Bit Image Graphics

Bit image graphics are created by vertically printing the bit pattern of a series
of data bytes. For example, the bit pattern of the ASCII character A (hex 41,
decimal 65) is shown in Figure 10. If this data byte is rotated 90 degrees
clockwise, the result is a vertical data byte with the most significant bit (MSB)
at the top. If each 1 (true) bit is then printed as a dot, the result is a "bit image"
plot of the ASCII character A.
