<DIV>Hi all,</DIV>
<DIV>I had asked this question before unfortunately, and now I am extending it with minor changes, but the problem is still the same. Please give me some clues, ideas, just anything that comes to your mind... </DIV>
<DIV> </DIV>
<DIV>What does it mean</DIV>
<DIV> </DIV>
<DIV>Description: itk::ERROR: PNGImageIO(026955F0): PNG Writer can only write 2-dimen<BR>sional images</DIV>
<DIV> </DIV>
<DIV>And yes I am asking for a 2D image as well ....??</DIV>
<DIV> </DIV>
<DIV>Here is the question: I am trying to use Qt+ITK to test some functions, so I want to define a public filter in Qt's main function which I will use as a buffer to hold my images, but I am getting an exception error (as above). I don't understand if my declerations are wrong, or if only the image writing stage is wrong or else...</DIV>
<DIV> </DIV>
<DIV>The output of my code is:</DIV>
<DIV> </DIV>
<DIV>This program resizes the input file with the following parameters<BR>x starting value: 300<BR>y starting value: 200<BR>x extension : 400<BR>y extension : 400<BR>===========================</DIV>

<DIV>I am copying parts of the code below from the header file and the c++ file. </DIV>

<DIV> cout << "images are cropped \n" << endl;</DIV>
<DIV> </DIV>
<DIV>//here I definitely know that cropMoving->GetOutput() gives correct results</DIV>
<DIV>//because I am able to save it as an image. However, I also want to save it in a</DIV>
<DIV>//public variable to use over and over.</DIV>
<DIV> </DIV>
<DIV>//here comes the part which fails:</DIV>

<DIV> RegionType regionGL;<BR> regionGL.SetSize(Width, Height);<BR> regionGL.SetIndex(0,0);</DIV>
<DIV><BR> filter = FilterType::New();<BR> filter->SetRegionOfInterest(regionGL);<BR> filter->SetInput( cropMoving->GetOutput());</DIV>

<DIV>//-------------------------------------------------------------------</DIV>
<DIV> </DIV>
<DIV>If I couldn't express my problem clearly, I am very sorry. I would be glad to send the whole project though... I will really appreciate it a lot if anyone could help me...</DIV>
<DIV>
<DIV>Thanks a lot !</DIV>
<DIV>Seniha</DIV>
<DIV> </DIV>
<DIV>PS: I have an idea that even if I got the previous code working, it will not do the thing I want, or will it? What should I do?</DIV>
