SaveAsText(String,Stream,OCROutputTextFormat,Boolean) Method
Saves the provided OCR result, identifiable by its unique ID, to a stream in the text format.
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.
