public void AutoCrop( 
   System.int leftMargin,
   System.int topMargin,
   System.int rightMargin,
   System.int bottomMargin
)

public procedure AutoCrop( 
    leftMargin: System.Integer;
    topMargin: System.Integer;
    rightMargin: System.Integer;
    bottomMargin: System.Integer
);

public function AutoCrop( 
   leftMargin : System.int,
   topMargin : System.int,
   rightMargin : System.int,
   bottomMargin : System.int
);

public:
void AutoCrop( 
   System.int leftMargin,
   System.int topMargin,
   System.int rightMargin,
   System.int bottomMargin
)

Parameters

leftMargin: New left margin in pixels
topMargin: New top margin in pixels
rightMargin: New right margin in pixels
bottomMargin: New bottom margin in pixels

{
    ImageEditor editor = new ImageEditor();

        // Do Processing
        editor.AutoDeskew();                // Use AutoDeskew before AutoRotate
        editor.AutoRotate();

        editor.SmoothCharacters();
        editor.CleanNoise(3);              // Remove only black pixels.  Use CleanNoiseExt to remove white noise
        // editor.CleanNoise(CleanNoiseFlags.black | CleanNoiseFlags.white, 3, 3, 10);
        editor.lineCurvature = LineCurvature.low;
        editor.lineMaxAngle = 5;
        editor.lineMaxGap = 5;
        editor.lineMinLength = 200;
        editor.DeleteLinesAndRepair(LineDirection.horzAndVert);
