Automatic Kerning Generation
The easiest way to apply kerning to a font is to use FontLab’s auto-kerning
algorithm. This algorithm analyses the shape of the glyphs in the given
pairs and automatically kerns them. You can control the pairs list that the
autokerning algorithm processes as well as other parameters.
To define kerning automatically press the
button on the toolbar, or
select the Auto Kerning command in the popup menu.
The Automatic Kerning Generation dialog box appears:
This dialog box consists of two areas: the Area of application and
Parameters.
In the first area you select the pairs for which the algorithm will compute
kerning values. You can choose between Current pair only (available if
one of the pairs is selected in the editing area), All Pairs in the current
string, or All Pairs in the following list.
The second area allows you to generate kerning for all the pairs located in a
special list file. The list files are stored in a Kerning subdirectory of
FontLab’s installation directory. You can create your own kerning pair files
or use files placed there at the time of FontLab’s installation.
