<p class=MsoNormal><span lang=EN-US 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><span lang=EN-US><o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US 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><span lang=EN-US><o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='color:black'>2- When I rotate the
