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) * |
| xSize | Sets the width of each glass tile (from 10 to 100) |
| ySize | Sets the height of each glass tile (from 10 to 100) |
| * 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 GlassTile method produces an effect similar to glass
tile on the image. This method is recommended when using scripting
or other languages that require variant types.
To execute the GlassTile method, set the image handle of the
image in the ImageHandle
property or the Layer(LayerNo).ImageHandle
property. The GlassTile method supports 8-bit grayscale, 16,
24, and 32 bit images.
Before executing the GlassTile 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 0. Set the mask image handle in the MaskImageHandle property
- To process the total image, set the SelectMode property to 1
- 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 GlassTile method. The number of points defining the polygon must be 3 or more
- 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.
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.
