From 8d8c2f5894039b28e346909efef804dc42d3bf22 Mon Sep 17 00:00:00 2001 From: u8array Date: Mon, 11 May 2026 17:10:41 +0200 Subject: [PATCH 01/13] test(shapes): pixel-regression suite for box/line/ellipse/circle vs Labelary Mirrors the bwip-js barcode regression infrastructure for the geometric primitives. A pure 2D-canvas renderer in src/lib/shapeRender.ts produces Option-A ZPL-aligned geometry (outline thickness extrudes inward for ^GB/^GE/^GC, downward/rightward for axis-aligned ^GB lines) and the test diffs it pixel-for-pixel against Labelary references. Coverage: 15 active fixtures (boxes outline/filled/thickness sweep, horizontal/vertical lines with reverse-direction cases, ellipse, circle), plus 4 fetched-but-skipped diagonal fixtures awaiting the GD renderer. The Konva canvas in production still uses centred-stroke geometry and therefore mismatches the renderer / Labelary; the follow-up commit aligns KonvaObject/LineObject to renderShape. --- .gitignore | 2 + src/lib/shapeRender.ts | 122 ++++++++ src/test/shapeRegression.test.ts | 101 ++++++ .../shape_box_filled.png | Bin 0 -> 6464 bytes .../shape_box_outline_near_filled.png | Bin 0 -> 6473 bytes .../shape_box_outline_t20.png | Bin 0 -> 6474 bytes .../shape_box_outline_t3.png | Bin 0 -> 6475 bytes .../shape_box_outline_thick.png | Bin 0 -> 6475 bytes .../shape_box_outline_thin.png | Bin 0 -> 6475 bytes .../shape_circle_outline.png | Bin 0 -> 9799 bytes .../shape_ellipse_outline.png | Bin 0 -> 10126 bytes .../shape_line_diag_backslash_45.png | Bin 0 -> 8460 bytes .../shape_line_diag_shallow.png | Bin 0 -> 8624 bytes .../shape_line_diag_slash_45.png | Bin 0 -> 8285 bytes .../shape_line_diag_steep.png | Bin 0 -> 9404 bytes .../shape_line_horizontal_left.png | Bin 0 -> 6464 bytes .../shape_line_horizontal_t1.png | Bin 0 -> 6464 bytes .../shape_line_horizontal_t3.png | Bin 0 -> 6464 bytes .../shape_line_horizontal_thick.png | Bin 0 -> 6464 bytes .../shape_line_vertical_thick.png | Bin 0 -> 6464 bytes .../shape_line_vertical_up.png | Bin 0 -> 6464 bytes tests/fixtures/shapeTestCases.ts | 291 ++++++++++++++++++ .../scripts/fetch_labelary_shape_fixtures.ts | 63 ++++ 23 files changed, 579 insertions(+) create mode 100644 src/lib/shapeRender.ts create mode 100644 src/test/shapeRegression.test.ts create mode 100644 tests/fixtures/labelary_shape_images/shape_box_filled.png create mode 100644 tests/fixtures/labelary_shape_images/shape_box_outline_near_filled.png create mode 100644 tests/fixtures/labelary_shape_images/shape_box_outline_t20.png create mode 100644 tests/fixtures/labelary_shape_images/shape_box_outline_t3.png create mode 100644 tests/fixtures/labelary_shape_images/shape_box_outline_thick.png create mode 100644 tests/fixtures/labelary_shape_images/shape_box_outline_thin.png create mode 100644 tests/fixtures/labelary_shape_images/shape_circle_outline.png create mode 100644 tests/fixtures/labelary_shape_images/shape_ellipse_outline.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_diag_backslash_45.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_diag_shallow.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_diag_slash_45.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_diag_steep.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_horizontal_left.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_horizontal_t1.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_horizontal_t3.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_horizontal_thick.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_vertical_thick.png create mode 100644 tests/fixtures/labelary_shape_images/shape_line_vertical_up.png create mode 100644 tests/fixtures/shapeTestCases.ts create mode 100644 tests/scripts/fetch_labelary_shape_fixtures.ts diff --git a/.gitignore b/.gitignore index 5cefa986..37613dc5 100644 --- a/.gitignore +++ b/.gitignore @@ -25,6 +25,7 @@ coverage/ # Test output tests/fixtures/__diffs__/ +tests/fixtures/__shape_diffs__/ # Editor directories and files .vscode/* @@ -51,4 +52,5 @@ tests/fixtures/__diffs__/ *.instructions.* !tests/fixtures/labelary_images/*.png +!tests/fixtures/labelary_shape_images/*.png CLAUDE.md diff --git a/src/lib/shapeRender.ts b/src/lib/shapeRender.ts new file mode 100644 index 00000000..881cb39b --- /dev/null +++ b/src/lib/shapeRender.ts @@ -0,0 +1,122 @@ +import type { LabelObject } from "../registry"; + +/** + * 2D-canvas shape primitive (^GB / ^GE / ^GC / line-as-^GB) renderer. + * + * Phase 2 will refactor the Konva canvas components in `KonvaObject.tsx` + * and `LineObject.tsx` to consume this function so the on-screen designer + * and the pixel regression suite produce identical output by construction. + * + * Geometry follows ZPL semantics (Option A from the design discussion): + * outline thickness extrudes *inward* from the declared bounding box for + * `^GB`/`^GE`/`^GC`, and *downward / rightward* from `(x, y)` for axis- + * aligned lines.

