because each vertical column is simply one byte (lsb at the top). In this case, however, the font is only 7 bits
high so the bytes ’wrap around’.
LSB is at the top. Each byte is shown in a different colour in the diagram. When the bytes are straightened
out, it’s simple enough to find their hex values, which are shown in the diagram above each byte. Trailing
zero bytes at the end of narrow characters are not included in the file.

Now the bitmaps have to be converted to bytes. If the font is 8 bits high it becomes a fairly simple job
We’ve marked in the bits that are set for the letter "h". Remember that the bytes are "inverted", i.e. the
