Arguments:
| hMIGear | The handle to the allocated multi-page image. |
| nPageCount | The new number of pages. |

Sample:
MFC Multipage
Example:
| Copy Code |
|
|---|---|
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, ... /* initialize of multi-page image and assign it with external file */ nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCount ); if (!nErrCount) { i = 0; while( !IG_mpi_page_is_valid(hMIGear, nPageCount - i - 1 ) && (i < nPageCount) ) i++; } if (!nErrCount) nErrCount = IG_mpi_page_count_set( hMIGear, nPageCount - i ); } |

Remarks:
If the size is increased, then new pages are initialized with a default value of NULL. If the array is reduced, then the removed pages are not deleted with the function IG_image_delete(). This function applies only to the image, but does not affect the associated file. The number of pages is not changed.
