Bitmap images are made up of pixels
Pixels are tiny dots of individual color
4 x 3 pixel image = 12 pixels total

colored pixels.

The first value is always R (red), the second is G (green) and the third is B for blue.
255 is lightest shade of color
0 is the darkest shade of color
If RGB value of 0,0,0; that would mean that its red value is 0 and so too are the pixel's green
and blue values.
The color of the pixel will thus be black and of course it will have no brightness.
If we want the pixel to be 100% white, then the value of RGB will be 255,255,255
Pure red would be 255,0,0.
Pure green would be 0,255,0
Pure blue would be 0,0,255.
Pure yellow would be 255,255,0 (because in additive color space, which is what we are using,
yellow = red + green) .

when you use a scanner, the output will normally be a bitmap
More universally available interchange file formats; most bitmaps can be read by most bitmap-
based software and certain file formats such as jpeg and png can be read and written by every
paint program.

Vector graphics are created in drawing programs.
Vector drawings can usually be scaled without any loss in quality.
This makes them ideal for company logos, maps or other objects that have to be resized
frequently
Small errors in a drawing may become visible as soon as it is enlarged too much.

It is possible to rescale up a whole chunk of animation without the blockiness you would get from
doing this with bitmaps
for painting, you can specify that the bounding lines are automatically closed even when not
visible, so avoiding problems of paint flooding out
shapes easily edited
shapes can be made to animate automatically from one to another, providing they have the same
number of control points
Vector graphic can be easily converted in to easy bitmap graphic
