Stackreg zero padding issue

 Hi,
I raised a similar question on image.sc forums
https://forum.image.sc/t/stackreg-zero-padding/35129

We use Stackreg to align an image stack and try to apply the transformation
matrices obtained to another channel of the same image stack. We do rigid
registration of the image stack and stackreg does great. However, it also
does zero padding of some of the images in the stack. Now, when we apply
the transformation matrices (localTransform) obtained from StackReg to
another channel of the same stack, this zero padding does not happen and so
although the transformation matrices are applied, the 2 image stacks are
not aligned well.

Any idea how to resolve this issue?

Thanks
