Smaller curves, e.g. counters,
generally need higher curvature
percentages than larger curves,
e.g. on the outside of a bowl.
be selected. Fit Curve also works when handles of dierent
segments are selected.
The numbers describe the percentage length of the
handle. The distance from the curve point to the intersection
of the handles equals 100 percent. 57 percent give you an
elliptic curvature.
For finer tuning, click the little triangle to expand the Fit
Curve panel into two dimensions. In that case, the first handle
on each curve segment is controlled by the x axis, while the
second one is controlled by the y axis.
Click one of the little buttons to alter the curvature of the
selected curve segments. Click the same button to adjust
other curve segments (e.g., in other letters of the same font)
accordingly. This way, you can achieve matching curvatures in
dierent curves.
3.4 LAYERS
Glyphs dierentiates between two sorts of layers: font masters
and regular layers. Font masters are needed for interpolating
instances. All glyphs in a font will always carry all font
masters set in File > Font Info > Masters (see 9, ‘Multiple Master’,
p. 73). In the Layers section of the Palette, master layers are
displayed above a separator line.
Regular layers are displayed below the separator. They
are stored on a per-glyph basis. You can have any number
of layers in a glyph. Use them for keeping variations of the
respective glyph.
