Members

Value	Member	Description
0	LoadImage	Image load operation. Used when pages are added to an OCR document through one of IOcrPageCollection.AddPage, IOcrPageCollection.AddPages, IOcrPageCollection.InsertPage or IOcrPageCollection.InsertPages methods.
1	SaveImage	Image save operation. Used when IOcrPage.Recognize is called.
2	ProcessImage	Image preprocessing operation. Used when IOcrPage.AutoPreprocess is called.
3	FindZones	Page-layout decomposition operation. Used when IOcrPage.AutoZone is called.
4	RecognizeFirstPass	First pass recognition operation that may be used when IOcrPage.Recognize is used with the MOR recognition module
5	RecognizeSecondPass	Second pass recognition operation. Used when IOcrPage.Recognize is called.
6	RecognizeThirdPass	Third pass recognition operation. Used when IOcrPage.Recognize is called.
7	SaveDocumentPrepare	Prepare the document operation. Used when IOcrDocument.Save is called.
8	SaveDocument	Save document operation. Used when IOcrDocument.Save is called.
9	SaveDocumentConvertImage	Convert the document images operation. Used when IOcrDocument.Save is called.
10	Formatting	Format the document before saving. Used when IOcrDocument.Save is called.
11	RecognizeOmr	Recognizing OMR zones operation. Used when IOcrPage.Recognize is called on a page with zones containing OcrZoneType.Omr.

Remarks

OcrProgressOperation is the value of IOcrProgressData.Operation. Use this value to examine the current operation of the process.

Each operation listed represents one of the fundamental services provided by the OCR engine. Any application program will use at least some of these processes.

Each operation can be initiated by the methods shown. OcrProgressCallback can be used to generate progress monitoring on any of these operations.
