Hinting Alignment Zones
By default the position of the alignment zones is scaled linearly. Sometimes
this may not be satisfactory and you may need to exactly specify the
position of the alignment zones at some PPMs.
With FontLab you can adjust the position of the zones around the linearly
scaled position.
Every alignment zone has a yellow icon at the left:
You can drag this icon up or down to adjust the position of the zone at the
current PPM:
If you move the icon you will see all glyphs that have align commands
applied to that zone changed their shape.
You may find this feature useful when you have to add glyphs to an already
hinted TrueType font. New glyphs often have a different height at some
PPMs and you can correct that with the zone alignment command and
zone hinting.
