我有一个BMP图像，我试图用PIL打开。但是，PIL对这张图片感到窒息......
这是一张有效的图片。图像元数据如下：

我的代码如下所示：
imageBytes = None
with open(fileName, 'rb') as f:
imageBytes = f.read()
rawImage = Image.open(StringIO.StringIO(imageBytes))
当我尝试运行htis时，我得到以下内容：
File "/home/user/__init__.py", line 149, in convert_file_adv
rawImage = Image.open(StringIO.StringIO(imageBytes))
File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 1965, in open
return factory(fp, filename)
File "/usr/lib/python2.7/dist-packages/PIL/ImageFile.py", line 91, in __init__
self._open()
File "/usr/lib/python2.7/dist-packages/PIL/BmpImagePlugin.py", line 170, in _open
self._bitmap(offset=offset)
File "/usr/lib/python2.7/dist-packages/PIL/BmpImagePlugin.py", line 102, in _bitmap
raise IOError("Unsupported BMP header type (%d)" % len(s))
IOError: Unsupported BMP header type (124)
有人可以帮助我了解我如何解决这个问题，或者解决它？
