A SubStation Style.
|
|
|
|
In SubStation, each subtitle (:class:`SSAEvent`) is associated with a style which defines its font, color, etc.
|
|
Like a subtitle event, a style also consists of "fields"; see :attr:`SSAStyle.FIELDS` for a list
|
|
(note the spelling, which is different from SubStation proper).
|
|
|
|
Subtitles and styles are connected via an :class:`SSAFile` they belong to. :attr:`SSAEvent.style` is a string
|
|
which is (or should be) a key in the :attr:`SSAFile.styles` dict. Note that style name is stored separately;
|
|
a given :class:`SSAStyle` instance has no particular name itself.
|
|
|
|
This class defines equality (equality of all fields).
