Types of Refresh Monitors - Raster Scan and Random Scan
There are two types of refresh monitors, i.e. the Raster Scan and Random Scan that will be illustrated separately.
Note:
1) Within a Random Scan System, the Display buffer stores the picture information. Further, the device is able of producing pictures invented of lines but not of curves. Therefore, it is also termed as "Line display device or Vector display device or Calligraphic display device".
2) Within a Raster Scan System, the Frame buffer stores the picture information that is the bit plane along with m rows and n columns. Due to this type of storage the system is able of producing realistic images although the restriction is the line segments that may not show to be smooth.
Find the normalization transformation N, which uses the rectangle W(1, 1); X(5, 3); Y(4, 5) and Z(0, 3) as a window and the normalized deice screen as viewpoint.
What is bitmap and what is pixmap? The frame buffer used in the black and white system is called as bitmap which take one bit per pixel. For systems with many bits per pixel,
