Pentool v0.1.0

An agent-friendly vector editor in one Rust binary. Draw with CLI commands,
export without a browser, and edit the same layered artwork visually.

Included

  • Canvas creation, backgrounds, and editable .pen JSON documents.
  • Layer creation, ordering, visibility, locks, and whole-layer transforms.
  • SVG-compatible strokes, fills, Bézier curves, and arcs.
  • Shared Rust geometry for translation, rotation, scaling, anchor and handle
    editing, curve splitting, bounds, and hit testing.
  • Native PNG and SVG export; no Node.js, browser, or server required for CLI work.
  • Embedded browser editor, JSON rendering/geometry API, and explicit shared-file
    save/reload with stale-save detection.
  • Editable eye and XYSKID examples and their exported previews.

Quick start

Download and extract the archive for your operating system, then run:

pentool serve examples/eye.pen

Open http://127.0.0.1:4711. For browser-free output:

pentool export examples/eye.pen eye.png --scale 2
pentool layer-geometry examples/xyskid.pen --layer symbol translate 40 20

On Windows the executable is pentool.exe; macOS/Linux users can run ./pentool
from the extracted folder or add it to PATH.

Early release limitations

This is a geometry foundation, not a complete replacement for Figma or Photoshop.
Shape boolean operations, automatic snapping/alignment, complete undo history,
and a native desktop window are not included. Browser synchronization is explicit.
Transforms preserve stroke width, and SVG arcs become Bézier approximations when
edited. Binaries are not code-signed.
