MetaUML 生成的 PS 有错误

如果我使用以下示例（或任何其他示例）：

input metauml;

beginfig(1);
Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B)
endfig;

end;

它生成了我无法在 evince 和 gs 中查看的 PS：

我究竟做错了什么？

编辑：当我使用 pdflatex 时，它会生成一个正确的 pdf（至少 /usr/share/ghostscript/GS_Version/Resource/Init/Fontmap.GS 经过修改）

答案1

我也遇到了同样的问题。幸运的是，我刚刚找到了解决方案：在 ghostscript 中显示 MetaPost 输出

为了避免这个问题，正如他们建议的那样，您只需在文件开头添加以下行.mp：

prologues := 2;

然后使用或任何您喜欢的工具处理您的.mp文件。gsconvert

我对 MetaPost 了解不多，所以不知道它到底是干什么的。但它至少可以避免那个恼人的错误 :)

希望其他人也发现它有用！

答案2

创建一个 LaTeX 文档：

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics{<mpfile>.1}
\end{document}

或者使用mptopdfConTeXt 或者以这种方式使用

mpost -tex=tex <mpfile>
tex "\input epsf\relax\epsfbox{<mpfile>.1}\bye"
dvips zz

它将生成一个包含 ptmr8r 字体的 ps。用您的文件名替换。

答案3

ptmr8r 字体可能出了问题。快速谷歌搜索后，我发现了一些建议http://www.mediawiki.org/wiki/Extension:UML如何修复该问题。

答案4

如果您不想编辑文件，您可以创建自定义内存转储：

mpost -ini <<EOF

\input plain
prologues := 2
\dump

EOF

您应该会得到一个 mpout.mem 文件。将其重命名为您喜欢的任何名称（例如 foobar.mem）并将其用于：

mpost '&foobar' file

您可以定义一个别名：

alias mp2eps="mpost '&foobar'"

（您可能希望将 mem 文件放入 kpathsea 搜索路径，但我不知道如何设置它）。
