如何将 Font Awesome 转成 PNG 图标 详细教程 含源代码

最近因为项目上需要用到这个字体图标，但是它里面的许多也不能完全满足项目需要，因此就考虑将这个图标导出，然后自己再添加一些其他图标使用

搜索了些解决方案，如：http://www.oschina.net/translate/how-to-convert-font-awesome-to-png-icons，但是上面的步骤过于简单，一个新手完全不会使用，比如Python自己就一点都没接触过，因此自己走了许多弯路。

本文一方面记录以便以后自己再次使用，最重要的是将我自己的每个步骤详细的展现给有需要的大家，希望对大家有帮助。

好 还请留个好评

本文涉及所有资源可以到我的百度云下载：

font-awesome-to-png

第一步 下载图标字体源文件：

包含以下文件：

第二步 安装python-2.7.9（我电脑是64位的，截图也是64位，实际上只能安装32位，64位图标处理库（第二部会安装以处理图片）找不到安装路径，安装过程是一样的）

 第三步 安装图形处理库

安装完成后：菜单》全部程序》 Python 2.7发现已经安装成功

第四部 你下载文件里面有个 目录font-awesome-to-png 里面有将会使用的 脚本文件和字体文件（也是你第一步下载的文件）

来点其他参数

颜色变了，证明其他参数也是可靠的，大功告成。

Font Awesome to PNG
===================

This program allows you to extract the awesome
[Font Awesome] (http://fortawesome.github.com/Font-Awesome/) icons as PNG images
of specified size.

### Usage

    font-awesome-to-png.py [-h] [--color COLOR] [--filename FILENAME]
                           [--font FONT] [--css CSS] [--list] [--size SIZE]
                           icon [icon ...]

    positional arguments:
      icon                 The name(s) of the icon(s) to export (or "ALL" for
                           all icons)

    optional arguments:
      --color COLOR        Color (HTML color code or name, default: black)
      --filename FILENAME  The name of the output file (it must end with
                           ".png"). If all files are exported, it is used as a
                           prefix.
      --font FONT          Font file to use (default: fontawesome-webfont.ttf)
      --css CSS            Path to the CSS file defining icon names (instead of
                           the predefined list)
      --list               List available icon names and exit
      --size SIZE          Icon size in pixels (default: 16)

    hidden optional arguments:
     --list-update         List available icon names and codes in format suitable
                           for updating the program source.

To use the program, you need the Font Awesome TTF file, which is available in
[Font Awesome Github repository] (https://github.com/FortAwesome/Font-Awesome).

The internal icon list is matched to Font Awesome 4.1.0.  To use a later/different
version, use font-awesome.css from the Font Awesome GitHub repository.

### Examples

Export the "play" and "stop" icons as 24x24 pixels images:

    font-awesome-to-png.py --size 24 play stop

Export the asterisk icon as 32x32 pixels image, in blue:

    font-awesome-to-png.py --size 32 --color blue asterisk

Export all icons as 16x16 pixels images:

    font-awesome-to-png.py ALL
