Compuetrs can many, many kinds of graphics from simple line drawings to three-dimensional
animations. But all graphics files fall into one of two basic categories, known as
bitmapped and vector files.
A grid, called a bitmap, whose cells are filled with one or more colors. The
individual cells in the grid can all be filled with the same color or each cell can
contain a different color. The term raster is sometimes used to describe bitmap
images. Bitmap images also may be reffered to as bitmapped images. The easiest way
to imagine how bitmaps work is to think of your computer's monitor. It displays images
as collections of individual colored pixels. Each pixel is a cell in the grid of a
bitmapped image. In fact, the individual pieces that make up a bitmapped image are
often called pixels.
thickness, position, color, and fill of lines or closed graphical shapes.
Some types of graphics programs work with bitmaps; some work with vectors; and some
can work with both. Each type of graphics file has its own advantages and disadvantages
Vector-based software is your best choice if you want the flexibility of resizing an
image without degrading its sharpness, the ability to reposition elements easily in
an image, or the ability to acheive an illustrative look as when drawing with apen or
pencil.

VECTOR
A set of Vectors, which are mathematical equations describing the size, shape,thickness, position, color, and fill of lines or closed graphical shapes.
