issue with font features

issue with font features

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \definefontfeature[effect]%[effect=.2]
        [effect={width=.3,delta=0.4,factor=0.3}]

    \definefontfeature[oldle][onum=yes]

    \setupbodyfont[palatino]

    \starttext
    {\feature[+][effect]1234567890}
    1234567890 {\feature[+][oldle]1234567890}
    \stoptext

I wonder why the first font feature ("effect") doesn’t work. What am I
missing?

Many thanks for your help,

Pablo

because effects are not regular features so you need to create a new 
instance (which makes sense as you cannot turn a regular font into an 
italic or bold one either this way)

Many thanks for your explanation, Hans.

The new font instance is what I was missing in many of the issues I had
with features.

Many thanks for your help,

Sorry, Hans, but I don’t remember. These two months are being demanding
and my memory is far from being perfect.

I think my problems were related to glyph shapes. But in any case, if I
detect what I think it might be a bug, rest assured I’ll report it.
