how to get a region by mouse click

[newuser12342]

Hi,

I am using C# .net. I want to use the mouse to select a region from the source image for mask. How can I get the Left, Top, Width, Height values by mouse selected on the source image.

axCWIMAQViewer.Regions.RemoveAll();

axCWIMAQViewer.Region.GetRegionData(); //????

Greetings.

Look in google and search for mouse coordinate - you find something like that

http://www.mycsharp.de/wbb2/thread.php?threadid=61761

   Private Sub Form2_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
        Dim x, y As Integer

        x = Me.MousePosition.X - (Me.Location.X + 4) '+4 wegen den rändern der form
        y = Me.MousePosition.Y - (Me.Location.Y + 30) '+30 wegen der titelleiste und dem unteren rahmen

        Form1.PictureBox1.Location = New System.Drawing.Point(x, y)
    End Sub

Or use this:

Control.PointToScreen und Control.PointToClient

When i create a mouse event in my Visual Studion 2005 C# project i can work with x and y values:

private void axCWIMAQViewer1_MouseDownEvent(object sender, AxNationalInstruments.CWIMAQControls._DCWIMAQViewerEvents_MouseDownEvent e)

{

e.x                                        //x  coordinates 

}

Please give me feedback if the help suggestions help you to work with mouse coordinates

hi there,

I use  axCWIMAQViewer1_MouseDownEvent, axCWIMAQViewer1_MouseMoveEvent, axCWIMAQViewer1_MouseUpEvent to get the ROI by mouse selected.

It works fine.

Thanks for the info.

Greetings.
