   AT_INT nZoneIndex,
   LPAT_RECT* lplpRects,
   LPAT_INT lpRectCount
);

Arguments:

Name Type Description
hImage HIG_REC_IMAGE Image handle.
nZoneIndex AT_INT Index of the zone in the zone list from which the information is requested.
lplpRects LPAT_RECT* Pointer to an array of AT_RECT structures for storing the requested shape information. Can't be NULL. After evaluating the result, the application should call IG_REC_free to free this array.
lpRectCount LPAT_INT Pointer to a number variable for storing the number of rectangles in the lplpRects array. Can't be NULL.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

See IG_REC_image_import.

Example:

 
Copy Code 
AT_ERRCOUNT ErrCount = 0;
HIG_REC_IMAGE higRecImage = 0;
HIGEAR higImage = 0;
AT_INT iZoneCount = 0;
LPAT_RECT lpRects = 0;
AT_INT iRectNum = 0;

ErrCount = IG_load_file("Multipage.tif", &higImage); 
ErrCount = IG_REC_image_import(higImage, &higRecImage);
ErrCount = IG_REC_zones_locate(higRecImage, NULL);

ErrCount = IG_REC_zones_count_get(higRecImage, &iZoneCount);
if(iZoneCount)
        ErrCount = IG_REC_zone_layout_get(higRecImage, 0, &lpRects, &iRectNum);

ErrCount = IG_REC_image_delete(higRecImage);
ErrCount = IG_image_delete(higImage);
ErrCount = IG_REC_free(lpRects);
