Public Function ShowMagnifier(Visible As Boolean, x As Long, y As Long, Scale As Double) As Boolean
public bool ShowMagnifier(bool Visible, int x, int y, double Scale)
Parameters
Visible
Sets the display of the magnifier
window: True (nonzero) displays the magnifier, False (0) hides the
magnifier
x, y
Sets the location of the center of
the magnifier (in pixels)
Scale
Sets the magnification of the display
in the magnifier (actual size display = 1.0)
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The ShowMagnifier method displays a magnifier in the ImageKit Control. The Height and Width properties determine the size of the magnifier and must be set.
When the Visible parameter = False, the x, y, and Scale parameter values are ignored.The magnifier will be displayed on the image when that image's ShowImage property is set to True. The order in which images are displayed are: base image, layer images (from smallest to largest index).
Note that if the base image has not been set then the layer images are not displayed. The ToolTip property is set to the values other than LengthUnit.None, then the magnifier isn't displayed.
Example
Sample code for displaying the magnifier:
[Visual Basic.NET]
Private Sub ImageKit1_MouseMoveImage(ByVal sender As Object, ByVal e As Newtone.ImageKit.Win.ImageKit.MouseUpDownEventArgs) Handles ImageKit1.MouseMoveImage
ImageKit1.Magnifier.Width = 100
ImageKit1.Magnifier.Height = 100
ImageKit1.Magnifier.Type = Newtone.ImageKit.Win.MagnifierType.RectangleMagnifier
ImageKit1.Magnifier.Border = True
ImageKit1.Magnifier.ShowMagnifier(True, e.X, e.Y, 2)
End Sub
[Visual C#.NET]
private void imageKit1_MouseMoveImage(object sender, Newtone.ImageKit.Win.MouseUpDownEventArgs e)
{
imageKit1.Magnifier.Width = 100;
imageKit1.Magnifier.Height = 100;
imageKit1.Magnifier.Type = Newtone.ImageKit.Win.MagnifierType.EllipseMagnifier;
imageKit1.Magnifier.Border = true;
imageKit1.Magnifier.ShowMagnifier(true, e.X, e.Y, 2);
}
