def GetInformation(self,fileName,totalPages):
fileName
String containing the input file name to query.
totalPages
true to query the file for total number of pages; false, otherwise.
A CodecsImageInfo object that contains the information about the specified image.
Specifying true for totalPages can cause the process to be slow for files with large number of pages.
To quickly query the number of an image, use GetTotalPages or GetTotalPagesAsync.
To quickly query the format of an image, use GetFormat or GetFormatAsync.
