The rotation knob previously anchored to axis-aligned bounding boxes, so
under rotation or padding it floated in space, visually attached to
nothing. It now rides the actual top-right corner of the rotated image
quad (short stem, offset outward along the corner's radial direction)
and orbits with the image as the angle changes - the grab-the-object's-
corner model design tools use. Verified at 0/30/-60/135 degrees: the
drawn knob sits exactly at the computed rotated-corner position.
Feather quality of life: default is now 24 (a no-op until padding or
rotation creates generated area), and the slider is paired with a number
box with single-step arrows for granular control; both stay in sync and
values above the slider range remain typeable up to 4096.
The sidebar Preview now renders the feather fade live: it builds the
generated-area mask (padding, rotation corners, source alpha), blurs it,
draws it twice to match the engine's edge-pinned ramp, tints it with the
fill color, and overlays - so tweaking feather shows the real blend as
you type. Verified: preview pixels near the crop edge move measurably
toward the fill color as feather increases.
Review fixes verified against live ComfyUI 0.28.0:
- rotatedSize now reproduces Pillow's expand=True output exactly (transpose
fast path at axis angles, corner extents elsewhere). The previous formula
was 1px short on 34 of 78 sampled size/angle combos, so editor-predicted
output dimensions disagreed with queued results at most free angles.
Verified 0 mismatches across 6776 combinations and end-to-end on the
server (predicted 848x496 == queued image and mask at 77.7 degrees).
- decode_video_frame seeks to the nearest keyframe and decodes forward
instead of scanning from frame 0, with the sequential scan kept as the
fallback for files without usable timestamps. Scrubbing long videos no
longer decodes the entire prefix per preview request.
- Preview routes no longer serve arbitrary local paths to any HTTP client:
local-path previews outside ComfyUI's input/output/temp folders now
require AUSBOSS_TRANSFORM_LOCAL_PREVIEW=1, checked before touching the
filesystem so denied requests cannot probe path existence. Queued
workflows are unaffected.
- Editor: metadata is cached per source instead of refetched every scrub
tick, timeline seeks fetch only the frame with a 70ms trailing debounce,
AbortError from superseded requests no longer paints the error state,
and switching source mode before picking a file no longer resets the
transform.
- Tests: 13 -> 18 Python (seek vs sequential ground truth, time-mode seek,
out-of-range clamp, preview gate), 8 -> 9 JS (Pillow-verified rotated-size
fixtures including the odd/even transpose edge).
