How to make the output size of imwarp the same as the input?

I have some 3D images and wish to perform some rigid transform on them and keep the input size and output size the same. I used the imwarp function for these operations. But I found that it seems impossible to directly give parameters to ensure that the input and output have the same size as functions such as imrotate. How should I deal with it?
(Theoretically I can also crop or pad by myself, but sometimes the size of the image has an odd number, which makes it difficult to define the transformation by myself.)
