[Insight-users] What are the differences between GetLargestPossibleRegion and GetRequestedRegion?

[Dženan Zukić]

In short - no.

When the image is first read, it has requested=largest. However, you can set
requested region to some subset of the entire image, which is then respected
by all filters - this is to reduce computation burden by eliminating
computation of insignificant parts. If you don't do anything,
requestedRegion will always be equal to largest.

If I am wrong, can someone correct me please?
