Latex转换之PDF

近期一直在做如何使用latex将模板转换成PDF.现在写下在项目中如何实现。

1.首先你先进官网下载http://www.miktex.org/download。我用的是如下图所示。

在下载好的MikTeX找到如下目录（E:\Software）\MiKTeX 2.9\miktex\bin\x64中的miktex-xetex.

2.自己新建一个模板.tex文件和一个.bat文件。其中在.bat文件中写入miktex-2.9.4813\miktex\bin\miktex-xetex.exe -undump=xelatex test.tex（这是你自己所写的模板文件）。

下面是我自己项目中的一个模板，我的.tex文件如下

%!Tex Program = xelatex
\documentclass[a4paper]{article}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text]{Microsoft YaHei}
\begin{document}\pagestyle{empty}
\section{Unicode support}

\subsection{English}
All human beings are born free and equal in dignity and rights.

\subsection{Íslenska}
Hver maður er borinn frjáls og jafn öðrum að virðingu og réttindum.

\subsection{Русский}
Все люди рождаются свободными
и равными в своем достоинстве и
правах.

\subsection{Tiếng Việt}
Tất cả mọi người sinh ra đều được tự do và bình đẳng về nhân phẩm và
quyền lợi.

\subsection{简体中文}
你好！！！！！
\subsection{繁體中文}
每個人生來平等，享有相同的地位和權利。

\subsection{日本語}
すべての人間は自由であり、かつ、尊厳と権利とについて平等である。

\section{Legacy syntax}
When he goes---``Hello World!''\\
She replies—“Hello dear!”

\section{Ligatures}
\fontspec[Ligatures={Common, Historical}]{Times New Roman Italic}
\fontsize{12pt}{18pt}\selectfont Questo è strano assai!

\section{Numerals}
\fontspec[Numbers={OldStyle}]{Times New Roman}Old style: 1234567\\
\fontspec[Numbers={Lining}]{Times New Roman}Lining: 1234567

\end{document}

3.双击.bat文件进行运行，运行结果如下。

其中调用xetex.cmd口令程序代码如下。

 public static bool GenLatexPdf(string exeFile, string texString, string outPath, out string pdfUrl, out string error)
        {
            pdfUrl = null;
            error = null;

            if (string.IsNullOrWhiteSpace(exeFile) || !File.Exists(exeFile)) // Exe file is not exist
            {
                error = string.Format("Miktex file is not exist: {0}", exeFile);
                LogMethod.WriteLog(LogMethod.LogType.Error, error);
                return false;
            }
            if (string.IsNullOrWhiteSpace(texString)) // Tex string is empty
            {
                error = "Tex string is empty.";
                LogMethod.WriteLog(LogMethod.LogType.Error, error);
                return false;
            }
            if (string.IsNullOrWhiteSpace(outPath)) // Output path is empty
            {
                error = "Output path is empty.";
                LogMethod.WriteLog(LogMethod.LogType.Error, error);
                return false;
            }

            var now = DateTime.Now;
            outPath = string.Format(OutputPathFormat, outPath.TrimEnd('\\'), now);
            if (!Directory.Exists(outPath))
            {
                 try
                 {
                     Directory.CreateDirectory(outPath);
                 }
                 catch (IOException e) // Fail to create directory
                 {
                     error = string.Format("Fail to create directory: {0}", outPath);
                     LogMethod.WriteLog(LogMethod.LogType.Error, error);
                     return false;
                 }
            }

            string filename;
            string texPath, pdfPath;
            do
            {
                filename = Guid.NewGuid().ToString("D");
                texPath = string.Format(TexFileFormat, outPath, filename);
                pdfPath = string.Format(PdfFileFormat, outPath, filename);
            } while (File.Exists(texPath) || File.Exists(pdfPath));
            pdfUrl = string.Format(PdfUrlFormat, now, filename);

            // Write TEX

            LogMethod.WriteLog(LogMethod.LogType.Info, string.Format("Writing tex file: {0}", texPath));
            try
            {
                using (var texWriter = new StreamWriter(new FileStream(texPath, FileMode.Create, FileAccess.Write)))
                {
                    texWriter.WriteLine(texString);
                    texWriter.Flush();
                    texWriter.Close();
                }
            }
            catch (IOException e) // Fail to write tex file
            {
                error = string.Format("Fail to write tex file: {0}", texPath);
                LogMethod.WriteLog(LogMethod.LogType.Error, error);
                return false;
            }

            // Gen PDF

            try
            {
                var cmd = new Process

                                WindowStyle = ProcessWindowStyle.Hidden
                            }
                    };
                cmd.Start();
                var output = cmd.StandardOutput.ReadToEnd().Replace("\r\n", "");
                var parten = @"Output written on " + pdfPath.Replace(@"\", "/") + @" \(\d+ page\)\.";
                // Check if processing is not successfull
                if (!Regex.IsMatch(output, parten))
