'feyn' 包中 11pt 字体大小的问题

我需要绘制几个费曼图，我发现 feyn 包非常适合这个目的。我使用 MiKTeX 来编译 tex 文件。问题是，对于一些奇怪的为什么它不接受 11 pt 字体大小？我说奇怪的，因为 10pt 和 12pt 版本是完全可执行的，并且它们与 11pt 模块之间的差异仅在于一些参数的值（箭头宽度、循环半径等），这不应该导致任何编译问题......

我得到的确切错误描述是：

! I can't find file `cmr11'.

l.33 input cmr11

            ;^^I^^I^^I% ...but miss out the `generate roman'

Please type another input file name

! Emergency stop.

l.33 input cmr11

            ;^^I^^I^^I% ...but miss out the `generate roman'

下面是一个字体大小为 12pt（有效）的示例：

\documentclass [12pt]{article}
\usepackage{feyn}
\begin{document}
    $\Diagram{ fdA & & fuA \\ & g & \\ fuA && fdA }$
\end{document}

这是feyn11.mf：

% Feynman diagram font, 11pt display size, release 0.3.3, 2009 October 8.

font_identifier "FEYN"; font_size 11pt#;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% First the base size

module# := 11pt#;

% phfudge is ... what?!
phfudge# := 0pt#;       % must be, for \Diagram macro

linewidth# := 0.85pt#;      % pen width
thinlinewidth# := 0.55pt#;  % thin pen
bigarrow# := 6.5pt#;        % size of arrows
littlearrow# := 4.5pt#;
blobr# := 7pt#;         % radius of blobs and crosses

on_math_axis := 1;

% We want the roman digits from the corresponding cmr font, and that's
% all.  Therefore, we don't want to obey the `generate' command in
% cmr??.mf.  To do this, we read in cmbase, and then set generate to
% gobble its argument. 
def gobble primary g=enddef;    % gobbles its argument
input cmbase;           % Read it explicitly, rather than
                % implicitly within cmr10
let generate=gobble;
input cmr11;            % ...but miss out the `generate roman'

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% To business....

input feyn;

end

有不 cmr11.mf文件是 Computer Modern 字体标准发行版中的文件，因此在此文件上运行 Metafont 将导致错误

! I can't find file `cmr11'.

l.33 input cmr11

除非sauter也安装了该包，它可以提供 Computer Modern 字体分发中的文件的插值版本。

对于 MiKTeX，该软件包列在http://miktex.org/packages/sauter因此可以使用向导进行安装。对于 TeX Live 来说

tlmgr install sauter
