I think it's pretty generous to even call it organized, but thanks ;) > Does Multiblend look at the masks of the input images, or just the rectangular > bounding box the image?

It looks at the masks of each image, and first builds what I call the XOR map - showing only those areas where one image's pixels are present. From there the pixels spread outward and create a distance map (not a true Euclidean distance transform, but good enough). This is essentially what Enblend does (but it <i>does</i> use a true EDT), but seaming more than two images requires a bit of extra care to be taken. (actually the XORing and the first stage of the distance transform are combined, which makes for some tricky-to-read code) > The two nadir images don't have the exact yrp, but even so, preference has to > be given to one > image over the other. Ideally yes, but the choice may have to be arbitrary (as it would be in Enblend, since it would be determined by input order).

I should point out this isn't a general cure - some users may have to use lower (more negative) numbers, and this will affect how wide the blending is across the pano. I've had some ideas on other ways to deal with the boundary - one of them could give a "perfect" result but will require a lot of changes and may be inefficient (I love efficiency!) Is there someone who can change the title of this discussion, as multiblend is no longer Windows only?
