# I am new to slicer,  after applying linear transform to a 3D images and save it on my local computes the images seems to be same as untransformed or original image is there a way I can save a transformed images

Hardening with an affine only changes the header, not the pixels.

See this thread for more info:

> I have tried “hardening” the transformation and saving it. The saved images are in their native coordinate spaces and orientations. Is there a way to save them all regridded to the same 3D matrix? Sorry if this is an obvious question, but I can’t seem to find how to do this in the documentation. The data is all registered and ready to go. I have been meaning to learn Python, but don’t have time today to jump in. Thanks, Nathan
