LPFNIG_STATUS

This callback function is called once for each raster (row) in the image.

Declaration:

	Copy Code
typedef BOOL (ACCUAPI LPFNIG_STATUS_BAR) ( LPVOID lpPrivate, AT_PIXPOS cyPos, AT_DIMENSION dwHeight );

Arguments:

Name	Type	Description
lpPrivate	LPVOID	Far pointer to private data area, as specified in your call to IG_status_bar_CB_register() function.
cyPos	AT_PIXPOS	Y position in the image of this raster (row). Calls for the rows are not guaranteed to be in a particular order.
dwHeight	AT_DIMENSION	Total number of rasters (rows) in the image.

Return Value:

Your LPFNIG_STATUS_BAR() callback function should return TRUE if ImageGear should continue the load, save, or print operation it is performing, or FALSE if ImageGear should terminate the operation, placing an IGE_INTERRUPTED_BY_USER error on the error stack.

Supported Raster Image Formats:

This function does not process image pixels.

Sample:

Display, Image Processing, Poster, Print, FlashPix

Example:

	Copy Code
BOOL ACCUAPI StatusBar( LPVOID lpPrivate, /* Private data passed in / AT_PIXPOS cyPos, / Y position in the image / AT_DIMENSION dwHeight / Height of the image / ); ... / register the status bar callback function / err_count = IG_status_bar_CB_register(StatusBar, &si); if (err_count == 0) { fSBEnabled = TRUE; CheckMenuItem(GetMenu( hWnd),ID_OPTIONS_PROGRESSBAR,MF_CHECKED); } } else { / deregister SB function / / deregister the status bar callback function */ err_count = IG_status_bar_CB_register( NULL, NULL); if (err_count == 0) { fSBEnabled = FALSE; CheckMenuItem(GetMenu( hWnd),ID_OPTIONS_PROGRESSBAR,MF_UNCHECKED); } } ...

Copy Code

BOOL ACCUAPI StatusBar( 
   LPVOID            lpPrivate,    /* Private data passed in  */
   AT_PIXPOS            cyPos,     /* Y position in the image */
   AT_DIMENSION      dwHeight      /* Height of the image */
   );
  ...
    /* register the status bar callback function */
    err_count = IG_status_bar_CB_register(StatusBar, &si);
if (err_count == 0)
{
    fSBEnabled = TRUE;
    CheckMenuItem(GetMenu( hWnd),ID_OPTIONS_PROGRESSBAR,MF_CHECKED);
}
                        }
else
                        {
   /* deregister SB function */
   /* deregister the status bar callback function */
   err_count = IG_status_bar_CB_register( NULL, NULL);
if (err_count == 0)
{
   fSBEnabled = FALSE;
   CheckMenuItem(GetMenu( hWnd),ID_OPTIONS_PROGRESSBAR,MF_UNCHECKED);
}
                        }
  ...

Remarks:

This is the type of the callback function you specify in calling IG_status_bar_CB_register().

The calls will not necessarily be in row order. See also the description for function IG_status_bar_CB_register().
