CURVE CLIPPING 2D It involve non-linear equations. The algorithm is based on he following steps:

1. If the boundary rectangle for the curved object is completely inside the window , then save the object. Boundary Rectangle Clip Window Object Save Complete Object

CURVE CLIPPING 2D

3. If the curved object is partially inside the window , then partially save the object. Clip Window Partially inside the window After Clipping

TEXT CLIPPING 2D ❑Different methods used for Character/ Text Clipping:

1. All or None String Clipping.
2. All or None Character Clipping.
3. Text Clipping

TEXT CLIPPING 2D

2. All or None Character Clipping.

In this we discard only that are not completely inside the window. Before Clipping After Clipping

TEXT CLIPPING 2D

3. Individual Character Clipping.

If an individual character overlap a clip window we clip off the parts of the character that are outside the window. Before Clipping After Clipping
