Controlling the Photo Booth
Scripts and external applications can control the photo booth by sending key presses (see Keyboard Shortcuts) or by sending WM_COPYDATA Windows messages to the photo booth window.
WM_COPYDATA Messages
| Data value | Description |
|---|---|
| 100 | Pathname of a photo — signals that post-processing of that photo has completed (equivalent to Ctrl+Z in the droplet.ahk script). |
| 200 | A URL containing commands and/or strings — processes QR code-style URLs to control the booth, read user info, and send emails. See QR Codes and Contactless. |
| 300 | Text of a touchscreen command — runs any defined touchscreen action. Matching ignores case, spaces, and punctuation. |
| 301 | Text of a touchscreen command — same as 300, but the action does not need to be defined in the touchscreen editor. Useful for payment-accepted signals from external payment systems. |
Example: Data=300 command matching
The following strings all match a touchscreen action named Select photobooth+start:
