With Resize on, Image Crop + Rotate + Pad and both Video Crop + Rotate +
Pad nodes resized the padded canvas as one picture. Along every seam that
mixed fill into the picture and left the mask part on, part off. A hard
paste (stitch blend 0) kept that column as a faint line, and a band under a
pixel wide after the resize came out as nothing but that column: 1 px of
padding at a 0.62 scale left a line in the stitched result whatever the
model painted.
resize_then_pad (nodes/_transform_engine.py) resizes only the picture, with
the chosen method, into the box it has on the resized canvas, and puts the
fill around it. Bands are whole pixels, the picture's edge is picture, and
a band that comes to under half a pixel is left out. The mask is 1 on the
fill; inside the box it is the transform's own mask there (the feather's
ramp, the corners of a turn, see-through parts), resized bilinear with the
picture. The prompt view is placed the same way.
The box is transform_picture_box (nodes/_inpaint_crop_helpers.py), which
the stitcher now uses for its source bbox too, so the paste and the bbox
cannot disagree. It is never empty.
The output size is unchanged. With Resize off, or with no padding, image
and mask are bit for bit what they were. With padding, the picture can sit
up to half a pixel from where it did.
