For this case I just used different polygons created with the Beizer curves tool, and joined ( Path->Union) or subtracted ( Path->Difference) from my shape until I was happy with the result. This tweaking is performed manually with some time of work. Now it comes to the painful realization that the logo is not clean at all, and it needs tweaking. Now we finally have something half useful. To do so, select all the layers and run the Path->Union process. To avoid working with so many layers, we’ll join the result into a single united layer. Once I have a set of layers that resemble the logo, I paint them all the same color (black in this case) to easily discern the shape that its taking. This creates a layer for each color (or similar), resulting in a good amount of layers.įrom the set layers I can just remove the background layers (white, whiteish) ending with a simpler version of the logo.

The first step I perform is to trace using a full color tracing. You can judge for yourself, but it seems to be some kind of jar with pickled stuff in it. Being a stamp, It is full of jitter, places with no ink, and to add injury, I just took a photo of it. Vectorising the Debian logoĪs an easy example I’ll grab the classic Debian logo and pass it through Inkscape. I’m not an expert on tracing, so I treat this tool as a black box with knobs and lights, twisting and changing until I get the best result.

The steps are common for any vectorization we might want to do. The tracing tool for Inkscape is based the Potrace, it won’t hurt you to know that this is what we’ll be using. Inkscape is an open-source vector graphics editor, and as the title implies, this is the tool that I’ll use to vectorise the logos.

There’s a lot of manuals online for this, an in-depth one with good examples can be found in Tavmjong Bah’s website. With a couple of examples, a graceful one and a crazy one.

In this post we’ll see how to create a vector file from a pixmap (jpg, png, whatever raster format that Inkscape can open). Other ones don’t even have a computer where the logo is stored. Some bars have their fancy logos already as a vector image. The idea is to do a little of propaganda: banners, t-shirts, mugs all the way!

The Trace Bitmap and Bucket Fill tools are described in parts 79-81, but I recommend starting from part 76 where I also show some manual tracing techniques.And now, for something completely different.įor a coming event we want to use logos from different bars and cafes around the block. This is a subject I cover in some detail in my tutorial series in Full Circle Magazine (free download) - though it predates the addition of centerline tracing, and the layout of the Trace Bitmap dialog has changed somewhat in 1.0. Generally the bucket tool is not a good choice - it should usually be one of the last things in your arsenal - but for filling a traced bitmap the only other practical alternative is manually drawing the shapes in a layer below the traced bitmap. Try increasing the Grow/shrink parameter, but this tool always struggles with sharp corners. Turning off the stroke and setting a fill might be all you need to do, depending on your use for the traced shape.Īs to the white border around the filled colour - that's nothing to do with the bitmap tracing process, and everything to do with the bucket fill tool.

Going back to the thin rectangle above, you can see how this would result in a shape that has two lines close together. The problem with double lines is probably that your path has a stroke but no fill. Now mentally make that rectangle thinner and thinner, until it's the thickness of a pen or pencil stroke - it still gets traced as a filled path. Consider tracing a filled rectangle - you would expect to get a filled path as a result.

Even though your image may, to you, seem to be made up of individual lines, to the tracing code they're thick shapes to be traced around. In anything other than centerline tracing mode, Bitmap tracing will produce a closed path.
