LEADTOOLS OCR (Leadtools.Forms.Ocr assembly)

AutoZone(OcrZoneParser,OcrZoneFillMethod,LogicalUnit,Int32,Int32,OcrProgressCallback) Method

Show in webframe







The parser used for auto zoning.

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

The fill method used in the zones found.
The units for the bounding rectangle of the new zones.
The zero-based index of the first page to decompose.
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.
Optional callback to show operation progress.
Performs auto decomposition of a range of pages in the OCR document to find the text and graphics zones using predefined parameters

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.
Remarks

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).

Example
For an example, refer to IOcrPage.AutoZone.
