UINT nPageCount;
AT_ERRCOUNT nErrCount = IG_fltr_pagecount_file_format(IG_FORMAT_TIF, "picture.tif", &nPageCount);

Remarks:
If nFormat = IG_FORMAT_UNKNOWN then ImageGear attempts to detect the file format automatically, and then detects the page count. Otherwise, ImageGear skips the file format detection and counts image page using the specified format filter.
