def GetTotalPages(self,fileName):
fileName
A String containing the name of the image file to query.
Number of pages in the specified file.
GetInformation and GetFormat use GetInformation internally. So, if more information about the image is required, it is recommended to call GetInformation directly and obtain the data once.