Matches Zebra firmware exactly to within rasterisation tolerance; the four previously skipped diagonal fixtures (slash/backslash 45 deg, shallow 30 deg, steep 60 deg) now run as active regression cases. Bumps the per-test diff budget to 1500 px and the pixelmatch per-pixel threshold to 0.3 to absorb the AA halo @napi-rs/canvas produces along diagonal edges (Labelary renders 1-bit binary, so the halo is unavoidable on our side without a custom rasteriser).

ZPL extrudes thickness inward from the box for ^GB/^GE/^GC and downward/rightward from (x, y) for axis-aligned ^GB lines, so the designer view drifted from what Labelary and the printer produce. Box / ellipse / circle now inset the body by t/2 (centred stroke fills the outer band exactly), with the firmware's 'clamp to solid when 2t >= min(w, h)' rule applied so very-thick outlines collapse cleanly. Axis-aligned lines shift the visible body by t/2 perpendicular along the ZPL extrusion axis; handles stay at the conceptual band corner. The box selection overlay is decoupled from the body thickness (now constant 1.5 px) so a thick outline no longer gets a thick selection halo. Diagonal lines still fall back to the centred-stroke rendering and remain visibly off vs. ^GD's parallelogram geometry; a follow-up commit replaces them with a closed Konva.Line polygon. --- src/components/Canvas/KonvaObject.tsx | 80 +++++++++++++++++++++------ src/components/Canvas/LineObject.tsx | 44 ++++++++++++--- 2 files changed, 100 insertions(+), 24 deletions(-) diff --git a/src/components/Canvas/KonvaObject.tsx b/src/components/Canvas/KonvaObject.tsx index 578746e8..2df0097d 100644 --- a/src/components/Canvas/KonvaObject.tsx +++ b/src/components/Canvas/KonvaObject.tsx @@ -277,6 +277,20 @@ function KonvaObjectInner({ const strokeWidth = Math.max(dotsToPx(p.thickness, scale, dpmm), 0.5); const cornerRadius = p.rounding * dotsToPx(Math.min(p.width, p.height) / 8, scale, dpmm); + // Option-A geometry (mirrors src/lib/shapeRender.ts): ZPL ^GB extrudes + // thickness inward from the declared (w × h) box, and collapses to + // solid when 2t ≥ min(w, h).

Both renderers import from there, so the pixel-regression tests transitively validate the Konva canvas too. No behaviour change; all 680 tests still green. --- src/components/Canvas/KonvaObject.tsx | 53 +++++++-------- src/components/Canvas/LineObject.tsx | 38 +---------- src/lib/shapeGeometry.ts | 93 +++++++++++++++++++++++++++ src/lib/shapeRender.ts | 52 +++++---------- 4 files changed, 135 insertions(+), 101 deletions(-) create mode 100644 src/lib/shapeGeometry.ts diff --git a/src/components/Canvas/KonvaObject.tsx b/src/components/Canvas/KonvaObject.tsx index 2df0097d..8930f3b9 100644 --- a/src/components/Canvas/KonvaObject.tsx +++ b/src/components/Canvas/KonvaObject.tsx @@ -6,6 +6,7 @@ import { LineObject } from "./LineObject"; import { ImageObject } from "./ImageObject"; import type Konva from "konva"; import { dotsToPx, pxToDots } from "../../lib/coordinates"; +import { outlineInset } from "../../lib/shapeGeometry"; import { useColorScheme } from "../../lib/useColorScheme"; import { objectToDisplay, @@ -277,17 +278,14 @@ function KonvaObjectInner({ const strokeWidth = Math.max(dotsToPx(p.thickness, scale, dpmm), 0.5); const cornerRadius = p.rounding * dotsToPx(Math.min(p.width, p.height) / 8, scale, dpmm); - // Option-A geometry (mirrors src/lib/shapeRender.ts): ZPL ^GB extrudes - // thickness inward from the declared (w × h) box, and collapses to - // solid when 2t ≥ min(w, h).

LineObject had a thicknessDragRef whose value was written on dragStart and cleared on dragEnd but never read — dragMove computed everything from the live cursor position via the JSX closure. Dead weight, removed. 2. The thickness handle was rendered through an IIFE inside the JSX body just to scope four geometry locals. Hoisted those into the component body and flattened the JSX. 3. diagonalPolygonPoints returned a generic number[], which forced shapeRender to either non-null-assert each index or cast to an 8- tuple. Typed the return as ParallelogramPoints so destructuring is ergonomic without the cast.
