trace bitmap on filtered JPG image
Hi Friends, I was just playing around with a JPG, a filter, and Trace Bitmap. The filter is Filters menu > Image Paint and Draw > Posterize Basic. No matter what settings I use for that filter, for example Levels = 1 or Levels = 10 (which produce very different results) after I use Trace Bitmap, the result is identical to if I use Trace Bitmap with no filter at all. What gives? Doesn't Trace Bitmap "see" the filter? I can provide screenshots or examples, if necessary.
Thanks for your help, brynn

I don't think it can. The Bitmap tracer is going to look at the actual bitmap stored in the svg data, not the generated one after filters and maybe even other svg objects sitting on top.

So do convert to bitmap on the filtered object and trace that?

Wow, fascinating!
Yes, using Bitmap Copy works!
Thank you very much :-)
