DIFFERENCE BETWEEN BITMAP IMAGES AND VECTOR GRAPHICS

DIFFERENCE BETWEEN BITMAP IMAGES AND VECTOR GRAPHICS

It’s almost impossible to discuss graphics software without first establishing an understanding of the difference between the two major 2D graphics types. Computer graphics fall into two main categoriesBitmap and Vector. You can  work with both type of graphics in Photoshop, moreover, a Photoshop file can contain both Bitmap and Vector data. Understanding the difference between the two categories helps you create, edit and import artwork.

About Bitmap Images

Bitmap images technically called Raster Images are made up of a grid of dot known as pixels. Pixels are picture element; tiny dots of individual color that make up what you see on your screen. All there tiny dots of color come together to form the image you see. the typical computer monitor has 72 or96 pixel per inch,depending on your monitor and screen setting. When working with Bitmap images, you edit pixels rather than object or shapes. Bitmap images are the  most common electronic medium for continuous-tone image such as Photographs or Digital painting,because the can represent subtle gradations of shades and color.

Bitmap images can lose detail when scaled on screen because they are resolution dependent,they contain a fixed number of pixels,and each pixel is assigned a specific location and color value.Bitmap images can look jagged if they’re printed at too low a resolution because the size of each pixel is increased.

Example: Adobe Photoshop, MS Paint

About Vector Graphics

Vector graphics are made up of mathematically defined lines and curves called vector.This means that you can move, resize, or change the color of a line without losing the quality of graphics. Vector graphics are resolution independent that is, they can be scaled to any size and printed at any resolution without losing detail or clarity . As a result, vector graphics are the best choice representing bold graphics that must retain crisp lines when scaled to various size (logos,for example).

Vector graphics have many advantages, but the primary disadvantage is that they’re unsuitable for producing photo-realistic imaginary.Vector graphics are usually made up of solid areas of color or gradients,but they cannot depict the continuous subtle tone of a photograph. That’s why most of the vector graphics you see tend to have a cartoon like appearance.

Example:Adobe Illustrator,
