Members
| Member | Description |
|---|---|
| FindZones | Page-layout decomposition operation. Used when IOcrPage.AutoZone is called. |
| Formatting | Format the document before saving. Used when IOcrDocument.Save is called. |
| 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. |
| ProcessImage | Image preprocessing operation. Used when IOcrPage.AutoPreprocess is called. |
| RecognizeFirstPass | First pass recognition operation that may be used when IOcrPage.Recognize is used with the MOR recognition module |
| RecognizeOmr | Recognizing OMR zones operation. Used when IOcrPage.Recognize is called on a page with zones containing OcrZoneFillMethod.Omr. |
| RecognizeSecondPass | Second pass recognition operation. Used when IOcrPage.Recognize is called. |
| RecognizeThirdPass | Second pass recognition operation. Used when IOcrPage.Recognize is called with OcrZoneRecognitionModule.OmniFontPlus3WayVoting is enabled. |
| SaveDocument | Save document operation. Used when IOcrDocument.Save is called. |
| SaveDocumentConvertImage | Convert the document images operation. Used when IOcrDocument.Save is called. |
| SaveDocumentPrepare | Prepare the document operation. Used when IOcrDocument.Save is called. |
| SaveImage | Image save operation. Used when IOcrPage.Recognize is called. |
Example
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.
