@remotedraw/geometry

Normalized stroke geometry, shape assist, hit testing, transforms, and export helpers for RemoteDraw drawings. Framework-free and has no dependency on @remotedraw/client, @remotedraw/protocol, or any UI library — pure geometry math over RemoteDraw's 0..1 normalized stroke coordinates.

What it provides:

• buildNormalizedStroke / recognizeStroke / snapNormalizedStrokeEndpoints — shape assist: turning raw pointer input into normalized strokes and recognizing lines, rectangles, ellipses, and arrows.
• hitTestDrawing / pickDrawings / pickTopmostDrawing — hit testing for selecting drawings on a board.
• composeDrawingTransforms / transformBoardPoint / transformFromPivotGesture — 2D affine transforms for moving, scaling, and rotating drawings.
• drawingsToSvg / drawingsToSvgPath / drawingsToJson — export helpers for rendering or serializing a set of drawings.

import { hitTestDrawing, pickTopmostDrawing } from "@remotedraw/geometry";

const hit = pickTopmostDrawing(drawings, point, { strokeWidth: 6 });

Most integrations consume this indirectly through @remotedraw/react, which re-exports the pieces it uses for selection and rendering. Depend on it directly for custom board UIs or server-side geometry (export, hit testing) outside a @remotedraw/react app.
