Line art is made up of mathematically defined curves and line segments called vectors. These vectors describe graphics according to their geometric characteristics and as a series of lines in a x,y coordinate system of the lines’ origins and endings.
For example, a slanted line can be described as a line drawn from coordinate h0 to coordinate a8 with a specific line thickness and a specific angle of inclination.
You can edit line art by moving and resizing the entire graphic or the lines and segments that compose the graphic.
Line art is resolution independent: you can scale the graphic to any size or print it on any output device at any resolution without losing quality, detail or clarity.
Line art is also known as object-oriented graphics or vector graphics.
