I n t e r p o l a t i o n
With this operation you can move a few points and all other points of the
glyph outline between the moved points will be interpolated:
Original glyph Glyph after interpolation
As you can see, this operation can save a lot of time when you want to
proportionally modify your glyph but want to save some important values,
like stem widths.
Interpolation is extremely useful when you are making Multiple Master
fonts. Refer to the “Multiple Master Fonts” chapter for more information.
When Interpolate operation is activated a small panel appears, consisting
only of two buttons, OK and Cancel.
Press the OK button to accept any changes that you made with the
interpolation operation (you can also press the
RETURN or ENTER key on the
keyboard) or press the Cancel button to reject the changes (the
ESC key is
the equivalent of this button).
How interpolation works
1. You set the new position of several glyph points. We call these points
reference points.
