导入 txfonts 积分

我试图从 txfonts 导入积分符号。在 txfonts.sty 中，我只能找到任何类型的多重积分，但找不到简单的单一积分。我肯定我遗漏了什么，有人能帮我吗？

首先，一个\limits版本...

\documentclass{article}
\usepackage{mathtools}
%%%%%%%%%%%%%%%%%%%%%%%% WHOLE txfonts PACKAGE
%\usepackage{txfonts}

%%%%%%%%%%%%%%%%%%%%%%%% JUST txfonts LARGE SYMBOLS
%%%%%%%%%%%%%%%%%%
% Math Extension %
%%%%%%%%%%%%%%%%%%

%\DeclareSymbolFont{largesymbols}{OMX}{txex}{m}{n}
%\SetSymbolFont{largesymbols}{bold}{OMX}{txex}{bx}{n}
%\DeclareFontSubstitution{OMX}{txex}{m}{n}

%%%%%%%%%%%%%%%%%%%%%%%% JUST txfont INTEGRALS
%\DeclareFontFamily{OMX}{txlargesyms}{}
\DeclareSymbolFont{txlargesyms}{OMX}{txex}{m}{n}
\DeclareMathSymbol{\txtxint}{\mathop}{txlargesyms}{82}
%\DeclareMathSymbol{\txdsint}{\mathop}{txlargesyms}{90}

\def\txint{\txtxint\limits}
%%%%%%%%%%%%%%%%%%%%%%%% 
\begin{document}
\centerline{$\int_0^x \txint_0^x$}
\[
\int_0^x\txint_0^x
\]
\end{document}

对于\nolimits版本（一行中两个字母的更改）：

\documentclass{article}
\usepackage{mathtools}
%%%%%%%%%%%%%%%%%%%%%%%% WHOLE txfonts PACKAGE
%\usepackage{txfonts}

%%%%%%%%%%%%%%%%%%%%%%%% JUST txfonts LARGE SYMBOLS
%%%%%%%%%%%%%%%%%%
% Math Extension %
%%%%%%%%%%%%%%%%%%

%\DeclareSymbolFont{largesymbols}{OMX}{txex}{m}{n}
%\SetSymbolFont{largesymbols}{bold}{OMX}{txex}{bx}{n}
%\DeclareFontSubstitution{OMX}{txex}{m}{n}

%%%%%%%%%%%%%%%%%%%%%%%% JUST txfont INTEGRALS
%\DeclareFontFamily{OMX}{txlargesyms}{}
\DeclareSymbolFont{txlargesyms}{OMX}{txex}{m}{n}
\DeclareMathSymbol{\txtxint}{\mathop}{txlargesyms}{82}
%\DeclareMathSymbol{\txdsint}{\mathop}{txlargesyms}{90}

\def\txint{\txtxint\nolimits}
%%%%%%%%%%%%%%%%%%%%%%%% 
\begin{document}
\centerline{$\int_0^x \txint_0^x$}
\[
\int_0^x\txint_0^x
\]

如果我更改\usepackage{amsmath}为\usepackage[intlimits]{amsmath}输出更改为

\limits当然，您可以使用或本地改变行为\nolimits。
