Chapter 4. Record Formats
Super Font with Metrics (SFM)
Super Font with Metrics (SFM)
The SFM record is used to provide general information about a Category
II super font and to indicate that the following CDM and/or CCD records
define characters in the super font. A super font is a double-byte font
used with certain languages to provide a large number of characters that
all have the same typeface and size.
Byte Position Bytes Field Name Description
After an SFM in the job file, any record other than a CDM, CCD, RIP,
NOP, or MSG ends the super font.
1-2 2 Record Length The length of this record, in binary, including the record length
field. For example, hex 00 16 specifies a record length of 22 bytes.
3 1 Cyclic Record Count A binary cyclic record count using modulo 256. Each record in the
job is counted, starting with hex 01 for the first record. The 255th
record is hex FF and the 256th record is hex 00. This count is used
to verify record sequence.
4 1 Control Code A binary code that identifies the record type. A value of hex 2F
identifies the SFM record.
5-8 4 X Escapement A signed binary number used to calculate the X coordinate of the
starting position for the next line. Negative values are represented
using the two's complement form. For example, hex 00 00 00 08
specifies +8 dots and hex FF FF FF F8 specifies -8 dots.
The current X line spacing value is added to the value in this field
to calculate the X position for the next line.
9-12 4 Y Escapement A signed binary number used to calculate the Y coordinate of the
starting position for the next line. Negative values are represented
using the two's complement form. For example, hex 00 00 00 1B
specifies +27 dots and hex FF FF FF E5 specifies -27 dots.
The current Y line spacing value is added to the value in this field
to calculate the Y position for the next line.
13 1 Font Rotation A binary code that identifies the font rotation.
0 (hex 00)=Upright2 (hex 02)=Inverted
1 (hex 01)=Right-Rotated3 (hex 03)=Left-Rotated
The font must be patterned in an upright rotation. This field is used
by the printing system to rotate the font to the desired rotation.
If it is to be used in more than one rotation in the same job, a super
font and all characters in the super font must be defined once for
each rotation.
14 1 Super Font Number A number, in binary, that identifies the super font. The range is 0 -
254. For example, hex 0A specifies a font number of 10.
15-22 8 Super Font Name The name of the super font in EBCDIC. The field must be left
justified and space filled to the right. For example, hex C8 C5 E6
C9 E3 E3 40 40 specifies a font name of HEWITT. This name must
match a font name in the FAR record.
