This method creates a mosaic effect on a raster image.
[Visual Basic]   [ Boolean = ]imagekitcontrolname.Effect.Mosaic(x As Long, y As Long, Points As Long, Width As Long, Height As Long)
[Visual C++]     [ BOOL = ]imagekitcontrolname.GetEffect().Mosaic(long *x, long *y, long Points, long Width, long Height)

Parameters

Name Explanation
x An array of x coordinate values defining points of a polygonal area on the image. (in pixels) *
y An array of y coordinate values defining points of a polygonal area on the image. (in pixels) *
Points The number of points defining the polygonal area on the image.
Width The width of the mosaic (in pixels)
Height The height of the mosaic (in pixels)
*
In Visual C++, pass the pointer to the first element in the x and y arrays.
In Visual Basic, the arguments are returned in the first elements of the arrays x(0) and Y(0).

Return Value

Returns True (nonzero) if successful, otherwise returns False (0).

Explanation

The Mosaic method creates a mosaic effect on a raster image. To execute the Mosaic method, set the image handle of the image in the ImageHandle property or the Layer(LayerNo).ImageHandle property. The Mosaic method supports 1, 4, 8, 16, 24, and 32 bit images.

Before executing the Mosaic method, you must set the area on the image that will be affected. There are 4 ways to do this.

  1. To use a mask image, set the SelectMode property to 0. Set the mask image handle in the MaskImageHandle property
  2. To process the total image, set the SelectMode property to 1
  3. To process the polygonal area on the image, set the SelectMode property to 2. Select the polygon by setting the appropriate coordinate values for the points of the polygon in two arrays, one array for the x coordinate values and one array for the y coordinate values. The pass these arrays to the x and y arguments of the Mosaic method. The number of points defining the polygon must be 3 or more
  4. To process an elliptical area on the image, set the SelectMode property to 3. Select the ellipse by setting the appropriate values for the bounding rectangle in the RectLeft, RectTop, RectRight, and RectBottom properties

When the SelectMode property is set to values other than 2 (ikEffectPolygon), please set dummy arrays in the x and y parameters and set the Points parameter to 0.
When the SelectMode property is set to 2 or 3, the appropriate value must be set in the InOut property. If successful the resulting raster image data is set in the LayerNo property (the ImageHandle property or the Layer(LayerNo).ImageHandle property. If unsuccessful, 0 is returned.

When the Caption, Message, and ButtonName properties are blank, the progress dialog box will not be displayed. When the progress dialog box is displayed, the percentage that the processing has completed will be shown in the dialog box.
