Nine-slice and the sort line hung on the texture frame alone. Drawing
and sorting already read both off the TextureRef every picture hands
out, but the generated pictures always said "no slice, no line". So
the feature moves from the frame to the picture, without a second
copy of any rule.
- PictureCut (border, fill, sortLine) is one type. TextureFrame
extends it, PixelArtAsset and VectorArtAsset carry it as a whole.
The texture file format does not change, and no migration is needed.
- The rules in texture.ts take a cut and a size: cutSortLine,
setCutSlice, rawCutSlice and the rest replace the frame* versions.
serialize.ts reads all three through one readCut.
- cutTarget.ts resolves a target to cut and size: a texture frame, a
pixel frame's size or the vector canvas. It lives apart from
texture.ts because vectorart.ts reaches texture.ts itself.
- SetSliceCommand and SetSortLineCommand take that target instead of
(assetId, frameId). They refuse an asset that draws no picture.
- generatedRef fills slice and sortLine from the drawing. The whole
strip of a pixel art asset with several frames gets none, it is no
picture of that size. With one frame asset and frame are the same.
- Nine-slice scale is one shared schema row, now also on pixel art and
vector art.
- cutSection.ts holds the NINE-SLICE and SORTING rows once. The frame
inspector and the drawing inspector both build them.
- SheetCanvas draws a drawing's lines that are set, dashed as in the
Texture tab. They are not dragged there, the painting tools own the
canvas (as proposed in the issue).
- drawOrder falls back to the picture's height when a ref has no
rect, or a sort line on vector art would have been ignored.
Tests:
- Gate: 232 files, 3542 tests (+8: drawing-cut.test.ts, and vector
art in sort-by-y.test.ts). Three counter-proofs bite: no cut on a
drawing, a cut on the whole strip, no height fallback.
- e2e 48: 44 checks (+1, sum 1732). 48l-ii reads red and blue where
12-pixel borders at scale 2 put them. Without borders both spots
read green.
- Looked at: the Pixel art tab with the lines, and the sliced sprite.
