Making a raster image bigger makes the pixels more evident-the more you zoom in, the more pronounced the squares become. You’ll be able to see pixels when you change the size of a raster. Rasters are made up of millions of pixels, which are essentially tiny blocks of colors. You undoubtedly use them on a regular basis-the images on your computer are likely to be a raster format. Raster images are typically used for photographs.
Why convert a raster to a vector? For general purposes If you’re not entirely sure which method is suitable for you, check out tracing: manual or automatic? You can then vectorize using CorelDRAW or Scan2CAD to produce a vector. You could quite easily trace over the outline by hand and scan this new drawing. If you’ve found an old technical drawing, like an electrical plan, you might find that the lines are all faded. Of course, some people work with both processes. We’ll also be showing you how you can use Scan2CAD for the conversion of technical drawings for a specialized solution. In this particular guide, we’ll be showing you how you can use CorelDRAW to convert your raster to a vector-this is an example of automatic tracing. This software detects the lines and edges of your raster image and redraws them as vector lines, polygons, curves and other entities. If you’re using a tablet, you can make use of a graphics pen to draw over the image.Īutomatic tracing, by comparison, makes use of raster-to-vector conversion software. If you’re using a laptop or computer, you can trace over the image with your mouse. Manual tracing-as the name suggests-involves tracing over the raster by hand.
You can either use manual or automatic tracing to convert your image to a vector. The process of image tracing or vectorization involves drawing over a raster image with new vector lines, shapes and text. To convert a raster to a vector, you have to vectorize the raster image-or, in other words, trace it. When you should (and shouldn’t) use CorelDRAW.Why should you automatically trace an image?.
