Important to the typographic design was the kerning, leading between lines, and typeface choice.
Panorama also offers complete support for advanced typography features, such as ligatures, swashes, small caps, ornaments, ordinals, superiors, old style, kerning, fractions, etc.
A few desktop publishing systems allow the user to change or add kerning pairs without modifying the font file itself.
In other fonts the kerning may be very different.
Whether modifying the font file with a font editor or overriding it in a particular system, the user is limited to the existing kerning features.
The kerning value for a given pair of characters is found in the table at the intersection of the classes to which they belong.
These values are based on 1000 units/em and the kerning pairs are ordered from the most negative to the most positive kerning value.
Some fonts include up to 4000 built-in kerning pairs.
