• This makes vector graphics idea for creating logos, maps, and other smooth-edged images that will be used at different sizes.
Vector Graphics can be easily modified• Unlike raster images, vector images can
be easily modified
• With a click of a button you can apply stroke and fill properties
Vector Graphics have smaller file sizes
• The mathematics of vector graphics allow large shapes to be described as extremely small amounts of data
