Appendix B. Sample Font Coding<br />
Category I Font<br />
Category I Font<br />
B - 2 IJPDS Formats<br />
The following sample coding of the beginning of a category I font provides<br />
an example of how the records and fields in this font type are used. The<br />
example consists of the FDR and the first CDR.<br />
The sample coding is followed by a diagram of the bitmap described by<br />
the font file records for the first character. This allows you to see the result<br />
of field coding in the FDR and CDR.<br />
The coding is presented in groups of 8 rows of 16 bytes.<br />

This coding along with the following diagram show that the font specifies<br />
an ILS of 0 (hex 00 in position 8 in the FDR. Also, the character cell for<br />
the first character is defined by a row count of 33 (hex 00 21 in positions<br />
5-6 in the FDR), a segment count of 2 (hex 02 in position 7 of the CDR),<br />
and a final segment width of 4 (hex 04 in position 8 of the CDR).
