CS101 - Introduction to Computing - Q.No. 37 ( M - 3 )
Elaborate Rester Graphics with examples.
A raster graphics image, digital image, or bitmap, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computer monitor, paper, or other display device. www.vuzs.net
To illustrate the matter further - here's the letter "J":
J
Look closely at it... Take a magnifying glass to it if you like. You see a "J", the computer sees something more like this, where '.' represents a zero and 'X' represents a one:
....X
....X
....X
....X
....X
....X
....X
X...X
X...X
.XXX.
Where you see a zero, the computer instructs its video hardware to paint the current background color. A one calls for the current foreground color. Yes, it is actually a bit more complicated, but it all basically boils down to one bit or the other making a distinction
between the colors of adjacent pixels, which together form an image.

CS101 - Introduction to Computing - Q.No. 41 ( M - 10 )
write a note on each of the following:
a. Vector or Object-Oriented Graphics:
b. Bit-Mapped or Raster Graphics:
A:In Vector or object oriented graphic everything drawn is treated as object. objects retain their identity after they are drawon. these objects can later be moved, stretched, duplicated, deleted,etc. they are resolution independent and have relatively small file size. the examples are: swf, svg, wmf, ps
brass_ibrahim: Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics.
brass_ibrahim: The term "vector graphics" is mainly used today in the context of two-dimensional computer graphicsVirtually all modern 3D rendering is done using extensions of 2D vector graphics techniques .Virtually all modern 3D rendering is done using extensions of 2D vector graphics techniques
B:Bit-Mapped or Raster Graphics:
Treats everything that is drawn as a bit-map
If an object is drawn on top of another, it is difficult to move just one of them while
leaving the other untouched
Changing the resolution often requires considerable touch-up work
Relatively large file size
Examples: gif, jpg, bmp
