IG_mpi_CB_reset_all

In This Topic

This function works the same way as the IG_mpi_CB_reset() function, but removes all callback data and functions from the multi-page image.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_mpi_CB_reset_all( [IN] HMIGEAR hMIGear );

Arguments:

hMIGear	HMIGEAR	The handle to the allocated multi-page image.

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:

None

Example:

	Copy Code
HMIGEAR hMIGear; /* handle to multi-page image / AT_ERRCOUNT nErrCount = IGE_SUCCESS; / will hold returned error count / DWORD dwCBID1, dwCBID2; ... nErrCount = IG_mpi_CB_set( hMIGear, (LPVOID)hMIGear, _MPWndUpdate, &dwCBID1 ); nErrCount = IG_mpi_CB_set( hMIGear, (LPVOID)hMIGear, _MPWndUpdate, &dwCBID2 ); ... nErrCount = IG_mpi_CB_reset_all( hMIGear ); ... } VOID ACCUAPI _MPWndUpdate( DWORD dwCBID, LPVOID lpPrivate, / Private data passed in */ AT_MODE nMode, UINT nPage, UINT nCount ) { switch( nMode ) { case IG_MPCBMODE_MPI_DELETE: ... break; case IG_MPCBMODE_MPI_ASSOCIATED: ... break; case IG_MPCBMODE_MPI_CLOSE: ... break; ... } }
