public: GdPictureStatus SaveAsText(

)

public:
GdPictureStatus SaveAsText( 
   String^ OCRResultID,
   String^ FilePath,
   OCROutputTextFormat TextFormat,
   bool KeepLineBreaks
)

Parameters

OCRResultID: A unique result identifier of the executed OCR process obtained by the GdPictureOCR.RunOCR method. It specifies the OCR result you want to save.
FilePath: The path to the file where the result 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: 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.

Example

How to save the results to text files when processing the OCR on the same image with different settings.

VB.NET
C#
