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 3. If we rotate this data byte 90 degrees
clockwise, we have a vertical data byte with the most significant bit (MSB) at
the top. If we then print each 1 (true) bit as a dot, the result is a "bit image" plot
of the ASCII character A.
