Trim Paths Pro

Available under Vector Graphics → Trim Paths Pro. Combines local edge trimming, per-path reveals, whole-input sequencing and overlapping visual groups. Start, End and Origin map independently; Origin shifts the trim with wrapping, and progress can use edge count or distance. Existing trim nodes remain available for older patches.

See Trim Paths Pro usage and vector mapping for examples, output formats, group editing and legacy equivalents. Run python3 tests/trim_paths_pro_regression.py on macOS with compiled sibling OF libraries, or add --core-only for the standalone geometry regressions.

SVG Polyline Loader

Available under Vector Graphics → SVG Polyline Loader. The existing SVG Modulator remains available for older patches.

• Load SVG opens the native file picker in the application's data folder. Cancelling leaves the current file unchanged; selecting the same file reloads it.
• File accepts an absolute path or a path relative to data, and is saved in presets. The SVG is referenced externally, not embedded in the preset.
• Curve Resolution (default 32, range 2–1024) sets the number of segments per Bezier curve. Increasing it improves curved outlines. Straight segments retain their vertices; this is not uniform distance resampling.
• Normalize defaults to on: divide X by the SVG viewport width and Y by its height. Disable it for original viewport coordinates. Coordinates outside the viewport remain outside 0–1, and the Y axis follows SVG (downwards).
• Rotate90º rotates clockwise by 90° per click; four clicks restore the original orientation. Rotation is around (0.5, 0.5) when normalized, or the SVG viewport center otherwise. The viewport stays fixed, so rotating a non-square SVG in original coordinates can put vertices outside its original viewport.
• FlipX mirrors horizontally and FlipY vertically about the same center, after rotation. Separators are never transformed. These settings survive file reloads and sampling changes; flips and the Inspector's Quarter Turns value are saved in presets. Set Quarter Turns to 0 to reset rotation.
• Scale uses 0–1, default 1 (original size); 0 collapses every contour to the canvas center. Scaling is uniform about the same center as rotation.
• Rotate uses −1…1 for −90°…90°, default 0. Positive angles turn clockwise. This angle adds to the rotation applied with Rotate90º.
• MoveX / MoveY use −1…1, default 0. Values are fractions of the full canvas width/height; positive moves right/down. With Normalize off, those offsets are multiplied by the SVG width/height. Translation is applied after rotation, flipping and scaling. Outputs are not clamped to the canvas.
• All transform controls persist in presets and are reapplied after file reloads and sampling changes.
• Vertex_Y, then Vertex_X, contain equally sized float vectors. Y is published before X, matching SVG Modulator, Points Resampler and Shape Transform. Each nonempty contour ends in -1 in both vectors, including the last contour. Closed contours repeat their first vertex before that separator. The -1 value is reserved by this coordinate protocol.

The loader uses the existing ofxSvg dependency and its supported SVG subset. It preserves open subpaths and fill-only outlines, flattens Beziers, handles transforms and viewBox-only exports, and keeps the parser's path order. Text, embedded images, clipping, CSS and other advanced SVG features are limited by ofxSvg; convert text to outlines when exporting. Color output is not included. Invalid or missing files clear the coordinates and show an error on the node.

Run python3 tests/svg_polyline_loader_regression.py on macOS with compiled sibling openFrameworks libraries. It syntax-checks the addon and runs real SVG parsing/geometry tests with ASan/UBSan; node registration and the native dialog are simulated in the runtime fixture. The native UI still needs a host-app check.
