Parameters

zoneParser

The parser used for auto zoning.

Note: This parameter will always contain OcrZoneParser.Default when using the LEADTOOLS OCR Advantage Engine.

fillMethod

The fill method used in the zones found.

zonesUnit

The units for the bounding rectangle of the new zones.

firstPageIndex

The zero-based index of the first page to decompose.

lastPageIndex

The zero-based index of the last page to decompose. A value of -1 means decompose up to and including the last page in the OCR document.

callback

Optional callback to show operation progress.

For more information on auto zoning and decomposition, refer to IOcrPage.AutoZone.

This method will iterate through the pages between firstPageIndex and lastPageIndex and run IOcrPage.AutoZone on each page.

You can use the OcrProgressCallback to show the operation progress or to abort it. For more information and an example, refer to OcrProgressCallback.

To perform auto decomposition to all the pages in the OCR document use AutoZone(OcrProgressCallback callback).

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
