[vtkusers] how to work with imagedata

[h0ppel]

hi,

I've created imagedate on this way:

            vtkImageData myImage = new vtkImageData();
            myImage.SetDimensions(1392, 1040, 1);
            myImage.SetSpacing(1, 1, 1);
            myImage.SetOrigin(0, 0, 0);
            myImage.SetNumberOfScalarComponents(1);
            myImage.SetScalarTypeToFloat();
            myImage.AllocateScalars();
            myImage.GetPointData().SetScalars(vtkArray);

It works fine and in the viewer the picture look perfect...
but how can I work with this picture without saving befor?

vor example displaying the picture in a renderwindow
nowI see nothing... I think I need to interpret the pixel values first
like in the viewer.

thanks
