Multiple Master Font Metrics
Metrics in a MM font have the MM structure – there is a set of metrics and
kerning pair values for each master font.
When you open the Metrics window in Metrics or Kerning mode for the
MM font you will see additional control that allow you to select the master
for editing:
You can also use the Metrics panel to select masters or the Axis panel to
select an intermediate master in the Preview mode.
Please note that you must set glyphs’ sidebearings and pair kerning for all
masters separately.
When you are opening or saving metrics files for a MM font, you have more
choices:
MMM format Multiple master metrics. File similar to PFM but containing
metrics and kerning information for all master fonts.
AMFM format
(save-only)
MM package of the AFM files for all masters in the font.
When you are opening or saving single-master metrics files, they will be
applied to (or generated from) the currently active master.
