Bit mapped Graphic and Vector Graphic
Advantages and disadvantageous of bit mapped graphic representation
Disadvatages
advantages
Bitmap files may be easily created from existing pixel data stored in an array in memory.
Retrieving pixel data stored in a bitmap file may often be accomplished by using a set of coordinates that allows the data to be conceptualised as a grid.
shrinking images are hard to do you have to change the shape all to gather
Vector Graphic
advantages
disadvantages
Vector files are small because they contain a lot less data than raster image files. *
Vector graphics are more flexible than raster graphics because they can be easily scaled up and down without any loss to the quality of the image.

hey aren’t too suitable for encoding videos or pictures from the real world. They do support mixed compositions, though.
The data used for describing them needs to be processed by powerful machines. If the volume of data is high, it slows down image rendering even if the files are small in size.
One more disadvantage is that even the smallest of errors in the drawings are visible when you enlarge images to an extent. These incidents can affect image quality, especially when used in animation.
how vector graphics are represented
Vector graphics is the use of polygons to represent images in computer graphics. Vector graphics are based on vectors, which lead through locations called control points or nodes. ... Vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality.
