Raster Display
Raster displays, typically have
an array of addressable dots
called as pixels , which can be
individually set to a particular
color or intensity, which together
forms an image.

Vector Display
Vector displays generally
display lines specified by their
endpoints.
 Vector display systems
operate by direct control of the
electron beam of a cathode ray
tube. (CRT)

They are composed of pixels.
Raster display has ability to
display areas filled with solid
colors or patterns.
They are composed of paths.
Vector display only draws lines
and characters.

In raster scan display the beam is moved
all over the screen one scan line at a time,
from top to bottom and then back to top.
In vector scan display the beam is
moved between the end points of
the graphics primitives.

Scan conversion hardware is
required.
Distorted after Zooming.
 Aliasing is the jagged appearance of
primitives as displayed on a raster
device. This phenomenon is also
known as “the jaggies”.
Scan conversion hardware is not
required.
Vector graphics can be scaled to any
size without losing quality. i.e absence
of aliasing.

Cost is low.
 Used for display purpose.
Raster graphics file formats are
JPEG, GIF and PNG.
Cost is more.
Used for Printing purpose.
Vector graphics are commonly
found today in the SVG,EPS
and PDF
