hMIGear	HMIGEAR	The handle to the allocated multi-page image.
nStartPage	UINT	The first page to delete.
nCount	UINT	The total number of pages to delete.

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; HIGEAR hIGear; / handle of an image / ... / initialize of multi-page image and assign it with external file / nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCount ); / delete all pages and shrink array to entries pages */ nErrCount = IG_mpi_page_delete( hMIGear, 0, nPageCount );

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;
HIGEAR hIGear;         /* handle of an image */
 ...
/* initialize of multi-page image and assign it with external file */
nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCount );
/* delete all pages and shrink array to entries pages */
nErrCount = IG_mpi_page_delete( hMIGear, 0, nPageCount );

Remarks:

If the deleted pages are valid images, they are deleted with the function IG_image_delete(). Pages with higher indexes are shifted by removing the number and number of pages is decreased so that all pages are numbered from 0 to nPageCount-1.

For multi-page vector documents, this function DELETES a page in the underneath vector document data. The following formats are currently supported by this API: PDF, PostScript.
