Hello,<br><br>I am beginner in using itk and I am trying to get the pixel value of a 2D image. As a first step, I am trying to create my own image object, to initialize and allocate the image region, and finally using the itkIndex to get and set a pixel value (knowing that is not the fastest method). I have written the following code, which is correctly built using VisualStudio2010 and Cmake. But when I run the .exe file with the Command Prompt window, I don't get any result on my screen. Could somebody tell me what to do to get some results? <br>
In the second step, I would like to set the filename of the image myself, using the Command Prompt window. Could somebody tell me what to change in my code, not only in the .cxx file but also in thr CMakeLists.txt?<br><br>
Thanks in advance<br><br>---------------------------------code-----------------------<br>------------------------------------------------------------<br><br>#if defined(_MSC_VER)<br>#pragma warning ( disable : 4786 )<br>#endif<br>
