CleanNoiseExt Method (CiRepair)

Visual Basic
C#
Delphi
JScript
C++/CLI

'Declaration
 
Public Function CleanNoiseExt( _
   ByVal Flags As ECleanNoiseFlags, _
   ByVal maxNoiseSizeHorz As System.Integer, _
   ByVal maxNoiseSizeVert As System.Integer, _
   ByVal minObjectDistance As System.Integer, _
   ByVal reserved0 As System.Integer _
) As System.Integer

'Usage
 
Dim instance As CiRepair
Dim Flags As ECleanNoiseFlags
Dim maxNoiseSizeHorz As System.Integer
Dim maxNoiseSizeVert As System.Integer
Dim minObjectDistance As System.Integer
Dim reserved0 As System.Integer
Dim value As System.Integer
 
value = instance.CleanNoiseExt(Flags, maxNoiseSizeHorz, maxNoiseSizeVert, minObjectDistance, reserved0)

public System.int CleanNoiseExt( 
   ECleanNoiseFlags Flags,
   System.int maxNoiseSizeHorz,
   System.int maxNoiseSizeVert,
   System.int minObjectDistance,
   System.int reserved0
)

public function CleanNoiseExt( 
    Flags: ECleanNoiseFlags;
    maxNoiseSizeHorz: System.Integer;
    maxNoiseSizeVert: System.Integer;
    minObjectDistance: System.Integer;
    reserved0: System.Integer
): System.Integer;

public function CleanNoiseExt( 
   Flags : ECleanNoiseFlags,
   maxNoiseSizeHorz : System.int,
   maxNoiseSizeVert : System.int,
   minObjectDistance : System.int,
   reserved0 : System.int
) : System.int;

public:
System.int CleanNoiseExt( 
   ECleanNoiseFlags Flags,
   System.int maxNoiseSizeHorz,
   System.int maxNoiseSizeVert,
   System.int minObjectDistance,
   System.int reserved0
)

Parameters

Flags
maxNoiseSizeHorz: Maximum width of noise object in pixels
maxNoiseSizeVert: Maximum height of noise object in pixels
minObjectDistance: Maximum distance of noise object from an object that is large than maxNoiseSizeHorz or maxNoiseSizeVert
reserved0: Set to 0

If Flags has ciCnxMarginsNoise 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.
