<P class=MsoNormal><SPAN style="COLOR: black">I sent this yesterday but I don't know why it didn't apear in the forum. I'm sending it again, please can someone help me with it.</SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">I'm using vtkPicker to pick cells on an image and draw on the image. I've copied a short version of my program. I'm using vtkDotNet and managedItk. I want to draw lines through the picked points on a 2d tif image. Key 'p' is used to pick a point. The lines need to remain in the same place they've been drawn no matter zooming or rotating. The problem is :</SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">1- When I zoom the image and get the picked cell dimension, Z would be a value rather than 0 which I don't understand why.</SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">2- When I rotate the image and pick the points and draw lines. It seems they are in the right place but when I rotate the image the lines would be somewhere outside the image. </SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black"> </SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">I'm using picker.GetPickPosition() to get the dimension of the picked point. I'd probably need to change this. Does anyone know how I can fix the problem? Any suggestions would be a great help</SPAN></P>
