Re: [mitk-users] AccessByItk_n

Note that if you declare the image argument as 'const', only a read lock
will be applied. In case you are just reading the image but get this error,
you should check the constness of your function arguments.

Hope it helps.

Hello,It seems as the image was already locked by another access (by an accessor for example) and the lock is not released before you try to lock it again.Yann--

Hi Nil,

the image is locked by another accessor (see [1]). You may step into 
ImageAccessorBase or similar to understand who is blocking the image access.

Best,
Stefan

[mitk-users] AccessByItk_n

[Nil Goyette]

Hi all,

I have this error: "Prohibited image access: the requested image part is 
already in use and cannot be requested recursively!" and I'm not sure 
what it means. It's caused by the AccessByItk_n in 
mitkCorrectorAlgorithm.cpp in GenerateData().

I did modify the [old] segmentation plugin  so I'm probably to blame 
here. I replaced all mitk::LabelSetImage usages with mitk::Image because 
the plugin can do nothing with them anyway. Everything still works as it 
should except the +/- Correction button.

I tried reducing the number of  smart pointers pointing to 
m_WorkingImage but GenerateData() itself makes it go up by one so I 
don't see how I could make it stay at 1 in my own code. Any ideas what I 
can do to fix this?

Nil
