The 0-based index of the detected table within the specified OCR result. It must be a value between 0 and GdPictureOCR.GetTableCount(OCRResultID) - 1.
The 0-based index of the cell's column in a detected table within the specified OCR result. It must be a value between 0 and GdPictureOCR.GetTableColumnCount(OCRResultID) - 1.
Returns the left x-coordinate of the column's bounding box, in pixels.
Returns the top y-coordinate of the column's bounding box, in pixels.
Returns the width of the column's bounding box, in pixels.
Returns the width of the column's bounding box, in pixels.

Parameters

OCRResultID
The unique result identifier of the executed OCR process obtained by the GdPictureOCR.RunOCR method.
TableIdx
The 0-based index of the detected table within the specified OCR result. It must be a value between 0 and GdPictureOCR.GetTableCount(OCRResultID) - 1.
ColummIdx
The 0-based index of the cell's column in a detected table within the specified OCR result. It must be a value between 0 and GdPictureOCR.GetTableColumnCount(OCRResultID) - 1.
Left
Returns the left x-coordinate of the column's bounding box, in pixels.
Top
Returns the top y-coordinate of the column's bounding box, in pixels.
Width
Returns the width of the column's bounding box, in pixels.
Height
Returns the width of the column's bounding box, in pixels.

Return Value

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