What is the major disadvantages of storing information structures in display memory? A major disadvantage of storing information structures in display memory is that when color and intensity variations are incorporated into a frame buffer raster graphic device additional bit per pixel are required to produce these variations. Thus, the memory area required increase with increase in color and intensity variations. Thus larger memory areas are required to be kept reserved for color graphics display. Secondly since the frame buffer is a digital device and the CRT is and analog device so whenever some information is demanded from frame buffer, the information must first pass through a digital to analog converter and then transferred to the CRT.
WHAT IS PAINTERS ALGORITHM?
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,
