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.
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.

write a note on each of the following:

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 graphics Virtually 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:

If an object is drawn on top of another, it is difficult to move just one of them while
leaving the other untouched
