Yeah, it's a bit non-obvious. If I recall correctly, each mask is the seam between the blended image *so far* and the next input image.
So the first mask will be the seam between images 1 and 2, then the next mask is the seam between (1+2) and 3, then (1+2+3) and 4... and so on. If you can make sure your top-left most image is the first image, you may be more successful in overlaying them. Unfortunately, because of the sequential way enblend blends, it's possible to get counterintuitive things happening like seams crossing over each other. Shameless plug, but <a href="http://horman.net/multiblend/">multiblend</a> exists partly to remedy that deficiency (see "Consistent and integrated seaming"). It's also able to save out a single seam map, which can be easily overlaid onto the result. The one thing (okay, just the main thing) it *doesn't* do is optimise seams. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
