[Insight-users] Exception when execute update of a writer

[Antonio Gómez Barquero]

First of all, Thanks for replying! J

 

In this case, both, salida and ui.imageframe->imagereader are
'itk::Image<TPixel,VImageDimension>'. Then, as they are no filters, there no
method ‘GetOutput()’ to apply in this case. 

 

Now, I think that I should translate the image into a filter, I am thinking
about using the itk::ImportImageFilter, is this the best option?

 

Thanks !!

 

Antonio

Hi Antonio...

at first sight the code seems ok to me, perhaps the only odd thing is that
you store imagereader into salida (it seems that imagereader is a
(smart)Pointer to a itkFilter and you are using it as an input to writer.

 

If imagereader is a pointer to a filter, then  writer->SetInput( salida ) ;
should be  writer->SetInput( salida->GetOutput() ) ; instead

Hi all!

I have an image in an “itk::image<Pixeltype, 2>::Pointer salida”. I have
checked that it has the correct pixelvalues. I want to save the image into a
file, but in the last line, it gives me an exception and now I don’t know
what to do:

                // Saving the result into a file

                salida = ui.imageframe->imagereader;

                writer = itk::ImageFileWriter<ImageType>::New(); 

                writer->SetInput( salida ) ; 

                writer->SetFileName ( "output.jpeg");

                writer->Update();// ---> EXCEPTION!!

 

The exception goes to  xmtx.c  file ( mutex[mutual exclusion] support for
VC++), 

It goes to the last line of this part of the code:

 

_RELIABILITY_CONTRACT

void  __CLRCALL_PURE_OR_CDECL _Mtxlock(_Rmtx *_Mtx)

                {              /* lock mutex */

#ifdef _M_CEE

                System::Threading::Thread::BeginThreadAffinity();

#endif

                EnterCriticalSection(_Mtx);

                }

 

Does any of you have had the same problem? Any hint for fixing it?

 

Thanks in advance
