hinting quite admirably. Be aware that although the
nomenclature in this dialog is PostScript-centric these
values are used by Fontographer for vertical alignment in
TrueType as well.
You can edit any of these values by entering new numbers
into the various fields. If you ever have occasion to go back
to how they used to be, you can press the “Recompute”
button. If that button is inactive, that means you haven’t
edited anything yet, so the recomputed values would be the
same as those which are currently showing.
Fontographer will read in all the blue values from
PostScript Type 1 fonts. It can also calculate blue values
itself, by examining characters $21-$7E (decimal 33-126) to
see where the topmost and bottommost parts of those
outlines lie. Those areas are typically what should be
included in the vertical alignment zones.
The fields in the Vertical Alignment Zones correspond
exactly to the little I-beams that appear along the left side of
the Outline Window, when the Hints layer is visible.
These I-beams are the vertical alignment zone indicators.
You select them by clicking on them with the mouse;
selected zones appear to be hollow on each end. When a
zone indicator has been selected, horizontal lines go through
it to make it easier to tell which points fall inside the zone.
You may change the size of any of the zones by dragging
either the top or bottom part of the indicators. To describe
the location of the zone numerically, you must use the
Vertical Alignment Zones dialog box.
To remove a zone, you can select it and then press the
Delete key. You may also go into the Vertical Alignment
Zones dialog box and enter “0” for both the low and high
value for a particular zone.
To create a new zone, go into the Vertical Alignment Zones
