This is an extremely useful package for communative diagrams,
such as
after 10 years
A ----------------> B
The above example can be obtained by
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
...
\usepackage{amscd}
...
\[
\begin{CD}
A @>\text{after 10 years}>> B
\end{CD}
\]
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Note that the CD environment must be inside the math mode.
So \begin{align*}\begin{CD} XXX \end{CD}\end{align*} is ok,
and so is $\begin{CD} XXX \end{CD}$.

jpg for latex

標題: [隨寫] Note: jpg for latex

This note was written long time ago but I didn't post on my board.
Here it goes:
==============================
bmeps是將點陣圖如jpg png等
轉成eps或ps圖的driver
直接在黑黑的DOS視窗執行就可以
例如:
bmeps XXX.jpg XXX.ps
就可以把XXX.jpg轉出一張XXX.ps圖
接著就可以用熟悉的方法來插入圖
然後latex -> dvips -> ps2pdf
不會有問題
不過這個轉圖法會是黑白的
要轉出彩色的則多下個 -c
即
bmeps -c XXX.jpg XXX.ps
這樣的ps圖就是彩色的
只是這樣的ps圖好像會很大
爛爛的解析度就會到1MB以上
另外一個方法更好
在吳聰穎、吳聰慧的書有提
不過不是很完全
這個方法
可以用\includegraphics{XXX.jpg}
直接執行latex的話會掛掉
因為它需要bounding box
所以要用這個方法的話
得先bmeps -b XXX.jpg XXX.bb
這樣就會generate出XXX.
(其實這個bounding box也可以直接下
例如\includegraphics[bb=0 0 300 400,width=5cm,...]{XXX.jpg}
可是這個方法好像不太好)
有了bb檔之後
還要在PREAMBLE下
\DeclareGraphicsRule{.jpg}{
這樣
latex就OK
這樣子compile出來的dvi是OK的
但是直接dvips會把彩色圖弄成黑白的
這時候要再多下-I c
dvips這個driver有很多option
其指令格式是dvips [option] filename
其中[option]可以有很多
有一個網站有summarize
總之
dvips -I c filename
即可把filename.
當然啦
如果本來就沒有jpg圖檔
直接dvips filename是沒有問題的
小結：
欲放入jpg之點陣圖檔最好的方法
1) PREAMBLE放入這行指令
\DeclareGraphicsRule{.jpg}{
2) 插入圖:
\includegraphics[...]{XXX.jpg}
3) 在Command Prompt製造XXX.bb的bounding box檔:
bmeps -b XXX.jpg XXX.bb
4) 開始compile以及轉檔:
latex main
dvips -I c main
ps2pdf main.ps
要在beamer的title page放圖的指令:
\titlegraphic{...}
例如
\titlegraphic{\
放在maketitle之前都可以
這個指令會自動把圖放在正下方
如果要放左下角 可以在\includegraphics之前加個\
當然 \flushright就到右下角
如果要放兩個 一左一右
可以\flushleft \includegraphics[...]{...} \hfill \flushright
\includegraphics...
無法解決的問題:
通常把這行\titlegraphic指令插在\date之前
但是swp55總是會自動把它移到\maketitle之後
以致於圖會不見
所以目前只能在投影片確定好之好
要真正generate講稿的時候
用WinEdt 或是記事本
強制把那行指令移過去對的地方
然後再latex

boxing equations
作者: hantis (呢呢是豬) 看板: Hantis
標題: [隨寫] Note: boxing equations
時間: Tue Mar 23 12:11:12 2010
With amsmath package, there is one simple command to box a
displayed equation: \boxed. Here is an example:
\begin{equation} % equation, align, ... all work
\boxed{f = ma}
\end{equation}
The above will give a boxed equation like
__________
| |
| f = ma | (1)
|__________|
However, whenever multiple lines are involved, this does not work.
The empheq package is helpful here. This package is compatible with
many commonly used packages such as amsmath and fancybox.
Simplest usage is like
\begin{empheq}[box=\fbox]{
f & = ma \\
p & = mv
\end{empheq}
These will give something like
_______
| |
| f = ma | (1)
| p = mv | (2)
|_______|
There are other types of boxes that can be called within the help
of fancybox package. They are doublebox, ovalbox, and shadowbox.
The last one may cause problem and needs some advanced modification.
For the other two, one can just, for example,
\begin{empheq}[box=\doublebox]
....
\end{empheq}
ovalbox actually sucks. So ignore it.

\itemize in pspicture

標題: [隨寫] Note: \itemize in pspicture

Within pspicture environment, \itemize has to be wrapped within \parbox
(or some others). For example,
...
\pspicture(0,0)(8,8){
...
\rput[l](1,2){\parbox{5cm}{\
\item This is a test%

eps file output by pstricks
作者: hantis (呢呢是豬) 看板: Hantis
標題: [隨寫] Note: eps file output by latex
時間: Wed Mar 3 11:02:38 2010
pstricks and other extending packages provide
great ps figures, but the output is tricky.
The summary is:
=========================
\documentclass{article}
\usepackage{pstricks}
...
\pagestyle{empty}
...
\fcolorbox{white}{white}{
\pspicture(x1,y1)(x2,y2)
...
\endpspicture
}
=========================
(Better one figure one file.)
compile commands:
latex fig
dvips fig ----> this allows a quick preview
when done, then
dvips fig -E -o fig.eps
The file has to be (or not?) an eps file.

Word break
作者: hantis (呢呢是豬) 看板: Hantis
標題: [隨寫] Technical Notes: Word break
時間: Wed Dec 16 21:35:53 2009
To break a word after a hyphen, a "discretionary" hyphen
can be added by \-.
Example: spin-independent => spin-indepen\-dent
This "discretionary hyphen" will appear when it is necessary.
Contrarily, ABC~DEFG avoids ABC DEFG being broken into two words.
This will be especially helpful when using BibTex.
For example, the author Massimiliano Di Ventra should be
typed as Di~Ventra, Massimiliano, because Di Ventra is his
full family name.
