在哪里可以找到所描述的风格集/变体？

如果我使用带有 的字体LuaTeX，通常，我知道有TeXGyrePagellaX多少个（ ）并且我知道如何激活它们（），但是：它们之间的实际区别是什么，在哪里可以找到描述？我花了很多很多时间在我的字体文件和互联网上寻找它，最后我找到了 变体的描述，但没有。我想有一个简单的解决方案......StylisticSetotfinfo -f TeXGyrePagellaX-Regular.otf\setmainfont{TeX Gyre Pagella X}[variant=2]Linux LibertinePagella X

答案1

FontForge可以用来检查不同风格变体的替换：

Element -> Font Info -> Lookups -> GSUB -> ss01, ss02, ss03, ss04

简而言之：

  • ss01：似乎是 和 的ss02并ss03集ss04。
  • ss02: at，copyright，fraction，paragraph，registered被其替代词替换，例如上标位置的版权。
  • ss03：一些希腊字母的替代品。
  • ss04：长音符的替代品以及带有长音符的字母，替代形式更短。

没有 FontForge

TeXGyrePagellaX-Regular.otf似乎源自texgyrepagella-regular.pdf。其文档可在以下位置找到：

TDS:doc/fonts/tex-gyre/

答案2

我从以下网址下载了 Adob​​e 字体开发工具包http://www.adobe.com/devnet/opentype/afdko.html并安装它。

然后我就跑了

spot -F /usr/local/texlive/2016/texmf-dist/fonts/opentype/public/newpx/TeXGyrePagellaX-Regular.otf

获取功能列表：

GSUB Features:

    Default language system
        [ 0]='aalt' LookupListIndex: 0 1 
        [ 1]='c2sc' LookupListIndex: 14 
        [ 2]='dlig' LookupListIndex: 13 
        [ 3]='frac' LookupListIndex: 4 
        [ 4]='hlig' LookupListIndex: 12 
        [ 5]='liga' LookupListIndex: 10 11 
        [ 6]='lnum' LookupListIndex: 6 
        [ 7]='onum' LookupListIndex: 5 
        [ 8]='pnum' LookupListIndex: 7 
        [ 9]='salt' LookupListIndex: 15 
        [10]='smcp' LookupListIndex: 3 
        [11]='ss01' LookupListIndex: 16 
        [12]='ss02' LookupListIndex: 17 
        [13]='ss03' LookupListIndex: 18 
        [14]='ss04' LookupListIndex: 19 
        [15]='sups' LookupListIndex: 9 
        [16]='tnum' LookupListIndex: 8 
        [17]='zero' LookupListIndex: 20

下一步是查看 GSUB 表

spot -t GSUB /usr/local/texlive/2016/texmf-dist/fonts/opentype/public/newpx/TeXGyrePagellaX-Regular.otf > gsub.txt

我得到的文件很长，但也信息量很大。搜索Lookup [16]显示
