Only the results of these operations (the pixels) are saved in the resulting bitmap the drawing and filling operations are discarded. These programs allow users to make simple illustrations by adding text, drawing outlines, and filling outlines with a specific color. Personal computers often come with a simple paint program that produces a bitmap output file. Vectorization can be used to update images or recover work. Common vector formats are SVG, DXF, EPS, EMF and AI. Programs that do raster-to-vector conversion may accept bitmap formats such as TIFF, BMP and PNG. The input to vectorization is an image, but an image may come in many forms such as a photograph, a drawing on paper, or one of several raster file formats. Those images could have been originally made as vector images because they are based on geometric shapes or drawn with simple curves.Ĭontinuous tone photographs (such as live portraits) are not good candidates for vectorization. Synthetic images such as maps, cartoons, logos, clip art, and technical drawings are suitable for vectorization. And, just as with these other two operations, while rasterization is fairly straightforward and algorithmic, vectorization involves the reconstruction of lost information and therefore requires heuristic methods. Vectorization is the inverse operation corresponding to rasterization, as integration is to differentiation. In vectorization, the shape of the character is preserved, so artistic embellishments remain. For most applications, vectorization also does not involve optical character recognition characters are treated as lines, curves, or filled objects without attaching any significance to them. It is not examining the image and attempting to recognize or extract a three-dimensional model which may be depicted i.e. The task in vectorization is to convert a two-dimensional image into a two-dimensional vector representation of the image. Edges and filled areas are represented as mathematical curves or gradients, and they can be magnified arbitrarily (though of course the final image must also be rasterized in to be rendered, and its quality depends on the quality of the rasterization algorithm for the given inputs). Ideally, a vector image does not have the same problem. Images of sharp edges become fuzzy or jagged. The halftone dots, film grains, and pixels become apparent. If the image is magnified enough, its artifacts appear. While such an image is useful, it has some limits. In the picture, scaling the bitmap reveals the pixels while scaling the vector image preserves the shapes.Īn image does not have any structure: it is just a collection of marks on paper, grains in film, or pixels in a bitmap. The bitmap image is composed of a fixed set of pixels, while the vector image is composed of a fixed set of shapes. In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics.īackground This image illustrates the difference between bitmap and vector images.

Alternative to that is- to go old school and draw something on paper, then scan, then vectorize, and polish it.This article's lead section may be too short to adequately summarize the key points. You can get bitmap source material into your vector compositions quickly, expanding your creative options. Having them in a vector format ensures a uniform and clean appearance in all scenarios. The logo, as everyone knows, represents your company and appears on a variety of media, including your website, business cards, posters, and banners. Improve turnaround times, reduce pre-print headaches, and save money. Whether you need to get artwork ready to print, cut, or embroider, Vector Magic can help you control the flow of your images. Streamlined software and polished websites give expert-level outcomes that are simple to understand. Vector Magic accurately traces out the graphic from the source bitmap to provide an appropriate vectorization.Cedar Lake Ventures which is the company behind Vector Magic, Clipping Magic, and several data platforms, aims to give tools and information that make your professional and personal life easier. Vector Magic is a web-based as well as desktop software program that quickly and easily converts JPG and PNG images into fully functional SVGs or PDFs. What is Vector Magic and how does it work?
