Title: White Outline Around Image Using Vector Trace Tool
Post by: markmunsterdesign on June 27, 2018, 07:04:29 AM
Good morning, I am new to Inkscape, and I'm experiencing an issue w/ the vector tracing tool that I cannot figure out. Hoping there's a solution. I have a design that I created in Procreate, exported as a JPG, and opened it in Inkscape on my desktop to vector trace it and continue the design. It's a color design, so I traced using the colors option. The trace tool picked up the design and it looks great, except for a glowing white border that goes all around the design. I tried it with as few colors as possible (7) and no smoothing, and the lite white outline is still around the entire design. I am putting the image on top of a black background, so the white outline looks messy. Any ideas on how to eliminate this? Or get a cleaner trace?

Thanks!!

(I tried using search to find topics on this, but couldn't find anything. If there are resources, please let me know. Thanks!)

Welcome to the forum!

Have you actually tested it with the black background, to make sure that the white outline is showing.  Without being able to see the image, I'm guessing that what you're seeing is anti-aliasing.  It's usually a half to 1 pixel wide, transparent area around any object.  That's how Inkscape and vector graphics create those smooth, clean, crisp lines.

Inkscape's background is transparent by default.  So even though it looks white, it's really transparent.  Inkscape offers an option to use the traditional checkerboard background, to indicate transparency, if you prefer that.  Look in Document Properties > Page tab.

But anyway, if you put it on the black background, and you still see a white strip, please share the file with us, so we can investigate.  If you can't share that file, any similar kind of file would be fine.  Just trace some other image, using the same settings, and we can still figure it out.

You can hold Ctrl, then click on the white trace result object to select it (you may want to zoom in for being able to do that more easily, if it's very thin). Then you can hit Del to delete it from the group of color traces.

It might be some antialising glitch.  Many will duplicate the object once or twice if exporting to raster to change the antialising behavior.  I find that doing Extension>Modify Path>Set Stroke Color from Path helps in many situations.  Maybe I am missing what is going on here.

Oh, and also check the stroke of your shapes, it might be that you have one applied to it that uses blur...
