Turn Line Drawing Images into Vector Files
Rapid Resizer's tracer automatically turns images into vector files in formats including PDF, SVG, and DXF. The resulting file won't become pixellated when you increase its size.
This is helpful for designing logos for example, so your design remains sharp when it's printed in different sizes.
Below you can see the pixels and blur of the original image. When it has gone through the vectorizer, the image has sharp clear lines.
This is also handy if you need to get a raster file into a cutting machine that requires a DXF or other vector format.
