Raster to vector conversion is done on images which originally feature particular dimensions and lose sharpness when stretched beyond a certain point. If you have a sketch and you want a larger version of it, vector conversion is the best option available to you. In this conversion, images in bitmap formats like JPEG, GIF, PSD etc. are converted to vector formats like SVG, AI, EPS, PDF etc. When converted to a vector format, the quality of the image remains intact regardless of to what level the image is zoomed. Presently, Adobe Illustrator is the best application for such conversions.

Images converted to vector are more focused, densely colored and sharper than bitmap images. Vectorized sketches can be used for many purposes. You can get a printed version of the same and place them on a wall in your home or can use them for big posters. And if wanted, you can get them printed on your t-shirt. Isn't that amazing?

A Brief Introduction of Image Tracing

In computing jargon, image tracing is referred to the process of converting raster images to vector images. Technically a raster image is a composition of pixels. No doubt such images are useful for many purposes but they have limitations as well. On enlarging or zooming, the pixels of the images start to appear and images look unclear and fuzzy. That's the prime reason these images need to be vectorized. On the other hand, vector images are far from such issues. In these images, edges are encoded in the form of mathematical curves or lines and hence, can be zoomed to any size. You can magnify these images hundred times without worrying about the quality.

So, image tracing is basically converting a raster image into a vector image. But vectorization is successful for artificial images like cartoons, maps, clip art, logos technical drawings etc. You cannot vectorize live portraits and other such images. The reason behind this shortcoming is that artificial images are drawn with simple curves or other geometrical shapes.
