LoadFile(self, image, stream, verbose=True, index=-1)

Loads an image from a stream, putting the resulting data into image.

  • index (int) – The index of the image in the file (starting from zero).

Return type:

bool

Returns:

True if the operation succeeded, False otherwise.



SaveFile(self, image, stream, verbose=True)

Saves an image in the output stream.

Parameters:
  • image (wx.Image) – The image object which is to be affected by this operation.

  • stream (wx.OutputStream) – Opened output stream for writing the data.

  • verbose (bool) – If set to True, errors reported by the image handler will produce LogMessages.

Return type:

bool
