Parameters

fileName

String containing the input file name to query.

totalPages

true to query the file for total number of pages; false, otherwise.

pageNumber

Page number in the file to query.

Return Value

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.
