<H3>Example 5: CoverageFormat1 Table (GlyphID List)</H3>

<P>Example 5 illustrates a Coverage table that lists the GlyphIDs of all lowercase descender glyphs in a font. The table uses the list format instead of the range format because the GlyphIDs for the descender glyphs are not consecutively ordered.

<H3>Example 6: CoverageFormat2 Table (GlyphID Ranges)</H3>

<P>Example 6 shows a Coverage table that defines ten numeral glyphs (0 through 9). The table uses the range format instead of the list format because the GlyphIDs are ordered consecutively in the font. The StartCoverageIndex of zero (0) indicates that the first GlyphID, for the zero glyph, returns a Coverage Index of 0. The second GlyphID, for the numeral one (1) glyph, returns a Coverage Index of 1, and so on.

<H3>Example 7: ClassDefFormat1 Table (Class Array)</H3>

<P>The ClassDef table in Example 7 assigns class values to the lowercase glyphs in a font. The x-height glyphs are in Class 0, the ascender glyphs are in Class 1, and the descender glyphs are in Class 2. The array begins with the index for the lowercase &quot;a&quot; glyph.

<H3>Example 8: ClassDefFormat2 Table (Class Ranges)</H3>

<P>In Example 8, the ClassDef table assigns class values to four types of glyphs in the Arabic script: medium-height base glyphs, high base glyphs, very high base glyphs, and default mark glyphs. The table lists only Class 1, Class 2, and Class 3; all glyphs not explicitly assigned a class fall into Class 0. 

<P>The table uses the range format because the GlyphIDs in each class are ordered consecutively in the font. In the ClassRange array, ClassRange definitions are ordered by the Start glyph index in each range. The indices of the high base glyphs, defined in ClassRange[0], are first in the font and have a class value of 2. ClassRange[1] defines all the very high base glyphs and assigns a class value of 3. ClassRange[2] contains all default mark glyphs; the class value is 1. Class 0 consists of all the medium-height base glyphs, which are not explicitly assigned a class value.
