Parameters

OCRResultIDs
A collection of the unique OCR result identifiers. It specifies the OCR results you want to save.
FilePath
The path to the file where the results will be saved. If the specified file already exists, it will be overwritten.
TextFormat
The text format of the output text file. A member of the OCROutputTextFormat enumeration.
KeepLineBreaks
