Re: How to get full size image which is transformed by warp function
Hi Stefan, Thank you very much for your suggestion. I am trying to figure out how to add in a certain amount of translation for different transforms. Thanks Yongda On Tuesday, June 18, 2013 12:24:46 AM UTC-7, Stefan van der Walt wrote:

Even after setting up output_shape parameter, it still lost part of image which is transformed to negative coordinates.
I'd represent the rotation as a transformation matrix, and then also add in a certain amount of translation to account for the negative coordinates. I believe this is what Johannes also recommended, and what is coded up in `skimage.transform.rotate`.
