CleanNoise(CleanNoiseFlags,Int32,Int32,Int32) Method

Visual Basic
C#
Delphi
JScript
C++/CLI

'Declaration
 
Public Overloads Sub CleanNoise( _
   ByVal flags As CleanNoiseFlags, _
   ByVal sizeHorz As System.Integer, _
   ByVal sizeVert As System.Integer, _
   ByVal objectDistance As System.Integer _
)

'Usage
 
Dim instance As ImageEditor
Dim flags As CleanNoiseFlags
Dim sizeHorz As System.Integer
Dim sizeVert As System.Integer
Dim objectDistance As System.Integer
 
instance.CleanNoise(flags, sizeHorz, sizeVert, objectDistance)

public void CleanNoise( 
   CleanNoiseFlags flags,
   System.int sizeHorz,
   System.int sizeVert,
   System.int objectDistance
)

public procedure CleanNoise( 
    flags: CleanNoiseFlags;
    sizeHorz: System.Integer;
    sizeVert: System.Integer;
    objectDistance: System.Integer
);

public function CleanNoise( 
   flags : CleanNoiseFlags,
   sizeHorz : System.int,
   sizeVert : System.int,
   objectDistance : System.int
);

public:
void CleanNoise( 
   CleanNoiseFlags flags,
   System.int sizeHorz,
   System.int sizeVert,
   System.int objectDistance
)

Parameters

flags: Control flags to remove noise
sizeHorz: Maximum width of noise object in pixels
sizeVert: Maximum height of noise object in pixels
objectDistance: Maximum distance of noise object from an object that is large than sizeHorz or sizeVert

If flags parameter has marginsNoiseOnly set, then black noise is removed in margins only. Margins are areas adjacent to the edges of the image containing no objects larger than noise objects to be removed.
