AT_ERRCOUNT IG_mpf_page_count_get( [IN] HMIGEAR hMIGear, [OUT] LPUINT lpnPageCount );

Arguments:

Name	Type	Description
hMIGear	HMIGEAR	Handle of the allocated multi-page image.
lpnPageCount	LPUINT	Pointer indicating where to return number of pages of the associated file.

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Sample:

MFC Multipage

Example:

	Copy Code
HMIGEAR hMIGear; /* handle to multi-page image / AT_ERRCOUNT nErrCount = IGE_SUCCESS; / will hold returned error count / UINT nPageCountI = 0; / number of pages that should get from multi-page image / UINT nPageCountF = 0; / number of pages that should get from external source / HIGEAR hIGear; / handle of an image / ... / initialize multi-page image and assign it with external file */ nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCountI ); nErrCount = IG_mpf_page_count_get( hMIGear, &nPageCountF ); printf("Number of pages of multi-page image is:%i\n", nPageCountI); printf("Number of pages of external source is:%i", nPageCountF);

Copy Code

HMIGEAR  hMIGear;      /* handle to multi-page image  */
AT_ERRCOUNT             nErrCount = IGE_SUCCESS; /* will hold returned error count */
UINT nPageCountI = 0; /* number of pages that should get from multi-page image */
UINT nPageCountF = 0; /* number of pages that should get from external source */
HIGEAR hIGear;      /* handle of an image */
 ...
/* initialize multi-page image and assign it with external file */
nErrCount = IG_mpi_page_count_get( hMIGear, &nPageCountI );
nErrCount = IG_mpf_page_count_get( hMIGear, &nPageCountF );
printf("Number of pages of multi-page image is:%i\n", nPageCountI);
printf("Number of pages of external source is:%i", nPageCountF);

Remarks:

If the file is not associated with a multi-page image file, the value is 0.
