[Insight-users] Copying an Image Object

[Luis Ibanez]

Hi Puja,


    im2->CopyInformation( im1 );

Will copy the following data from one
image to another:

1) LargestPossibleRegion
2) Origin
3) Spacing

This seems to be the method you need.

Note that there is no memory allocation
done here. So you may want to do something
like

m2->SetRegions( m1->GetLargestPossibleRegion() );
m2->Allocate();
m2->CopyInformation( m1 );

It is arguably if the first of these lines
should use GetBufferedRegion() instead of
GetLargestPossibleRegion().


Please let us know if you have further questions


Thanks



   Luis
