[Insight-users] How does ITK divide image when multithreading?

std::endl;And my image is 100 by 100 in pixel, then will these 8 threads divide
the image into 8 pieces or patches?If so, for my 100 by 100 image, every patch
contains 1250 pixels, but now it is not a square image anymore. Does ITK put
this 1250 pixels into vectors to manipulate?Thanks very much!Aaron

Hi Aaron,

ThreadedGenerateData() must only work to generate the region passed to it.  You
can see how these regions are split by looking at SplitRequestedRegion in
itk::ImageSource.

It is important to use the itk iterator api to transverse these regions.

Matt
