Версии TTF и OTF Source Sans Pro по-разному отображаются в Swing (Nimbus L&F)

вывод (forum.oracle.com/thread/2573652 similair, сколько его постов нет, ничего особенного)

• неправда, что ошибка Java или Nimbus, эта ошибка в шрифте, вы можете видеть, что в Metal, Win, WinClassic и Nimbus Laf в OTF_Font отсутствуют 2 пикселя над глифом

. Windows.

. Металл.

. Нимбус.

. Классический.

WinXp на Java6

. против .

• этот код поможет вам найти различия между двумя шрифтами (и сообщить обо всех различиях автору)

• возвращает все доступные атрибуты из (java.awt.font.) TextAttribute для конкретного шрифта

• вы можете получить подробные свойства из (почти) всех TextAttributes
