|---|---|
HMIGEAR hMIGear; /* handle to multi-page image */ AT_ERRCOUNT nErrCount = IGE_SUCCESS; /* will hold returned error count */ UINT nPageCount = 0; /* number of pages that should get from multi-page image */ UINT i, j = 0; HIGEAR hIGear; /* handle of an image */ ... /* initialize multi-page image and assign it with external file */ nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCount ); for ( i = 0; i < nPageCount; i++ ) if (!nErrCount) { nErrCount = IG_mpi_page_get( hMIGear, i, &hIGear ); if (IG_mpi_page_is_valid(hMIGear, i)) j++; } printf("Number of valid pages is:%i", j); |

Remarks:
The HIGEAR handle of any given page is not significant in this function, other than to identify the image; this function simply counts the array size.
