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:
| lpPrivate | Far pointer to private data area, as specified in your call to IG_status_bar_CB_register() function. |
| cyPos | Y position in the image of this raster (row). Calls for the rows are not guaranteed to be in a particular order. |
| dwHeight | 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); } } ... |

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().
