This method reduces the image noise in raster images.
Parameters
mode
Sets the mode of noise reduction (0: Median
luminance method, 1:Noise reduction for each RGB plane)
level
Sets the level of noise reduction for the RGB
mode (from 0 to 255, effective when Mode is 1)
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The RemoveNoise method reduces the image noise in raster images. When Mode is 1, the value of the level is enabled. As the Level parameter value increases the level of noise decreases.
To execute the RemoveNoise method, set the image handle of the image in the Image property or the Layer(LayerNumber).Image property. The RemoveNoise method supports 1, 4, 8, 16, 24, and 32 bit images and 8 bit grayscale images.
Before executing the RemoveNoise method, you must set the area on the image that will be affected. There are 4 ways to do this.
- To use a mask image, set the SelectMode property to EffectMask. Set the mask image handle in the SourceMask property
- To process the total image, set the SelectMode property to EffectAll
- To process the polygonal area on the image, set the SelectMode property to EffectPolygon. Select the polygon by setting the appropriate coordinate values for the points of the polygon in the Point property
- To process an elliptical area on the image, set the SelectMode property to EffectEllipse. Select the ellipse by setting the appropriate values for the bounding rectangle in the Rect property
When the SelectMode property is set to EffectPolygon or EffectEllipse, the appropriate values must be set in the Inside property.
If the RemoveNoise method is successful and the DestinationAsImageKitImage property is True, the resulting image will be set in the Image property or in the Layer(LayerNumber).Image property, according to the value set in the LayerNumber property.
If the RemoveNoise method is successful and the DestinationAsImageKitImage property is False, the resulting image will be set in the DestinationImage property.
