This method creates a mosaic effect on a raster image.
Public Function Mosaic(xSize As Integer, ySize As Integer) As Boolean
public bool Mosaic(int xSize, int ySize);
Parameters
xSize
The width of the mosaic (in
pixels)
ySize
The height of the mosaic (in
pixels)
Return Value
Returns True if successful. Returns False if unsuccessful.
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 SourceImage property. The Mosaic method supports 1, 4, 8, 16, 24, and 32 bit images.
If both of the values set in the XSize and YSize parameters are less than 1, this method does not produce an mosaic effect on a raster image.
Before executing the Mosaic 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 successful the resulting raster image data is set in the DestinationImage property.
