About vector and bitmap graphics
Computers display graphics in either vector or bitmap format. Understanding the difference
between the two formats can help you work more efficiently. Using Flash, you can create and
animate compact vector graphics. Flash also lets you import and manipulate vector and
bitmap graphics that have been created in other applications.
Vector graphics
Vector graphics describe images using lines and curves, called vectors, that also include color
and position properties. For example, the image of a leaf is described by points through which
lines pass, creating the leaf’s outline. The color of the leaf is determined by the color of the
outline and the color of the area enclosed by the outline.
When you edit a vector graphic, you modify the properties of the lines and curves that
describe its shape. You can move, resize, reshape, and change the color of a vector graphic
without changing the quality of its appearance. Vector graphics are resolution-independent;
that is, they can be displayed on output devices of varying resolutions without losing any
quality.
