What is Vector graphics?

Rating:

Vector graphics is an image format to save images. Image formats offer advantages over traditional raster graphic formats such as Gif, Jpeg, etc. Vector graphics files are much smaller in terms of the number of bytes they contain than bitmap files of the same objects with similar details. This makes Web pages load the images faster. Another asset of vector graphics is the fact that they can be easily scaled without losing image resolution.

Vector graphics rendering is best suited to those images that have mathematically defined shapes, e.g., straight lines, simple curves, waves, circles, ellipses, squares, rectangles, and triangles, etc. In some situations, vector graphics are inferior to bitmap graphics. An example of such graphics is a photograph of a complex natural scene including trees, clouds, and other objects with fractal features. Although it is possible to render such images in vector format, it may contain several times as many bytes as the equivalent bitmap file.

These are some of the image types in vector graphics format:

• HDW (Harvard Draw)


• GEM (Ventura Publisher)
