Capture Area
When you press the hotkey, Xenocept captures a screenshot of the monitor under your cursor — and only that monitor. The overlay opens on top of that monitor’s freeze-frame.
That’s it for the capture step. There is no multi-monitor coordination and no persistent capture rectangle that selects which monitors to freeze.
The Session-Area Tool
The closest thing to “a saved capture region” inside the overlay is the Session-Area tool (Area in the radial menu — ).
When you draw a session-area rectangle on the overlay, you’re defining a crop region for the final submitted screenshot. Everything inside that rectangle is what gets saved to screenshot.png on Submit. The rest of the captured monitor’s pixels are discarded for the submitted artifact (but screenshot-clean.png, if generated, may include the full background — see Snapshot).
The session-area:
- Is a single rectangle per overlay session
- Has a minimum size of 20×20 pixels
- Is drawn the same way as any other rectangle (click-drag), and resized/moved the same way
- Resets along with the rest of the canvas state on the next hotkey press
What’s Captured vs What’s Submitted
Two different things:
| Stage | What it is |
|---|---|
| Capture (on hotkey) | Full screenshot of the monitor under the cursor, used as the overlay background. |
| Submit | The session-area’s crop becomes screenshot.png. Each Note captures a focus-{i}.png from its focus area. The screenshot-clean.png is the background-only image (no markup) if the frontend generated one. |
Notes are independent of the session-area: a Note can be made anywhere on the overlay, even outside the session-area rectangle.
