## 用途说明 ##

Graphviz （Graph Visualization Software的缩写）是一个由AT&T实验室启动的开源工具包，用于绘制DOT语言脚本描述的图形。它也提供了供其它软件使用的库。Graphviz是一个自由软件，其授权为Common Public License。其Mac版本曾经获得2004年的苹果设计奖。Graphviz包括很多命令行工具，dot命令是一个用来将生成的图形转换成多种输出格式的命令行工具，其输出格式包括PostScript，PDF，SVG，PNG，含注解的文本等等。neato命令用于spring model的生成（在Mac OS版本中称为energy minimized）。twopi命令用于放射状图形的生成。circo命令用于圆形图形的生成。fdp命令另一个用于生成无向图的工具。dotty命令一个用于可视化与修改图形的图形用户界面程序。lefty命令是一个可编程的(使用一种被EZ影响的语言\[4\])控件，它可以显示DOT图形，并允许用户用鼠标在图上执行操作。Lefty可以作为MVC模型的使用图形的GUI程序中的视图部分。 DOT语言是一种文本图形描述语言。它提供了一种简单的描述图形的方法，并且可以为人类和计算机程序所理解。DOT语言文件通常是具有.gv或是.dot的文件扩展名。本文将主要介绍从源代码安装Graphviz工具以及dot命令的使用方式。

## 常用参数 ##

格式：dot -T<type> -o<outfile> <infile.dot>

输入文件是<infile.dot>，生成的格式由<type>指定，生成的文件是<outfile>。

其中-T<type>包括：

\-Tps (PostScript),

\-Tsvg -Tsvgz (Structured Vector Graphics),

\-Tfig (XFIG graphics),

\-Tmif (FrameMaker graphics),

\-Thpgl (HP pen plotters),

\-Tpcl (Laserjet printers),

\-Tpng -Tgif (bitmap graphics),

\-Tdia (GTK+ based diagrams),

\-Timap (p\_w\_picpathmap files for httpd servers for each node or edge that has a non-null "href" attribute.),

\-Tcmapx (client-side p\_w\_picpathmap for use in html and xhtml).

下面简单介绍下DOT语言的语法：

**无向图** ：在最简单的应用中，DOT语言可以用来描述一张无向图。无向图显示了对象间最简单的关系，例如人之间的友谊。使用关键字graph开始一张无向图的定义，并用大括号包含要描述的节点，双连字号（--）被用来描述节点间的关系。另外，一行的末尾需要加上分号（;）。  
graph graphname \{  
a -- b -- c;  
b -- d;  
\}

**有向图** ：类似于无向图，DOT语言也可以用来描述一张有向图，类似于流程图和树状图。其语法与无向图相似，但要在图的最开始使用关键字'digraph'，并用箭头（->）表示节点直接的关系。  
digraph graphname \{  
a -> b -> c;  
b -> d;  
\}  
**属性** ：DOT语言中，可以对节点和边添加不同的属性。这些属性可以控制节点和边的显示样式，例如颜色，形状和线形。可以在语句和句尾的分号间放置一对方括号，并在其中中放置一个或多个属性-值对。多个属性可以被逗号和空格（, ）分开。节点的属性被放置在只包含节点名称的表达式后。  
graph graphname \{  
// label属性可以改变节点的显示名称  
a \[label="Foo"\];  
// 节点形状被改变了  
b \[shape=box\];  
// a-b边和b-c边有相同的属性  
a -- b -- c \[color=blue\];  
b -- d \[style=dotted\];  
\}  
**注释** ：DOT语言支持C语言与C++风格的单行与多行注释。另外，也支持Shell脚本风格的以\#开头的注释。  
// 单行注释  
/\* 多行  
注  
释 \*/  
\# 如此的行也会被忽略。

