<br>
Regarding the ExtractImageFilter, this is an expected result. As you can read here, <a href="http://www.itk.org/Doxygen/html/classitk_1_1ExtractImageFilter.html" rel="noreferrer" target="_blank">http://www.itk.org/Doxygen/html/classitk_1_1ExtractImageFilter.html</a> , setting the collapse direction is mandatory. The default setting is "Unknown" and the filter will not run correctly.<br>
<br>
So I suggest you add:<br>
extracter->DirectionCollapseToIdentity();<br>
<br>
This should works.<br>

Hi,<br>
<br>
I know the input and desired regions, not sure how to look for the buffered region.<br>
<br>
1. Reviewing my code I saw I didn't set the input image for the extracter, so I added:<br>
extracter->SetInput(image);<br>
<br>
Good, right? But no. Still the same error.<br>
<br>
2. Then I tried switching to itkExtractImageFilter, and I got:<br>
Exception at 0x7633c42d, code: 0xe06d7363: C++ exception, flags=0x1 (execution cannot be continued) (first chance) at c:\itk-4.8.0-installed\include\itk-4.8\itkextractimagefilter.hxx:242<br>
<br>
So I had to look inside this code (why don't throw me more info in the try catch?) to see what's happening, and I read this:<br>
</span>itkExceptionMacro ( << " It is required that the strategy for collapsing the direction matrix be explicitly specified. " << " Set with either myfilter->SetDirectionCollapseToIdentity() or myfilter->SetDirectionCollapseToSubmatrix() " << typeid ( ImageBase< InputImageDimension > * ). name () );<br>
<div><div class="h5">3. I also tried to insert a:<br>
image->Update();<br>
or<br>
image->UpdateOutputData();<br>
with same results.<br>
<br>
I was thinking about passing the reader, but I'd like to apply changes to my image, so this method would receive a modified copy (no DeepCopy method like in vtk?)<br>
<br>
<br>
Yes, the input image is connected to a pipeline:<br>
itk::Image -> itk:: ImageToVTKImageFilter -> vtk:: vtkImageFlip -> vtkImageData -> vtkImageViewer2<br>
<br>
<br>
Thanks again for your interest.<br>

Hello,<br>
<br>
What is the buffered region for the input image? Is the input image connected to a pipeline?<br>
<br>
Perhaps you just forgot to update the input image before running this function?<br>

Hi,<br>
<br>
I have a method that was exporting fine one frame from my itk::Image.<br>
<br>
My method:<br>
<br>
void Exporter :: exportOriginal ( QString fileName , ImageType :: Pointer image , int frame )<br>
{<br>
typedef itk :: ImageFileWriter < FrameImageType > WriterType ;<br>
WriterType :: Pointer writer = WriterType :: New ();<br>
<br>
writer -> SetFileName ( fileName . toStdString (). c_str ());<br>
<br>
ImageType :: RegionType inputRegion = image -> GetLargestPossibleRegion ();<br>
<br>
ImageType :: IndexType index = inputRegion . GetIndex ();<br>
ImageType :: SizeType size = inputRegion . GetSize ();<br>
<br>
index [ 0 ] = 0 ;<br>
index [ 1 ] = 0 ;<br>
index [ 2 ] = frame ;<br>
<br>
// 3D to 2D<br>
size [ 2 ] = 0 ;<br>
<br>
ImageType :: RegionType outputRegion ;<br>
outputRegion . SetIndex ( index );<br>
outputRegion . SetSize ( size );<br>
<br>
</div></div>typedef itk :: Testing :: ExtractSliceImageFilter < ImageType , FrameImageType > ExtractType ;<br>
<div><div class="h5">ExtractType :: Pointer extracter = ExtractType :: New ();<br>
extracter -> SetExtractionRegion ( outputRegion );<br>
<br>
writer -> SetInput ( extracter -> GetOutput ());<br>
try<br>
{<br>
writer -> Update ();<br>
}<br>
catch ( itk :: ExceptionObject & ex )<br>
{<br>
std : cerr << ex << std :: endl ;<br>
}<br>
}<br>
<br>
as inputRegion, I have:<br>
index: [0, 0, 0]<br>
size: [512, 512, 12]<br>
<br>
as outputRegion, I have:<br>
index: [0, 0, 1] # first frame<br>
size: [512, 512, 0]<br>
<br>
<br>
<br>
But I'm not sure what happened, now with every image I got an exception:<br>
itkimagefilewriter.hxx:287: " Largest possible region does not fully contain requested paste IO region "<br>
<br>
By the way, my try catch is not getting the exception message, I had to look inside the writer class.<br>
Any ideas? Thank you.<br>
