An edit made at the picture's own size loses whatever the model pushed
past the canvas edge, so realigning it left an empty strip on 13 of 16
held-out edits. Realign to Source now takes an optional stitcher: given
Load Image + Pad's stitcher for the padded canvas the edit was made on,
it measures inside the picture's area only and returns just that area,
so what the model drew into the margin fills the edges.
- A drift within half a pixel of a whole-pixel shift is cut straight
out of the edit with no resampling; an edit that already lines up
comes back untouched.
- The coarse pass also tries the edit at 0.86x-1.28x, so a large zoom
is found; models often reframe a padded canvas by zooming in to fill
it, and that zoom does not count toward Max zoom.
- The report says whether the frame was cut out or warped and names the
margin each side needed when an edit ran out of picture.
Load Image + Pad gains a mirror fill, which models read as more of the
scene: over 16 edits it provoked a reframe on 2, against 7 for edge
pixels and 5 for flat gray. The Qwen Image 2.1 Edit + Realign example
now edits on a 64 px mirror margin with the stitcher wired.
