GdPicture14 Namespace / GdPictureOCR Class / SaveAsText Method / SaveAsText(String,Stream,OCROutputTextFormat,Boolean) Method
A unique result identifier of the executed OCR process obtained by the GdPictureOCR.RunOCR method. It vthe OCR result you want to save.
A Stream object where the result will be saved to. This Stream object must be initialized before it can be sent into this method and it should remain open for subsequent use.
The text format of the output text file. A member of the OCROutputTextFormat enumeration.
The flag indicating whether to keep line breaks or not when saving the result.

Parameters

OCRResultID
A unique result identifier of the executed OCR process obtained by the GdPictureOCR.RunOCR method. It vthe OCR result you want to save.
Stream
A Stream object where the result will be saved to. This Stream object must be initialized before it can be sent into this method and it should remain open for subsequent use.
TextFormat
The text format of the output text file. A member of the OCROutputTextFormat enumeration.
KeepLineBreaks
The flag indicating whether to keep line breaks or not when saving the result.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks
The output stream should be open for writing and should be closed/disposed by the user as well.
