[vtkusers] how to get the get the currently displayed image

[Willi Huber]

As far as I know of ImageResliceMapper doesn't do anything to your data. Therefore you just can use the input data.

If you want to write out the data with the new orientation according to the slicing plane set in ImageResliceMapper you better should use vtkImageReslice or you can obtain the slicingPlane of the mapper and do the math to set the axes in vtkImageReslice.

Best,
Willi

>>>hi folks, I need to get the currently displayed image and save it to a dicom file and I don't want to user vtkWindowToImageFilter, the problem with this filter is that it only save one slice (including annotations) and I need to save all slices in the current orientation. My orientations are set using the camera view up, this is an example pipeline:
