Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
Single color line drawing algorithms involve drawing lines in a single foreground color onto a background. They are well-suited for usage with monochromatic displays. The starting point and end point of the desired line are usually given in integer coordinates, so that they lie directly on the points considered by the algorithm.
Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points.

Elements of art – group of aspects of a work of art used in teaching and analysis, in combination with the principles of art. They are texture, form, line, color, value, and shape. Perspective – the principle of creating the illusion of 3-dimensionality on a 2-dimensional source such as paper.
In a continuous-line drawing, the artist looks both at the subject and the paper, moving the medium over the paper, and creating a silhouette of the object. Like blind contour drawing, contour drawing is an artful experience that relies more on sensation than perception; it's important to be guided by instinct. [2]
A line drawing is the most direct means of expression. This type of drawing without shading or lightness, is usually the first to be attempted by an artist.It may be somewhat limited in effect, yet it conveys dimension, movement, structure and mood; it can also suggest texture to some extent.
Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering .
