Arguments:

Name	Type	Description
hMIGear	HMIGEAR	The handle of the multi-page image.
nPage	UINT	The page number from which to get the tile count.
LpTileRows	LPUINT	Pointer to a UINT variable to receive the number of tiles horizontally (number of tiles in a row).
LpTileCols	LPUINT	Pointer to a UINT variable to receive the number of tiles vertically (number of tiles in a column).

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 nTileRows; UINT nTileCols; ... / initialize multi-page image and assign it with external file / nErrCount = IG_mpf_page_count_get( hMIGear, &nPageCount ); / Count number of tiles in the first page */ if (!nErrCount && nPageCount > 0) nErrCount += IG_mpf_tile_count_get(hMIGear, 0, &nTileRows, &nTileCols ); if (!nErrCount) { printf( "Number of tiles in a row:%i\n", nTileRows ); printf( "Number of tiles in a colomns:&i\n", nTileCols ); }

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 nTileRows;
UINT nTileCols;
 ...
/* initialize multi-page image and assign it with external file */
nErrCount = IG_mpf_page_count_get( hMIGear, &nPageCount );
/* Count number of tiles in the first page */
if (!nErrCount && nPageCount > 0)
        nErrCount += IG_mpf_tile_count_get(hMIGear, 0, &nTileRows, &nTileCols );
if (!nErrCount)
{
        printf( "Number of tiles in a row:%i\n", nTileRows );
        printf( "Number of tiles in a colomns:&i\n", nTileCols );
}

Remarks:

An error is returned if the image is not associated with an external file. Pages are numbered starting with 0.
