Hi,

I am using Leadtolos 17.5 with C# in WPF.

I want functionality to create Fullscreen CrossHair Cursor. I  have used following code in Winforms but not able do the same in WPF.
=======================================================

 Region r = new Region();
                    r.Union(new Rectangle(0, lastY, _view.ControlWidth, 1));
                    r.Union(new Rectangle(lastX, 0, 1, _view.ControlHeight));
                    _view.PrpRasterImageViewer.Invalidate(r);
                    _view.PrpRasterImageViewer.Update();
                    Graphics g = _view.PrpRasterImageViewer.CreateGraphics();
                    Pen p = new Pen(Color.Black, 1);
                    p.DashStyle = DashStyle.Dash;

                    g.DrawLine(p, 0, e.Y, _view.ControlWidth, e.Y);
                    g.DrawLine(p, e.X, 0, e.X, _view.ControlHeight);
                    lastX = e.X;
                    lastY = e.Y;

===============================================

Please help me . Thanks in advance

Can you send me a small working WinForms project (not your full application) that shows how exactly you are creating the cross hair cursor?

Thanks,

Hi Maen,

WinForm project is attached, Please have a look. I have used mouse move event to to display cursor. you just need to change the "rasterImagePath" value to see the cursor.

Please let me know if you have any question.

Thanks

You can draw the cross hair cursor in WPF by using the following code:

- XAML:
+-----------------+
<Grid Name="myGrid">
<Leadtools_Windows_Controls:ImageViewer x:Name="imageViewer1" Width="NaN" Height="NaN" MouseMove="imageViewer1_MouseMove" />
</Grid>
+-----------------+

- Drawing the cross hair cursor:
+-----------------+
Line myLine = new Line();
myLine.Stroke = System.Windows.Media.Brushes.LightSteelBlue;
myLine.X1 = imageViewer1.PhysicalSize.Width / 2;
myLine.X2 = imageViewer1.PhysicalSize.Width / 2;
myLine.Y1 = 0;
myLine.Y2 = imageViewer1.PhysicalSize.Height;                
myLine.Stroke = Brushes.LightSteelBlue;
DoubleCollection dashes = new DoubleCollection();
dashes.Add(2);
dashes.Add(2);
myLine.StrokeDashArray = dashes;
myLine.StrokeDashCap = PenLineCap.Round;
                 
Line myLine2 = new Line();
myLine2.Stroke = System.Windows.Media.Brushes.LightSteelBlue;
myLine2.X1 = 0;
myLine2.X2 = imageViewer1.PhysicalSize.Width;
myLine2.Y1 = imageViewer1.PhysicalSize.Height / 2;
myLine2.Y2 = imageViewer1.PhysicalSize.Height / 2;
myLine2.Stroke = Brushes.LightSteelBlue;
DoubleCollection dashes2 = new DoubleCollection();
dashes2.Add(2);
dashes2.Add(2);
myLine2.StrokeDashArray = dashes2;
myLine2.StrokeDashCap = PenLineCap.Round;

myGrid.Children.Add(myLine);
myGrid.Children.Add(myLine2);
+-----------------+
