PD4MLintroduces optional font kerning support. Kerning is an addition or reduction of space between two characters (glyphs) of a proportional font. As a rule a rendered text is visually much more pleasing when the kerning is applied.
PD4ML uses kerning pairs info from TTF/OTF fonts (if available). For the standard built-in Type1 fonts the kerning info is known and included to PD4ML product itself.
The feature is also implemented in our older development branchdue to its importance
