[vtkusers] Problem with vtkImageAppend

[Sven Olaf Lüttmann]

Hey guys,

I'm reading DICOM images into a std::vector of vtkImageData to apply
some image processing.

Now I like to take those images stored in the vector and append them
using vtkImageAppend to get an 3D Image (Volume data).

The problem that occurred is, when I apply visualisation Techniques like
ray casting my volume is mirrored along the y-Axis. So everything is
just inverted.

As far as figured out the source must be the vtkImageAppend cause if I
use vtkDICOMImageReader for instance everything works just fine.

My Code looks like:

if(!this->imageAppend)
		this->imageAppend = vtkSmartPointer<vtkImageAppend>::New();
	
this->imageAppend->SetAppendAxis(2);

for(int i=0; i < this->vtkImageSeriesContainer.size(); i++)
{
	this->imageAppend->SetInput(i, this->vtkImageSeriesContainer.at(i));
}
this->imageAppend->Update();

Any ideas on that???

Thanks for help

Cheers
Sven
