How can I get good vector art from photos?

Post by VaderSpade »

I mostly engrave small images into aluminum (2" X 2"). There are lots of nice images out there to work with but once in a while I need to use a photo because there is really nothing else to work with.

Right now I need to get a simple line engraving from a photo of Chief Joesph.

[EDITED BY ADMIN to remove copyrighted image]

Like I said it will only be 2" X 2" so I don't need too much detail, I just need to to be recognizable.

Are there any simple tricks? Any one know of an artist that can do black and white simple line caricatures from photos?

Some of my other work.

I could try, I'm at work for another 6-7hrs though. I would do it by selecting the bitmap, turning down the fading of the unselected bitmap. Then simply drawing polylines over the image and adjusting them with the node edit option. You just need lines for engraving correct, and not closed vectors for creating shapes right? If you don't get it by the time I get home I'll give it a whirl.

Yes, just lines for engraving.

Thanks, I'll play with the tips you gave.

Thanks guys, both of those are better than what I've been able to do so far.

Wolffie, I think that line drawing is something I can work with. I'm new at all this but learning fast.

You guys are great, Thanks again

might try inkscape
i think it has several modes that might reduce the drawing down to line art or close
woodmizer sawmill and joe's hybrid cnc, a good combination

It's fairly easy with Gimp's edge detection difference-of-gaussian and the threshold tool, but you may have to play with them to get what you want. I used the lasso tool to remove the background, the difference-of-gaussians filter (radius1=15 & radius2=2), then adjusted with the threshold tool to get this one.
