Vector images are defined mathematically as a series of points joined by lines.
Each object is self-contained, with properties such as color, shape, outline, size, and
position on the screen.

Since each object is self-contained, you can move and change its properties
over and over again while maintaining its original clarity and crispness.

Vector-based drawings are resolution independent. This means that they appear
at the maximum resolution of the output device, such as your printer or monitor. The
image quality of your drawing is better if you print from a 600 dots per inch (dpi) printer
than from a 300 dpi printer.

Remember  that objects are created as collections of lines in vector graphics,
and bitmap images are made of individual pixels arranged in patterns. Of the two
formats, bitmap images are great for photographs because they tend to offer greater
subtleties for shading and texture but require more memory and take longer to print.
Vector images are best for drawings that need sharper lines, more detail, and easy
modification. Vector images require far less printing resources.
