Deftrial Live Board — Public Test Help
This board is a cPanel-friendly collaborative canvas. It uses room codes, fixed 1920×1080 coordinates, layers, media imports, project snapshots, and mobile/PC controls.
Quick start
- Open
index.html. - Enter your name.
- Create a room or enter a room code and join.
- Use Editor link for collaborators, Viewer link for read-only guests.
- Save a project snapshot before leaving.
Mobile gestures
Use the bottom toolbar for core tools. Open Menu for layers, media, color, and project controls. One finger draws in drawing tools. Hand pans. Pinch zooms.
Layers
Each player gets a layer. Host can manage all layers. Normal editors should use their own layer unless shared layers are enabled.
Images
Import PNG, JPG, or WebP as an object, background, or reference picture-in-picture. Large images are compressed before upload.
Projects
Use Save to create a snapshot, Load to continue, JSON export for backup, and Import JSON to restore a downloaded project.
Troubleshooting
- If mobile only shows a blank canvas, refresh once and use the top quickbar or bottom Menu.
- If drawing feels offset, test input-test.html.
- If rooms do not save, run install-check.php and admin-check.php.
- If the board gets slow, run cleanup in dry-run first, then remove stale rooms.
