Figure 18: Bitmap Encoding
As you can see the letter
h
will take up ?ve bytes with the last ?ve bits being zero padded
to form a full
byte. So if you continue the process you will get the character data as seen in
table 5.1.2.

The second part of the font ?le is the character table. The cha
racter table is comprised of three bytes for
every glyph in the font ?le.
The ?rst two bytes represents the position, in bytes, of the g
lyph stored MSB LSB referenced from the
beginning of the ?le (including the header. The third byte is
the width of the glyph in pixels. So because
there will be 0x09 bytes in the character table (three bytes for each glyph) and four bytes in the header
section, the ?rst entry in the table will be 13, or 0x00 0x0D in
hexadecimal, and 0x05 for the width.
To calculate the second entry in the character table, representing the position and width of the second
glyph, take the offset of the ?rst entry and add the size of the
?rst bitmap in bytes. Since the ?rst glyph
occupies 0x05 bytes as seen in table 5.1.2 above, and the offset is 0x00 0x0D, the offset of the second entry
will be 0x00 0x12 and the width of the glyph is 0x03.
Calculate the third entry the same way as the second to get
table 10
below.

Once completed, place the character table after the header and the character data aat the end, as seen in
table 11.
