发帖数: 493 | 1 The eqnarray environment has bugs in the way it calculates spacing.
Use amsmath instead:
\usepackage{amsmath}
\begin{equation}
\begin{split}
x &= \text{first line} \\
&+ \text{second line, only one equation number}
\end{split}
\end{equation}
or
\begin{multline}
x = \text{this line flushed left} \\
\text{this line flushed right, one equation number}
\end{multline}
If you have many equations and some of them are long, use
split inside gather or align instead of inside equation. |

标 题: Latex class file 问题求助
发信站: BBS 未名空间站 (Tue Apr 24 01:25:32 2007)
我自己做了一个Latex 的 class file.
其它东西都搞定了，就一个问题没有解决：
hyperref.
后来发现是\addcontentline
和hyperref的兼容问题。
如果不加这个\usepackage[pdftex,colorlinks]{hyperref}，
什么问题都没有，加上这个就是编译不过。
哪位大侠是高手，请多多指教。
我做了一个minium example, 用pdflatex编译： |

发帖数: 412 | 8 I want to insert some figures from Microsoft Visio to the document.
Somebody told me I can insert figure as following:
1) install a generic postscript printer.
2) print the figure from visio to a file using postscript printer.
3) use gsview to open the file and convert it to .eps file.
4)
\begin{figure}
% Requires \usepackage{graphicx}
\includegraphics[width=2in]{fig1.eps}\\
\caption{test}\label{fig1}
\end{figure}
However the figure does not appear in the document.
Anything wrong?
thanks. |

发帖数: 195 | 9 did you put \usepackage{graphicx}?
did you use latex or pdflatex?
in what document didn't the figure appear?
can you view the .eps with gsview? |

这个ifpdf命令到底起什么作用？
如果我的tex文档里混合eps和jpg图片
不管pdflatex还是latex都不行吧？
用pdflatex，eps图片位置呈现空白状；
用latex，根本不认jpg |
