[vtkusers] Translation of Image using vtkTransform

[Rakesh Patil]

 Hi,To be more precise, i want to implement this functionality as explained here.. http://www.codeproject.com/KB/dotnet/Calibrator.aspx?msg=2585113I have a GUI window, where there is facility to set three points and and mapp it to the geographic coordinates.. So how can i achieve this in VTK..??ThanksRegardsRakesh Patil Original message From:Jothybasu K Selvaraj< jothybasu at gmail.com >Date: 14 Apr 10 20:10:00Subject:Re: [vtkusers] Translation of Image using vtkTransformTo: "Eric E. Monson" Hey Rakesh,I didn't get your point clearly. If you only want to display the image at a different position you can use setPosition() as Eric said.Are yotrying to do something different?

If you use the output of a reader or some filter as the input to a vtkImageActor, then you can just do: imActor>Se
 tPosition(x,y,z);If you really want to change the origin of the image for some other calculation, then you can use vtkImageChangeInformation to modify the image properties.

I tried using vtkTransform, vtkTransformPolyDataFilter and vtkImageDataToPolyDataFilter.. But here it takes lot of time to convert image data to polydata..Any easier way to translate the image from its default position to user defined position..??ThanksRakesh PatilDear VTK !
