Get some details back after Jpg -> Svg conversion

Postby tylerdurden83 » Wed Nov 28, 2012 10:52 pm

Hello everyone. I've used Inkscape (I'm a total newbie) to convert my business logo jpg to a svg file.
The problem was that to convert it properly without having too much noise I had to use (I think in english it's called) Luminosity Reduction.
In that way I could obtain very defined edges and everything. Then I went back to readd colors.
The problem is, that the image is now flattened, so to speak.
I'll include a comparison image.

Image

The outer frame is the Svg one where the extra details have ended flattened, while the interior one is the original one (ofc the original not being svg, it got pixelated in the zooming process).
Can you help me get back those details, or even just apply some kind of effect to mimic that original result?
Thank you so much,
Roberto

Welcome Roberto!

I'm not sure if it will be possible to retain all the details, no matter how you do it. You seem to have a pretty good trace already.

But to try and improve it, you can tweak the Trace Bitmap settings, and to some degree, retain details. (Don't miss the Options tab in Trace Bitmap dialog. Sometimes they can quite significantly improve the trace.) I recall someone using the GIMP effect called Posterize on the original raster image, in a similar situation. It will make it a solid black on white image, which is the best situation for single scan options. Then import that into Inkscape and do the trace. (The GIMP is another open source project, but is a raster editor. I'm not sure if other graphics editors might have Posterize effect as well.) In another similar situation, I saw someone blur the original image, to smooth out the pixelated areas, before tracing. It worked like magic!

Or maybe someone else will have an idea?
