Cybiko Fonts File Format v1.0 by Jeff F.

---------------------------------------

 All info from Ernest S. Pazera.



Offset 0x00:  0x01 //indicates this is a font file

Offset 0x01:  charcount //number of characters in the file

Offset 0x02:  maxwidth //maximum width of the characters

Offset 0x03:  maxheight //maximum height of the characters



starting with offset 0x04, and continuing to the end of file are each of

the characters.  each of the character records look like this:



(offsets based on the beginning of the character record)

Offset 0x00: left //left coordinate of the image

Offset 0x01: top //top coordinae of the image

Offset 0x02: width //width of the image

Offset 0x03: height //height of the image



offsets 4 and above are the character bitmap information. a font is

monochrome, and the bits read from msb to lsb, so a typical letter A in 8x8

would look like:



00110000=0x30

01111000=0x78

11001100=0xCC

11001100=0xCC

11111100=0xFC

11001100=0xCC

00000000=0x00



so, the character record for this letter would look like:



... 00 00 08 08 30 78 CC CC FC CC 00 ...



from experiments, i've determined that the first character record

corresponds to character 0x20 (the space character).



i have found that 2pic.exe doesnt like too many input files, so using it to

make fonts probably won't work.  



i figure 60 character records should be about the minimum for a font (to

encompass the characters 0x20 through 0x7F and thus getting all of the

ASCII characters). i imagine that cybiko's built in fonts probably go

higher, since they have the (c) character.  i'll have to play around some

more...
