<H1>IBM Font Class Parameters</H1>
<P>
This section defines the IBM Font Class and the IBM Font Subclass
parameter values to be used in the classification of font designs
by the font designer or supplier. This information is stored in
the sFamilyClass field of a font's OS/2 table.<!----><FONT FACE="Arial">sFamilyClass</FONT>
<H4><FONT COLOR=#000000>sFamilyClass</FONT></H4>
<P>
<FONT SIZE=2 COLOR=#000000>Format: 2-byte signed short</FONT>
<P>
<FONT SIZE=2 COLOR=#000000>Title: Font-family class and subclass.
Also see section 3.4.</FONT>
<P>
<FONT SIZE=2 COLOR=#000000>Description: This parameter is a classification
of font-family design. </FONT>
<P>
Comments: The font class and font subclass are registered values
assigned by IBM to each font family. This parameter is intended
for use in selecting an alternate font when the requested font
is not available. The font class is the most general and the font
subclass is the most specific. The high byte of this field contains
the family class, while the low byte contains the family subclass.
<BR>
<P>
<FONT COLOR=#000000>These values classify a font design as to
its appearance, but do not identify the specific font family,
typeface variation, designer, supplier, size, or metric table
differences. It should be noted that some font designs may be
classified equally well into more than IBM Font Class or Subclass.
Such designs should be matched to a classification for which substitution
of another font design from the same class or subclass would generally
result in a similar appearance of the presented document.</FONT><!----><FONT SIZE=2 COLOR=#000000 FACE="Arial">Class ID = 0 No Classification</FONT>
<H5><FONT SIZE=2 COLOR=#000000>Class ID = 0 No Classification</FONT>
</H5>
<P>
<FONT COLOR=#000000>This class ID is used to indicate that the
associated font has no design classification or that the design
classification is not of significance to the creator or user of
the font resource.</FONT><!----><FONT SIZE=2 COLOR=#000000 FACE="Arial">Class ID = 1 Oldstyle Serifs</FONT>
<H5><FONT SIZE=2 COLOR=#000000>Class ID = 1 Oldstyle Serifs</FONT>
</H5>
<P>
<FONT COLOR=#000000>This style is generally based upon the Latin
printing style of the 15th to 17th century, with a mild diagonal
contrast in stroke emphasis (lighter in upper left to lower right,
heavier in upper right to lower left) and bracketed serifs. This
IBM Class reflects the ISO Serif Class, Oldstyle and Legibility
Subclasses as documented in the 12/87 ISO/IEC 9541-5 draft standard.</FONT>
<H6><FONT SIZE=2 COLOR=#000000>Subclass ID = 0 : No Classification</FONT>
</H6>
<P>
<FONT COLOR=#000000>This subclass ID is used to indicate that
the associated font has no design sub-classification or that the
design subclassification is not of significance to the creator
or user of the font resource.</FONT>
<H6><FONT SIZE=2 COLOR=#000000>Subclass ID = 1 : IBM Rounded Legibility</FONT>
</H6>
<P>
<FONT COLOR=#000000>This style is generally characterized by a
large x-height, with short ascenders and descenders. Specifically,
it is distinguished by a medium resolution, hand tuned, bitmap
rendition of the more general rounded legibility subclass. An
example of this font style is the IBM Sonoran Serif family. This
IBM Subclass reflects the ISO Serif Class, Legibility Subclass,
and Rounded Specific Group as documented in the 12/87 ISO/IEC
9541-5 draft standard.</FONT>

</H6>
<P>
<FONT COLOR=#000000>This style is generally characterized by a
medium x-height, with a relatively monotone appearance and sweeping
tails based on the designs of the early Venetian printers. An

Subclass, and Modified Specific Group as documented in the 12/87
ISO/IEC 9541-5 draft standard. </FONT>
<H6><FONT SIZE=2 COLOR=#000000>Subclass ID = 5 : Dutch Modern</FONT>
</H6>
<P>
<FONT COLOR=#000000>This style is generally characterized by a
large x-height, with wedge shaped serifs and a circular appearance
to the bowls similar to the Dutch Traditional Subclass below,

IBM. </FONT>
<H6><FONT SIZE=2 COLOR=#000000>Subclass ID = 15 : Miscellaneous</FONT>
</H6>
<P>
<FONT COLOR=#000000>This subclass ID is used for miscellaneous
