Curve and text clipping
The document discusses curve and text clipping techniques. It describes three methods for curve clipping: fully in, fully out, and partially in the clip window. It also outlines three approaches to text clipping: all-or-nothing string clipping, all-or-nothing character clipping, and individual character clipping where parts of characters outside the window are clipped off. The document was written by Arvind Kumar on curve and text clipping algorithms.

Presenter Arvind Kumar introduces Curve Clipping in 2D, discussing algorithms for saving, discarding, or partially saving curved objects based on their position relative to a clip window.
Arvind Kumar discusses the methods of Text Clipping in 2D, including All or None String Clipping, All or None Character Clipping, and Individual Character Clipping, detailing conditions for each method.
Curve and text clipping
- 1. CURVE & TEXTCLIPPING By: Arvind Kumar Assistant Professor Vidya College of Engineering
- 2. CURVE CLIPPING By: ArvindKumar 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
- 3. CURVE CLIPPING By: ArvindKumar 2D 2. If the boundary rectangle for the curved object is completely Outside the window , then discard the object. Clip Window Object Discard Object
- 4. CURVE CLIPPING By: ArvindKumar 2D 3. If the curved object is partially inside the window , then partially save the object. Clip Window Partially inside the window After Clipping
- 5. TEXT CLIPPING By: ArvindKumar 2D Different methods used for Character/ Text Clipping: 1. All or None String Clipping. 2. All or None Character Clipping. 3. Text Clipping
- 6. TEXT CLIPPING By: ArvindKumar 2D 1. All or None String Clipping. If all the string is inside a clip window , the it will display otherwise discard. Before Clipping After Clipping
- 7. TEXT CLIPPING By: ArvindKumar 2D 2. All or None Character Clipping. In this we discard only that are not completely inside the window. Before Clipping After Clipping
- 8. TEXT CLIPPING By: ArvindKumar 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
