 |
|
刚在sir发的, 转过来和大家share一下
喝喝, 我平时一般不怎么emerge sync, 昨天sync了一下才转到modular X的
~x86的话, emerge -1u fontconfig freetype libXft, 然后打开 /etc/fonts/fonts.conf后, 找到下面这段:
| Code: |
<!--
Synthetic emboldening for fonts that do not have bold face available
-->
<match target="font">
<!-- check to see if the font is just regular -->
<test name="weight" compare="less_eq">
<int>100</int>
</test>
<!-- check to see if the pattern requests bold -->
<test target="pattern" name="weight" compare="more_eq">
<int>200</int>
</test>
<!-- set the embolden flag -->
<edit name="embolden" mode="assign">
<bool>true</bool>
</edit>
</match>
|
仔细看一下你就能看出问题: 比如运行
| Code: |
shell> fc-match -v "serif:lang=zh-cn:bold" | egrep 'embolden|weight'
|
你就会发觉, 虽然embolden是true了, 但weight还是80. 仔细想想, 让xft按weight=80 (非粗体的weight) 去渲染粗体, 出来会是什么效果呢?
所以解决办法比较简单. quick'n'dirty的话, 在</match>前加上一行
| Code: |
<edit name="weight" mode="assign"><int>200</int></edit>
|
就好了.
当然比较正规的方法是加一个单独配置到你的fontconfig.d里, 比如
| Code: |
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /hoard/fonts/fontconfig.d/65_boldify -->
<fontconfig>
<match target="font">
<test target="pattern" name="weight" compare="more_eq">
<int>200</int>
</test>
<test name="weight" compare="less"><int>200</int></test>
<edit name="weight" mode="assign"><int>200</int></edit>
<edit name="embolden"><bool>true</bool></edit>
</match>
</fontconfig>
|
如果大家早就发觉了, 不要笑我啊, 我大致翻了翻最近的帖子, 基本上都是overlay的办法 |

很好。沒有 GOT ，當年的我就放棄了使用 Gentoo。來這獲得：Gentoo 台灣中文 Ebuild 使用指南
Gentoo 台灣 是我看見，中文社區中支持一個 GNU/Linux 發行版最優秀的團體之一。 讚！！

2 eric:
印象里6.9好像没有unmask过. 当然可能因为我sync得比较少

我不是很明白你说的`好的中文支持' 是指什么, 我曾经粗略看了你的overlay指南, 爬坡问题我没遇到过, 不过除此以外, 中文支持里似乎只有粗体的问题了吧? 还请明示

主要是字体显示效果
粗斜体
使用内嵌点阵（不再发虚）
中文字体名
爬坡，是原版freetype-2.1.10引入的一个新问题
主要在qt程序里出现
打了补丁就没事了 |

| 很快就release的 freetype2.2 中文的显示质量有了很大的提高，和Fontconfig 2.4 的本土化也越来越好了。 |

emerge -u world 到最新版。
似乎我还是不能用 simsun.ttf 显示粗体………………
谁能告诉我怎么做 
MagicLinux 害人啊，我已经不会中文美化了……………… |

我试了一下，粗体是有了，但不完全，比如firefox浏览linuxsir就显示不了粗体（konqueror没问题）。字体发虚出现在终端或网页里显示代码的地方。Qt程序“爬坡”只是在用en的locale才出现，把LC_CTYPE设成zh_CN类的locale就没事了。
还有楼主的hack在我这里似乎没有影响。 |

my original post is only a demo, you shall not take it literally. you have to hand tune your fontconfig to suit your own need. |

那你能否贴一下你的font.conf给大家做个参考。
至于那个hack，我是说用了和没用，我这儿的字体效果都一样。 |

最早没贴fonts.conf, 是因为没有用单文件方式配置. 忘了从哪个版本开始fontconfig支持debian风格的 .d dir + number_leading conf piece方式. 这样虽然比较方便微调, 但是发帖的时候不容易说明白.
我现在的配置是这样的:
- 不修改系统的/etc/fonts/*
- 所有用到的字体放在 /hoard/fonts/fonts.using/ 下. (symlink即可)
- 所有配置在 /hoard/fonts/fontconfig.d/ 中(world readable), 需要使用该配置的用户建立如下 ~/.fonts.conf
| Code: |
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/fonts.conf file to configure system font access -->
<fontconfig>
<include>/hoard/fonts/fontconfig.d</include>
</fontconfig>
|
在/hoard/fonts/fontconfig.d/中有 dir, font_target, pattern_target 三个文件
dir的用途: 枚举自定义的字体目录
pattern_target的用途: fontconfig的匹配过程是双向的, 首先是应用程序向fontconfig引擎发送request, 描述自己需要的字体特徵. fontconfig在对request进行解读前, 用户可以干预应用程序的request, 这些干预由fontconfig配置文件中所有<target=pattern>的部分完成. 这些部分集中放在pattern_target文件中.
font_target的用途: fontconfig处理完所有<target=pattern>指令, 获得最终的request pattern后, 挑选出离request pattern距离最近的字体, 得到一个font description, 这包括诸如字体在哪个文件, 如何修饰 (粗体? 斜体? AA? subpixel?), 以及修饰所需的参数 (粗体-->weight多少? 斜体-->slant matrix? subpixel-->which mode?), 等等. 注意到font description和request pattern是两个不同的对象, 所以即便request pattern里要求比如粗体, 但因为simsun不支持native粗体, 所以返回的font description里, style就是normal. 所以我们需要干预fc返回的font description, 这些干预由<target=font>部分完成.
我在最早的帖子中试图说明的是, fc只负责字体匹配, 它返回的font description必须经由渲染引擎(libxft)渲染, 但是渲染引擎如何处理一个style=bold, weight=<default> (=100, 也就是没有加粗)的字体? 我觉得最可能的结果是libxft按weight=100去粗化simsun, 结果就是无用功.
这里其实还有一些tricky的地方, 因为最终调用rendering engine的是应用程序, 所以显示效果要看app怎么把从fc得到的font description传给rendering engine, 这就造成一种fontconfig配置, 对一个程序有用, 对另一个就未必. 最简单的例子是, 同样是fc+xft, rxvt-unicode可以针对每个字符挑选字体, firefox就不行. 至于Qt程序里的字体, 我猜道理也是类似的. 这也是我说为什么需要hand tune的原因, 每个人用的程序都不同.

做如下symlink:

pattern_target --> 20_pattern
font_target --> 40_font
fc将按leading number的顺序处理这些文件
