# Control protocol
> **Last updated:** 2026-10-23 · **Change:** symbol library panels (`window.symbolLibrary`, `window.symbolLibrary.other`, `ui.saveSymbolLibrary`); previously: synthetic input budgets (#1709); bounded transport waits (#1726).
> **Last updated:** 2026-10-24 · **Change:** `ui.screenshot`'s 64 MiB inline-PNG cap and its path-plus-data downgrade; previously: symbol library panels (`window.symbolLibrary`, `window.symbolLibrary.other`, `ui.saveSymbolLibrary`); synthetic input budgets (#1709); bounded transport waits (#1726).
`vectorcraft --control <port>` listens on `127.0.0.1:<port>` (loopback only). The port must be a number
from 1 to 65535 (`--control=<port>` works too), given once; otherwise the app prints an error and exits

Over the canvas the wheel scrolls and Cmd- or Alt-wheel (Option on the Mac) zooms about the pointer; with the `zoomWithMouseWheel` preference the wheel and Alt-wheel zoom about the pointer, Shift-wheel scrolls up and down and Cmd-wheel (Ctrl on Windows and Linux) sideways. Over a focused numeric field (click it first) each notch steps its value as Up/Down do (Shift: ten, Cmd/Ctrl: a tenth) and the panel stays put; over anything else in a panel the wheel scrolls it |

| `ui.screenshot` | `{path?, data?}` | capture the window (PNG), written to `path`; `data: true` sends it back as `pngBase64` too. The inline PNG is capped at 64 MiB: with a `path` the file is still written and `pngBase64` is omitted when the image is larger, while a path-less `data: true` request fails if either the raw RGBA image or the encoded PNG exceeds the cap.