### 示例二 操作系统的进程状态转换图 ###

下面的例子来自[http://www.graphviz.org/Gallery/undirected/process.html][http_www.graphviz.org_Gallery_undirected_process.html] 。

\[root@jfht ~\]\# cat process.gv   
graph G \{  
run -- intr;  
intr -- runbl;  
runbl -- run;  
run -- kernel;  
kernel -- zombie;  
kernel -- sleep;  
kernel -- runmem;  
sleep -- swap;  
swap -- runswap;  
runswap -- new;  
runswap -- runmem;  
new -- runmem;  
sleep -- runmem;  
\}  
  
\[root@jfht ~\]\# dot -Tpng -oprocess.png process.gv   
Format: "png" not recognized. Use one of: canon cmap cmapx cmapx\_np dot eps fig gd gd2 gif gv imap imap\_np ismap plain plain-ext ps ps2 svg svgz tk vml vmlz wbmp xdot  
\[root@jfht ~\]\# dot -Tgif -oprocess.gif process.gv

\[root@jfht ~\]\# dot -Tsvg -oprocess.svg process.gv   
\[root@jfht ~\]\#

### 示例三 中文支持 ###

要想在dot文件中使用中文，必须要安装有fontconfig-devel和freetype-devel。如示例一所示的安装中就没有这两项，

fontconfig: No (missing fontconfig-config)  
freetype: No (missing freetype-config)

先得安装上，先把Linux安装盘挂载上。安装步骤如下

\[root@jfht software\]\# find . -name "\*fontconfig\*"  
./Server/fontconfig-devel-2.4.1-7.el5.i386.rpm  
./Server/fontconfig-2.4.1-7.el5.i386.rpm  
\[root@jfht software\]\#  
\[root@jfht software\]\#  
\[root@jfht software\]\# rpm -qa | grep fontconfig  
fontconfig-2.4.1-7.el5  
\[root@jfht software\]\# rpm -ivh ./Server/fontconfig-devel-2.4.1-7.el5.i386.rpm  
warning: ./Server/fontconfig-devel-2.4.1-7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186  
error: Failed dependencies:  
freetype-devel >= 2.1.4 is needed by fontconfig-devel-2.4.1-7.el5.i386  
\[root@jfht software\]\# find . -name "freetype-devel\*rpm"  
./Server/freetype-devel-2.2.1-21.el5\_3.i386.rpm  
\[root@jfht software\]\# rpm -ivh ./Server/freetype-devel-2.2.1-21.el5\_3.i386.rpm ./Server/fontconfig-devel-2.4.1-7.el5.i386.rpm  
warning: ./Server/freetype-devel-2.2.1-21.el5\_3.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186  
Preparing... \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[100%\]  
1:freetype-devel \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[ 50%\]  
2:fontconfig-devel \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[100%\]  
\[root@jfht software\]\#

安装好这两个rpm包之后，再到graphviz源代码目录，执行

./configure --prefix=/usr

make && make install

这样dot就可以支持中文了。首先我们编写一个简单的dot文件。

\[root@jfht ~\]\# cat cn.gv  
graph G \{  
中文 -- 英文  
\}

\[root@jfht ~\]\# dot -Tgif -ocn.gif cn.gv  
Error: Invalid 2-byte UTF8 found in input. Perhaps "-Gcharset=latin1" is needed?

要注意的是：dot不支持gbk编码的中文，但可以支持UTF8的中文，所以先把它转换成UTF8编码的。

\[root@jfht ~\]\# iconv -f GBK -t UTF8 cn.gv >cn8.gv

\[root@jfht ~\]\# dot -Tgif -ocn8.gif cn8.gv  
\[root@jfht ~\]\#

### 示例四 改变中文字体 ###

默认的中文字体是宋体的，如果想改成仿宋、黑体、幼圆或别的字体，在Linux下可能没有，那么可以在Windows下找到相应的字体文件，上传的LInux上使用。步骤如下：

到C:\\Windows\\Fonts下找到simyou.ttf，用sftp上传到Linux下的/usr/share/fonts/chinese/TrueType目录。

\[root@jfht ~\]\# cd /usr/share/fonts/chinese/TrueType  
\[root@jfht TrueType\]\# **mkfontscale**   
\[root@jfht TrueType\]\# **mkfontdir**  
\[root@jfht TrueType\]\# **fc-cache**  
\[root@jfht TrueType\]\# cat fonts.dir
