Tokimu Paint¶

Tokimu Paint is an experimental consumer corpus for an ordinary raster editing workflow. It pressures a narrow composition boundary: Tokimu-owned decoded pixels, edit commands, history, preview bytes, and PNG export meet browser input, Canvas presentation, and download mechanisms without changing ownership.

What This Proves¶

browser file / pointer / keyboard
                ↓
         TypeScript adapter
                ↓
        Rust/WASM PaintSession
                ↓
editable raster document + history
                ↓
      copied preview bytes to Canvas

The browser does not decode source images, own the editable buffer, or produce the exported image. Canvas is a presentation target only.

Experimental consumer evidence / on demand

Raster workbench

Activate a bounded Rust/WASM editing session. The current proof supports a blank document or admitted PNG, JPEG, and BMP input; pencil, eraser, exact-match fill, sampling, undo, redo, and deterministic PNG export.

This is consumer evidence, not a general editor or a browser-native image fallback. The page remains useful if the interactive payload is unavailable.

Idle No editable document session loaded

Limits¶

The editable document is an application-local, top-down RGBA8 profile.
PNG export is deterministic; original source encoding is not preserved.
The current raster providers admit a bounded PNG, baseline JPEG, and BMP profile rather than broad image-format compatibility.
Browser interaction is not a claim that TypeScript or Canvas owns image semantics.
