Source Sans Pro的TTF和OTF版本在Swing（Nimbus L＆F）中有不同的显示

TTF： TTF

OTF： OTF

两者都是相同的字体但不同的字体文件类型

我在Windows 7中运行Java 7

根据Adobe的Miguel Sousa的说法，错误不在字体中https://github.com/adobe/source-sans-pro/issues/32#issuecomment-23319673

我只是将默认字体设置为新字体。 TTF版本没有任何问题 

Font font_o = Font.createFont(Font.TRUETYPE_FONT, fonts.class.getResourceAsStream("fonts/TTF/SourceSansPro-Regular.ttf")); //Font font_o = Font.createFont(Font.TRUETYPE_FONT, fonts.class.getResourceAsStream("fonts/OTF/SourceSansPro-Regular.otf")); Font font_n=font_o.deriveFont(Font.PLAIN, UIManager.getLookAndFeelDefaults().getFont("defaultFont").getSize()); UIManager.getLookAndFeelDefaults().put("defaultFont",font_n);

为什么线路高度有差异？

  • 不是Java，也不是Nimbus bug，这个Font中的bug，你可以看到在Metal，Win，WinClassic和Nimbus Laf，OTF_Font上面丢失2个像素的字形
