What is Bitmap Image ?
Bitmap (or raster) images are stored as a series of tiny dots called pixels.
Each pixel is actually a very small square that is assigned a color, and then
arranged in a pattern to form the image. When you zoom in on a
bitmap image you can see the individual pixels that make up that image.

33. 3333

Bitmap is derived from the words ‘bit’, which means the simplest element
in which only two digits are used, and ‘map’, which is a two-dimensional
matrix of these bits.
A bitmap is a data matrix describing the individual dots of an image that
are the smallest elements (pixels) of resolution on a computer screen or
printer.

• Using clip art galleries.

What is Vector Image ?
Vector graphics is the use of geometrical primitives such as points, lines, curves, and
shapes or polygons all of which are based on mathematical expressions to
represent images in computer graphics. Vector graphics are based on vectors (also
called paths), which lead through locations called control points or nodes.

Vector - Drawn Images v/s BitmapsVector - Drawn Images v/s Bitmaps
Vector images use less memory space and have a
smaller file size as compared to bitmaps.
For the Web, pages that use vector graphics in plug-ins
download faster, and when used for animation, draw
faster than bitmaps.
