The Difference Between Bitmap and Vector Images

The Difference Between Bitmap and Vector Images

There are basically two types of graphics being used by designers - One is the bitmap which consists of pixels which are also called raster and the other is the vector graphic which consists of paths. The vector images base its operation and usability on mathematical formulas to calculate the paths and points which translate into a visible image while the bitmap image is based on grid. These grids constitute of pixel of different shade and different color.

 

What are Bitmaps or pixel graphics used for?

Bitmap images are most used for creating non-printable designs. This implies any design that you don't intend printing such as web pictures, a computer graphic, a banner or flyer that won't be printed.

 

What are Vector images used for?

Vector designs are usually used to create images which you intend printing out. This includes logos, package design, designs on t-shirts etc.

 

What are Vector graphics or images?

Vector graphics are graphic design which makes used of mathematical formulas in analyzing a series of points which forms an image, this image is composed of lines and shapes connected along a path. Vector images use geometric formulas in representing images. Vector graphics are often seen in fonts, logos, line art. A vector image has constant mathematical statements which enables it to appear smooth at any given size. It does not get blurry when stretched. Programs which can be used to create and manipulate a vector image are called draw programs. Drawing programs such as Adobe Illustrator, Macromedia Freehand, CorelDraw, CAD systems, Quark, InDesign and other page layout applications including animation software's all utilize and manipulate vector graphics. Applications such as Adobe Photoshop and CorelDraw can give out both vector and bitmap graphics. Vector images look better when displayed on monitors or high-resolution printers. Logos and types are typical examples of images that are well suited for the vector image format.

 

What are Bitmap graphics or images?

Bitmap graphics is a way of representing graphical images which are made up of pattern of dots. Bitmap images are often called raster images. Bitmap graphics are made up of grid of individual pixels having different colors. The quality of the pixel count determines the quality of the image, if the pixel count happens to be high that means that the image will be of high photographic quality, with an excellent shading and radiation. A bitmap image should not be over expanded or enlarged to avoid making the edges blurry. However, with the use of anti-aliasing, the jagged or blurry image can be corrected. Bitmaps graphics are easier to create and easy to maneuver. Bitmap graphics are best for images which require a wide range of color composition while vector images are better for images that require a few areas of solid color. You can use vector to create a nice t-shirt design, you can do that using vector so that it won't be jagged, you can still use bitmap but ensure its resolution is not less than 300.
