Understanding Vector And Raster Graphics
By Bharat Bista

Choosing the right design, the right designer and the right graphics is essential. Selecting the right business, the right platform and the right time is crucial. If you have an artistic hand but don't know how to write, or you have beautiful voice and you don't know how to sing, you may have a gift, but a paralyzed one.

You have a website and don't know what its composition is; you have graphics and don't know how they are designed; just the lack of this information you may lose your business.

Simple, yet complex, are the pages of your website containing graphics all together in every space. And those very graphics can hamper you, if not properly designed for an impressive deliverance to the customer.

If your site loads slowly in a browser, if your logos are not eye pleasing, if the fonts are not stylish, if the color combination and outline architecture is not smooth, you might be irritating your own costumer rather appealing to them.

Graphic design elements that are in your websites primarily are of two types; Vector and Raster.

Vector graphics is a geometric modeling of images, widely being used in Computer Graphics today. Vector graphics applies geometrical standards i.e., lines, curves, and polygons to represent images, while Raster graphics or a bit-mapped image, which is based on pixels in a grid, and contains information about the colors to be displaced in "bits". Due to this raster graphics have fixed resolution, thus cannot be resized without losing image quality.

 In addition, bitmap images have much large file sizes; however, vector graphics are prepared by many individual objects, and each of them are defined by geometrical data with individual properties allocated to it such as color, fill, and outline. Thus, vector graphics have free resolution and can bring high quality output at any scale.

 Vector images are more flexible than bitmaps, and for that reason they can be resized and stretched. Additionally, images stored as vectors enhance appearances on monitors and printers with higher resolution, while bit-mapped images always appear the same, in spite of of a device's resolution. Another advantage of vector graphics is it requires less memory than bit-mapped images do.

The word vector graphics is typically used in the context of two-dimensional computer graphics. Today almost all computer video displays transform vector representations of an image to a raster format.

Vector graphics editors usually allow a user to spin, shift, mirror, stretch, tilt, a combination of primitives into a more sophisticated objects. Vector graphics are better for designing outlines, typography, logos, technical illustrations, diagram and flowchart, while bitmap editors are more suitable for
