在查看wxpython自带的demo的源代码的时候总是有一点特别奇怪，它那里有一个文件是images.py,它里有一句是对一个解释是这样的：
This file was generated by C:\PROJECTS\wx\wxPython\demo\encode_bitmaps.py
打开这个encode_bitmaps.py文件一看，发现居然是对wxpython.tools里一个叫img2py的例程的调用。
原来这个img2py是将图像转为以py文件存储的程序哦。终于明白了。
于是退出python的环境，到命令行下运行img2py看看。
果然有一大堆的参数。
下面是帮助的东东哦。
[myphp]
img2py.py -- Convert an image to PNG format and embed it in a Python
module with appropriate code so it can be loaded into
a program at runtime. The benefit is that since it is
Python source code it can be delivered as a .pyc or
'compiled' into the program using freeze, py2exe, etc.
Usage:
img2py.py [options] image_file python_file
Options:
-m <#rrggbb> If the original image has a mask or transparency defined
it will be used by default. You can use this option to
override the default or provide a new mask by specifying
a colour in the image to mark as transparent.
-n <name> Normally generic names (getBitmap, etc.) are used for the
image access functions. If you use this option you can
specify a name that should be used to customize the access
fucntions, (getNameBitmap, etc.)
-c Maintain a catalog of names that can be used to reference
images. Catalog can be accessed via catalog and index attributes
of the module. If the -n <name> option is specified then <name>
is used for the catalog key and index value, otherwise
the filename without any path or extension is used as the key.
-a This flag specifies that the python_file should be appended
to instead of overwritten. This in combination with -n will
allow you to put multiple images in one Python source file.
-u Don't use compression. Leaves the data uncompressed.
-i Also output a function to return the image as a wxIcon.
[/myphp]
呵呵，明白了。
