Hi Larry, I did try the ImageBufAlgo.over() but I believe I need to specify a region (roi) to make it work, as the EXR background/canvas is not always black for the slices I'm trying to merge (or composit together). Please see these example slices: https://www.dropbox.com/sh/9if7mm2plvyffum/AAAu1kmGml24q-ZD9r4ovzJMa/email/oiio_ImageBufAlgo
My problem is the number of slices and their size can vary, so I was hoping I could somehow detect the roi / region and then specify that in ImageBufAlgo.over(). Perhaps that should have been my initial question. Is that possible, and if so how can the roi be detected for the attached slice#.exr files? The result.exr in the Dropbox link is what I would like to end up with. // Fredrik On Fri, Jun 20, 2014 at 12:23 AM, Larry Gritz <[email protected]> wrote: > There is an ImageBufALgo.over().
