clutter.

Hi Pat. Like you I also use the "scan to vector" feature quite a bit. I usually just leave the setting at 3 pixels, and when the vectorized image comes into "composer", the first thing I do is to "ungroup all". Then I select all parts of the scanned image that I wish to keep, so that these show up as black lines on-screen. Once that is done, I simply "delete" all other objects appearing as red lines. Then, select all, shape, group, and your image should be relatively clean, with most "clutter" eliminated.
