1.2.2. How vector- drawn graphics

1.2.2.1. line that id describe by the location of two end points.

1.2.2.2. Uses of Cartesian coordinates

1.2.3. Vector Drawn Images vs bitmaps

1.2.3.1. Vector Images use less memory space and have a smaller file size as compare to bitmaps

1.2.3.2. Web, Pages that use vector graphics in plug-ins download faster and when used for animation draw faster than bitmaps

1.2.3.3. vector objects easily scalable without loss of resolution or image quality

1.2.3.4. Resizing a bit mapped image requires either duplicating pixels while vector image, a rescaled image retais the quality of the original

1.2.3.5. Vector Images cant be used for photo realistic images

1.2.3.6. vector images requires plug-in for web base display

1.2.3.7. bitmaps are not so easily scalable and resizeable

1.2.3.8. bitmaps can be converted to vector using auto tracing
