Java 源SAN Pro的TTF和OTF版本在Swing中的显示方式不同（Nimbus L&；F）

专题信托基金：

检察官办公室：

两者的字体相同，但字体文件类型不同

我正在Windows7中运行Java7

根据Adobe的米格尔·索萨（Miguel Sousa）的说法，缺陷不在字体中

我只是将默认字体设置为新字体。TTF版本的工作没有任何问题

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);

为什么线条的高度有差异？

结论（forums.oracle.com/thread/2573652与他的文章一样多，没有什么特别之处）

• 不是真的Java，也不是Nimbus bug，这个字体中的bug，你可以看到在Metal、Win、WinClassic和Nimbus Laf中，OTF_字体缺少符号上方的2个像素

。窗户

。金属

。灵气

。经典

Java6上的WinXp

。对

• 此代码将帮助您找到两种字体之间的差异（并向作者报告所有差异）

• 从具体字体的（java.awt.font.）texttribute返回所有可用的属性

• 您可以从（几乎）所有TextAttributes获取详细属性

有输出

java.awt.font.TextAttribute(family)
java.awt.font.TextAttribute(weight)
java.awt.font.TextAttribute(width)
java.awt.font.TextAttribute(posture)
java.awt.font.TextAttribute(size)
java.awt.font.TextAttribute(transform)
java.awt.font.TextAttribute(superscript)
java.awt.font.TextAttribute(char_replacement)
java.awt.font.TextAttribute(foreground)
java.awt.font.TextAttribute(background)
java.awt.font.TextAttribute(underline)
java.awt.font.TextAttribute(strikethrough)
java.awt.font.TextAttribute(run_direction)
java.awt.font.TextAttribute(bidi_embedding)
java.awt.font.TextAttribute(justification)
java.awt.font.TextAttribute(input method highlight)
java.awt.font.TextAttribute(input method underline)
java.awt.font.TextAttribute(swap_colors)
java.awt.font.TextAttribute(numeric_shaping)

这如何帮助我比较Adobe Source Sans Pro的otf和ttf版本？此外，它不会将属性值打印到控制台，但只打印存在哪些属性，您是否查看了Github问题？

1）这如何帮助我比较Adobe Source Sans Pro的otf和ttf版本？

-->每种字体都有许多属性，其中一个是插入、空边框，显示Unicodes glyph中较高值的可用空间

2）它也不会将属性的值打印到控制台，而是只打印存在哪些属性

-->同样，您可以从所有属性中获取详细属性3）Darryl Burke的Visual Font Designer的原因，不要在我的回答中重新发明轮子

4）你看了Github的问题了吗？

-->开源的标准答案……不，你误解了什么。我正在使用Adobe提供的字体源Sans Pro。我使用的是这种字体的otf或ttf版本。只有otf字体有一些问题（行高？），但是Adobe的Miguel说它们都是一样的。你可以从列表中选择字体的一个版本（ttf或otf？），但你不能比较它们，也不能在otf和ttf版本之间选择直接比较。你已经知道我提交了一个不存在的问题-这很奇怪-它应该存在，因为我有一个bug id=（对于Oracle和Java来说，这是非常令人失望的，对于解决所有问题的这个问题/答案没有答案。所有这些都让我们一无所获，Adobe说这不是字体错误，Oracle什么也没有说，所以对我来说这是Java错误。不，你误解了一些东西。请确保没有，我在这里删除我的答案，以避免进一步讨论关于About，我到底误解了什么？我在这里尝试了ttf版本：看起来很棒，然后尝试了otf版本（评论ttf版本）lokks不一样，看到上面的两张图片，看到“O”上面的空白我看到了，但我试图避免对我这边的方法进行任何调试，没有别的：-）在FontForge中，两个版本（otf，ttf）实际上是一样的，看起来也一样，似乎是一个Java Swing（Nimbus L&F）错误如果它也被其他Java用户复制，那将是一个错误，所以让我们看看社区怎么说，也许我们必须为此提交一份错误报告。我将不断更新此stackoverflow问题，以便将来其他用户知道
