[Insight-users] Question about setRegions

[Yili Pan]

Hi everyone:

I'm trying to get a specific slice of the volume:

                        index[0]=sliceNum;
ImageType::RegionType regionImg;
ImageType::IndexType start;
start[0]=0;
start[1]=0;
ImageType::SizeType sizeImg;
sizeImg[0]=size[1];
sizeImg[1]=size[2];
regionImg.SetIndex(start);
regionImg.SetSize(sizeImg););
image->SetRegions(regionImg);
image->Allocate();
Then I use getPixel and setPixel to read the pixel value of volume and set
the value of  corresponding  position.
This method worked, but when I tried to write it as a function, the problem
came.
The program broke at image->SetRegions(regionImg)

Could you help me with this problem? If I write it in the main function, the
whole program would be very long

Thanks a lot!!

Best,
Yili
