Manual Vectorization vs Automated Vector Tracing
To vectorize a raster (bitmap) image into vector format you can either do it by manually drawing node by node using vector drawing software or you can use automated tracing tools within the vector editors. In Adobe Illustrator - which is what I use - the auto-trace tool is called "Live Trace". Auto tracing is great and almost instant, just a couple of clicks and you are done, so you can save tons of time and money, but automated tracing doesn't work well with all images. It really depends on the original bitmap graphic; the quality, the contrast between colors, even the size. I think the perfect candidates for automated vectorization or auto-tracing are images that are: Non-geometrical "free flowing" shapes - like the sample tree below Large, good quality originals that are black and white or high contrast colors with very clear distinction between each color. Photographs that do not need to be changed to simple line drawings The imag...
