ClearTesseractOCR

OCR, configuration

Description

Releases the provider created by ConfigureTesseractOCR on this instance

Syntax

Delphi

Procedure TPDFlib.ClearTesseractOCR;

ActiveX

Function PDFlib::ClearTesseractOCR() As Long

DLL

int DLClearTesseractOCR(int InstanceID);

Return values

Delphi has no return value; DLL and ActiveX return 1 after clearing the owned provider

Remarks

The callback is cleared only when OnOCRPage still refers to the owned provider

If an application assigned a different callback after configuring Tesseract, that callback is retained and its object is not freed

Calling this method repeatedly is safe; instance destruction performs the same owned-provider cleanup

Existing OCR text layers in the document are retained
