I’ve covered Rapid Resizer before but I want to go into more detail on one of its most useful features, the centerline trace. Let’s say we want to take a line drawing and sketch it with gel pens in our diecutter. If we trace it in our cutting software we will get a double line trace, and our sketch will not look natural. What we need is a way to trace down the center of the line. Rapid Resizer gives us an easy way to do this.
Find an image you want to trace. I picked this coloring book image of dolphins and downloaded it.
Next I opened the Rapid Resizer Raster to Vector Online Converter and clicked the Choose File button and navigated to the image I just downloaded. Select centerline trace from the first pulldown box and SVG from the second (you can also choose DXF if you do not have Silhouette Studio Designer Edition or another program that can open SVGs). Click the trace button.
If you chose SVG, you will see the results of the trace on the next screen. Right click to choose Save File or go to the File menu and choose Save Page As (this may vary slightly depending on your browser) and name and save the SVG to the location of your choice.
Open the SVG in your cutting software and prepare to draw as you would any other SVG sketch file.
To use these SVGs in Cricut Design Space choose vector upload.
While Rapid Resizer is the easiest way I’ve found to do centerline traces, it is limited and won’t work well on all or even most images. The best centerline tracing options are Adobe Illustrator or Corel Draw, but there are a couple of other free options. Kristy over at Craftermath has tutorials for the Autotrace web app and for Win Topo.
