Clipping in Computer graphic is the process to draw pixels only to a selected region or to a well defined window. The pixels which are outside of the window are removed by the use of various defined clipping algorithms.

Clipping can be viewed as a method which determines a pixel that it is outside or inside of the window or a specified region.

In clipping in computer graphics, the primary use of the clipping is to remove the objects and lines in the clipping window.

And the Top left vertex of the polygon is clipped first in the polygon clipping.

We can clip a polygon by specifying the clipping window. Sutherland Hodgeman polygon clipping algorithm is used for the polygon clipping. In this algorithm, all the vertices of the polygon are clipped against each edge in the clipping window.

First of all, the polygon is clipped against the top left edge of the polygon window to get new vertices of the polygon and then the other.
