Question

LigatureLevels

Hello,

I have a question concerning LigatureLevels.

Legal values for ligatureLevel in the TextLayoutFormat are flash.text.engine.LigatureLevel.MINIMUM, flash.text.engine.LigatureLevel.COMMON, flash.text.engine.LigatureLevel.UNCOMMON, flash.text.engine.LigatureLevel.EXOTIC, flashx.textLayout.formats.FormatValue.INHERIT.

If I use flash.text.engine.LigatureLevel.NONE i get this error:

RangeError: Property ligatureLevel value none is out of range
at flashx.textLayout.property::Property$/defaultErrorHandler()
at flashx.textLayout.property::Property/setHelper()
at flashx.textLayout.formats::TextLayoutFormat/setStyleByProperty()
at flashx.textLayout.formats::TextLayoutFormat/set ligatureLevel()

What should I use if I don't want any ligatures? COMMON? But what does common mean? Which letter-combinations do get 'ligatured'?

greetings, Stefan

What the levels mean ultimately depends on the font.

In general, in Roman text, COMMON will get you ligatures like fi and fl, and MINIMUM will not. MINIMUM is for required ligatures in scripts like Arabic, where if you turn off ligatures entirely you get an unreadable mess. For most fonts in Roman text, there are no ligatures at the MINIMUM level, so that's what you should use if you want to turn ligatures off.
