Detects the cells within a table zone.
public void AutoDetectCells(
Sub AutoDetectCells( _
ByVal zoneIndex As Integer _
The 0-based index of the zone inside this page IOcrPage.Zones. This zone must exist in the list and its type must be a table (OcrZone.ZoneType must be OcrZoneType.Table) otherwise, this method will throw an exception.
When this method returns, an internal array of the cells is stored in the engine containing the detected cells and their properties.
You can use table cells in one of two ways:
Perform auto-zoning on the page using IOcrPage.AutoZone, if the page contains a detected table, the a zone of type OcrZoneType.Table is created for this table. If the engine successfully detects the cells of the table, then it will fill the an internal OcrZoneCell array with the properties of the detected cells.
Manually add a new OcrZone with its type set to OcrZoneType.Table to the zones collection of a page. Leave the value of the cells to null (Nothing in VB), now use the IOcrTableZoneManager.AutoDetectCells method to instruct the engine to detect any cells in this zone and fill the array with the data.
To manipulate a cell properties other than its bound (OcrZoneCell.Bounds), get the array of detected cells through IOcrZoneCollection.GetZoneCells, change the cell background color, style or any border color, style or with. When you are done, re-set the array using IOcrZoneCollection.SetZoneCells.
It is not recommended that you manually remove or add cells to the array, the engine is very sensitive to zone boundaries and any non-accurate information will cause an error. Instead, use the various methods of IOcrTableZoneManager to manipulate the cell location and size.
For an example, refer to IOcrTableZoneManager.
