使用fop在XSL-FO中设置字体

Question

我在.fonts/Dinarra/文件夹中有文件Dinarra LT Std-Roman.otf和Dinarra LT Std-Italic.otf。

fop.xconf中的字体配置如下：

<renderer mime="application/pdf">
  ...
  <fonts>
    ...
    <font kerning="yes" embed-url="'~/.fonts/Dinarra/DinarraLTStd-Roman.otf'" embedding-mode="subset">
      <font-triplet name="'Dinarra LT Std'" style="normal" weight="normal"/>
    </font>

    <font kerning="yes" embed-url="'~/.fonts/Dinarra/DinarraLTStd-Roman.otf'" embedding-mode="subset">
      <font-triplet name="'Dinarra LT Std'" style="normal" weight="bold"/>
    </font>

    <font kerning="yes" embed-url="'~/.fonts/Dinarra/DinarraLTStd-Italic.otf'" embedding-mode="subset">
      <font-triplet name="'Dinarra LT Std'" style="italic" weight="normal"/>
    </font>

    <font kerning="yes" embed-url="'~/.fonts/Dinarra/DinarraLTStd-Italic.otf'" embedding-mode="subset">
      <font-triplet name="'Dinarra LT Std'" style="italic" weight="bold"/>
    </font>

    <auto-detect/>
  </fonts>
</renderer>

我用fazxswpoi在fop中注册了字体。

现在我在文件fop -c ~/.fop/fop.xconf中有以下XSL-FO代码：

test.fob

使用<fo:static-content flow-name="first-page-before"> <fo:block font-family="'Dinarra LT Std'" font-size="28pt" font-style="normal" font-variant="small-caps"> <fo:block>S.E. Reverendo</fo:block> <fo:block>Gabriele Asperso</fo:block> </fo:block> </fo:static-content>编译，输出如下：

fop -c ~/.fop/fop.xconf -r test.fob test.pdf

问题是块用斜体字体呈现，而不是正常字体，而不是小字体。

如果我从字体文件夹中删除文件rev@asp-erso ~/repos/f5qg16 $ fop -c ~/.fop/fop.xconf -r test.fob test.pdf [warning] /usr/bin/fop: No java runtime was found [warning] /usr/bin/fop: No java runtime was found [warning] /usr/bin/fop: No JAVA_CMD set for run_java, falling back to JAVA_CMD = java [INFO] FopConfParser - Default page-height set to: 11.00in [INFO] FopConfParser - Default page-width set to: 8.50in [WARN] FOUserAgent - Border and padding for fo:region-before "first-page-before" should be '0' (See 6.4.14 in XSL 1.1); non-standard values are allowed if relaxed validation is enabled. (See position 23:68) [WARN] FOUserAgent - Border and padding for fo:region-after "first-page-after" should be '0' (See 6.4.14 in XSL 1.1); non-standard values are allowed if relaxed validation is enabled. (See position 25:62) [INFO] FOUserAgent - Rendered page #1. [INFO] FOUserAgent - Rendered page #2.，那么块将按预期呈现（但不是小型大写），但这样我就不能再使用斜体了。

我的问题是：

如何在XSL-FO声明中正确设置字体，以便我可以使用普通样式而不删除斜体文件？
如何设置字体以便我可以获得小型大写字母？

第2部分：一些实验

在Dinarra LT Std-Italic.otf声明之前，我已仔细检查过测试文件中的“italic”字样;

我已经三次检查文件static-content中字体文件路径的exacteness;

我删除了文件~/.fop/fop.xconf并以这种方式修改了文件~/.fop/fop-fonts.cache：

~/.fop/fop.xconf

我已经编译了重新注册字体的测试文档

<!-- ### deleted some 'font' element -->
<font kerning="yes"
      embed-url="'~/.fonts/Dinarra/DinarraLTStd-Roman.otf'"
      embedding-mode="subset">
  <font-triplet name="'Dinarra LT Std'"
                style="normal"
                weight="normal"/>
</font>

<font kerning="yes"
      embed-url="'~/.fonts/Dinarra/DinarraLTStd-Italic.otf'"
      embedding-mode="subset">
  <font-triplet name="'Dinarra LT Std'"
                style="italic"
                weight="normal"/>
</font>

<!-- ### commented-out auto-detect-->
<!-- <auto-detect/> -->

输出是：

fop -c ~/.fop/fop.xconf -r test.fob test.pdf

所以（第8行）fop找不到字体（！）。

然后我新删除了文件[warning] /usr/bin/fop: No java runtime was found [warning] /usr/bin/fop: No java runtime was found [warning] /usr/bin/fop: No JAVA_CMD set for run_java, falling back to JAVA_CMD = java [INFO] FopConfParser - Default page-height set to: 11.00in [INFO] FopConfParser - Default page-width set to: 8.50in [WARN] FOUserAgent - Border and padding for fo:region-before "first-page-before" should be '0' (See 6.4.14 in XSL 1.1); non-standard values are allowed if relaxed validation is enabled. (See position 23:68) [WARN] FOUserAgent - Border and padding for fo:region-after "first-page-after" should be '0' (See 6.4.14 in XSL 1.1); non-standard values are allowed if relaxed validation is enabled. (See position 25:62) [WARN] FOUserAgent - Font "Dinarra LT Std,normal,400" not found. Substituting with "any,normal,400". [INFO] FOUserAgent - Rendered page #1. [INFO] FOUserAgent - Rendered page #2.并重新启用了~/.fop/fop-fonts.cache指令，最后重新编译了测试文件。输出为23,175行，其中没有一个包含'Dinarra'一词，也没有'otf'这个词。

但auto-detect元素的内容仍然用斜体组成。

我不知道该怎么想。
