This is the base class for implementing image file loading/saving, and image creation from data, all written in Python. To create a custom image handler derive a new class from wx.PyImageHandler and provide the following methods:

def DoCanRead(self, stream) --> bool
    '''Check if this handler can read the image on the stream'''

def LoadFile(self, image, stream, verbose, index) --> bool
    '''Load image data from the stream and load it into image.'''

def SaveFile(self, image, stream, verbose) --> bool
    '''Save the iamge data in image to the stream using
       this handler's image file format.'''

def GetImageCount(self, stream) --> int
    '''If this image format can hold more than one image,
       how many does the image on the stream have?'''

To activate your handler create an instance of it and pass it to wx.Image_AddHandler. Be sure to call SetName, SetType, and SetExtension from your constructor.
