如何将ditaa或点块导出为标题图形（LaTeX）？

Question

我有一个组织模式的文件，标题为ditaa和点数字。当我导出到LaTeX时，生成的图像不会放在figure环境中，而不是\caption，而不是\label。其他源代码块导出正常。

我该如何解决这个问题？

下面是一个例子组织模式文件：

* Plain source code works 

#+CAPTION: This works 
#+LABEL: fig:works 
#+BEGIN_SRC 
this is a test 
#+END_SRC 

The above (Figure [[fig:works]]) is a figure with some source code. When 
exported to LaTeX, it is placed inside a ~figure~ environment and 
given a caption and label as expected. 

* Ditaa doesn't work 

#+CAPTION: Foo 
#+LABEL: fig:foo 
#+BEGIN_SRC ditaa :file foo.png :cmdline -E 
           /-----\ 
----------------------------->| foo |<----------------------------- 
           \-----/ 
#+END_SRC 

The above (Figure [[fig:foo]]) is a ditaa figure. When exported to LaTeX, 
the image is not inside a ~figure~ environment, it is missing the 
caption, and there is no ~\label~. 

* Dot doesn't work 

#+CAPTION: Bar 
#+LABEL: fig:bar 
#+BEGIN_SRC dot :file bar.png 
digraph foo { 
    asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf -> b; 
} 
#+END_SRC 

The above (Figure [[fig:bar]]) is a dot figure. When exported to LaTeX, 
the image is not inside a ~figure~ environment, it is missing the 
caption, and there is no ~\label~.

我使用的组织模式8.2.10上的Emacs 24.3.1。

得到它的工作，你需要有#+BEGIN_SRC块和标题下#+RESULTS:节改为：

* Plain source code 

#+CAPTION: This works 
#+LABEL: fig:works 
#+BEGIN_SRC 
this is a test 
#+END_SRC 

See Figure [[fig:works]]. 

* Ditaa 

#+BEGIN_SRC ditaa :file foo.png :cmdline -E 
           /-----\ 
----------------------------->| foo |<----------------------------- 
           \-----/ 
#+END_SRC 

#+CAPTION: Foo 
#+LABEL: fig:foo 
#+RESULTS: 
[[file:foo.png]] 

See Figure [[fig:foo]]. 

* Dot 

#+BEGIN_SRC dot :file bar.png 
digraph foo { 
    asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf -> b; 
} 
#+END_SRC 

#+CAPTION: Bar 
#+LABEL: fig:bar 
#+RESULTS: 
[[file:bar.png]] 

See Figure [[fig:bar]].
