xmin (int)
The lesser x-coordinate of the bounding rectangle of the contents.
xmax (int)
The greater x-coordinate of the bounding rectangle of the contents.
ymin (int)
The lesser y-coordinate of the bounding rectangle of the contents.
ymax (int)
The greater y-coordinate of the bounding rectangle of the contents.
width (int)
The width of the SWF file in pixels.

Command line
与setuptools一起安装时，将放置名为swfheader的脚本 在您的bin目录中，可以使用它轻松地内省swf文件 在文件系统上：
$ swfheader some_file.swf SWF header ---------- Version: 7 Compression: False Dimensions: 1105 x 1629 Bounding box: (0, 1105, 0, 1629) Frames: 64 FPS: 1
Change history
1.2 (2012-07-18)
- Only close file handles explicitly opened by the parser itself. Fixes an issue where file handles that were passed in as parameters were prematurely closed. See https://github.com/dokai/hexagonit-swfheader/pull/1 [aleksandr-rakov]
1.1 (2010-05-08)
- Fixed a bug with parsing the “fps” and “frames” fields. The order of the fields were reversed and additionally the “fps” field was parsed incorrectly. Bug reported by Valeriy Zmiyevskoy. [dokai]
1.0.1 (2008-04-29)
- Refacted a reversed() call to make the package Python 2.3 compatible.
1.0 (2008-04-16)
- First public release [dokai]
