        [IN]  HMIGEAR hMIGear, 
        [OUT] LPAT_MODE lpFileType, 


Name Type Description

Copy Code
HMIGEAR  hMIGear;  /* handle to multi-page image */
AT_ERRCOUNT      nErrCount = IGE_SUCCESS;  /* will hold returned error count  */
AT_MODE         nFileType;
/* initialize multi-page image and assign it with external file */
        iErrCnt = IG_mpf_info_get( hMIGear, &nFileType );
        if (!iErrCnt)
        printf("File type:%i\n", (INT)nFileType);


This constant is from the format constant list, which is defined in the accucnst.h include file. If it is not associated with the file, then this function returns an error.
