Interpolate script

jbl

Hello all,
Not sure if this is Robofab or Robofont related:
When I try to run this script (grabbed from robofab.com) :

# robothon 2009
# interpolate two glyphs in the same font a bunch of times
from robofab.world import CurrentFont
f = CurrentFont()
for i in range(0, 10):
    factor = i * .1
    name = "result_%f" % factor
    print "interpolating", name
    f[name].interpolate(factor, f["A"], f["B"])
f.update()

I get this error:

interpolating result_0.000000
Traceback (most recent call last):
  File "", line 9, in 
  File "lib/fontObjects/robofabWrapper.pyc", line 3173, in __getitem__
  File "lib/fontObjects/robofabWrapper.pyc", line 3180, in getGlyph
RoboFontError: Glyph result_0.000000 not in font.</code>

Any idea why? Since it says "Robofont Error"… I might as well ask here :)

thank you!

you are asking the font for a glyph that doesn't exist

# robothon 2009
# interpolate two glyphs in the same font a bunch of times
from robofab.world import CurrentFont
f = CurrentFont()
for i in range(0, 10):
    factor = i * .1
    name = "result_%f" % factor
    print "interpolating", name

    # create a new glyph
    f.newGlyph(name, clear=True)

    f[name].interpolate(factor, f["A"], f["B"])
f.update()

good luck
