Translation, Rotation and Scaling - output primitives
1. Two basic approaches used in character generation are - Bitmap method and outline method.
2. All 2D geometric transformations can be obtained by using appropriate combinations of three primitive transformations (i) translation (ii) rotation (iii) scaling. Shear and reflection are two important transformations which can also be derived from primitive transformations. But looking into their vast applications, they are discussed separately and are treated as primitive transformations in many graphics packages.
The RIA should consist of: i) A simple Graphical User Interface (GUI) constructed from a simple navigation system (comprising of around 5 key frames) making use of the Flash tim

Disadvantage of the Raster Scan Display Device The major disadvantage of the raster scan is the jagged nature of the lines, happening from the information that the pixels are
What is fixed point scaling? The location of a scaled object can be controlled by a position known as the fixed point that is to remain unchanged after the scaling transformat
