Я не знаю ни одного C # API или библиотеки, которая могла бы достичь этого.Однако, если у вас достаточно знаний C / C ++ для создания оболочки для C #, я вижу два варианта:
Пространство имен System.Windows.Media очень ограничено.Возможно, за этим стоит мощный движок (WCS?), Но доступна только небольшая часть.
Обновление:
Вот код C #, который можно выполнить с помощью преобразованияWCS.Конечно, он может использовать оболочку, которая облегчит использование:
