From d813c22df571173ce4805c3821e05a36a17d7af1 Mon Sep 17 00:00:00 2001 From: Jan-Henrik Bruhn Date: Thu, 25 Dec 2025 21:06:48 +0100 Subject: [PATCH 1/8] feature: Add pattern rotation with Konva Transformer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement comprehensive pattern rotation functionality: - Use Konva Transformer for native rotation UI with visual handles - Apply rotation transformation at upload time to stitch coordinates - Two-layer preview system: original (draggable/rotatable) and uploaded (locked) - Automatic position compensation for center shifts after rotation - PEN encoding/decoding with proper bounds calculation from decoded stitches - Comprehensive unit tests for rotation math and PEN round-trip - Restore original unrotated pattern on delete The rotation is applied by transforming stitch coordinates around the pattern's geometric center, then re-encoding to PEN format. Position adjustments compensate for center shifts caused by PEN encoder rounding to maintain visual alignment. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/components/FileUpload.tsx | 177 ++++++++- src/components/KonvaComponents.tsx | 147 ++++++- src/components/PatternCanvas.tsx | 605 ++++++++++++++++++++--------- src/stores/useMachineStore.ts | 4 + src/stores/usePatternStore.ts | 78 +++- src/utils/rotationUtils.test.ts | 314 +++++++++++++++ src/utils/rotationUtils.ts | 82 ++++ 7 files changed, 1196 insertions(+), 211 deletions(-) create mode 100644 src/utils/rotationUtils.test.ts create mode 100644 src/utils/rotationUtils.ts diff --git a/src/components/FileUpload.tsx b/src/components/FileUpload.tsx index f4ec242..3ad24c4 100644 --- a/src/components/FileUpload.tsx +++ b/src/components/FileUpload.tsx @@ -11,6 +11,12 @@ import { canUploadPattern, getMachineStateCategory, } from "../utils/machineStateHelpers";

charset=UTF-8 Content-Transfer-Encoding: 8bit Extract duplicate code into reusable utilities: - calculatePatternCenter(): Eliminates 6x duplication of center calculations - convertPenStitchesToPesFormat(): Eliminates 3x duplication of stitch conversion - calculateZoomToPoint(): Eliminates 2x duplication of zoom math Reorganize into subfolder: - Created src/components/PatternCanvas/ directory - Moved PatternCanvas.tsx into subfolder - Added index.ts for clean imports - All utilities in patternCanvasHelpers.ts Benefits: - Reduced ~50+ lines of duplicated code - Single source of truth for common operations - Easier to test and maintain - Better code organization 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- .../PatternCanvas/PatternCanvas.tsx | 740 ++++++++++++++++++ src/components/PatternCanvas/index.ts | 1 + .../PatternCanvas/patternCanvasHelpers.ts | 59 ++ 3 files changed, 800 insertions(+) create mode 100644 src/components/PatternCanvas/PatternCanvas.tsx create mode 100644 src/components/PatternCanvas/index.ts create mode 100644 src/components/PatternCanvas/patternCanvasHelpers.ts diff --git a/src/components/PatternCanvas/PatternCanvas.tsx b/src/components/PatternCanvas/PatternCanvas.tsx new file mode 100644 index 0000000..8b0d213 --- /dev/null +++ b/src/components/PatternCanvas/PatternCanvas.tsx @@ -0,0 +1,740 @@ +import { useEffect, useRef, useState, useCallback } from "react";
