(I'm using hugin 2014.0.0.51ff237f209e on Ubuntu 14.04)
I am attempting to stitch together a set of tiles. These tiles
tessalate, but also have a border.
So I'm setting control points on the corresponding corners,
and setting a mask to remove the borders (i.e. only include the middle).
I can't use the obvious "crop"
since some of the tiles have been photographed at an angle.
All this has gone well.
But the stitching/blending has gone very poorly.
Masking appears to not ... not work, or at least do something
I don't understand. The mask only seems to be applied
where the source images overlap.
In the attached sample, for example, the top-left image
retains its left and top border, only being masked on its
right and bottom edges.
This can be seen easily by doing
nona -m TIFF_multilayer -o tst hug.pto
And viewing the resulting multi layer tiff in Gimp.
If I let hugin (AKA enblend) stitch the images, I not only
get an unwanted border, but enblend goes a "little nuts"
if the masks areas don't quite touch. Pitch black pieces are created,
which leak and bleed a lot.
I attached a single image, and a pto. The 4 images in the pto
are simply copies of the one image.
