The canvas

Moving and resizing

Drag a source body to move it, and drag a corner or edge handle to resize. Hold the modifier key to preserve the aspect ratio while resizing.

Snapping

While dragging, sources snap to the canvas edges, the canvas centre, and the edges of other sources. Guides appear when a snap is available. Snapping keeps layouts tidy without pixel-hunting.

Zoom and pan

• Scroll to zoom around the pointer.
• Drag the background to pan when zoomed in.
• Use the View menu to fit the canvas to the window or reset the zoom.

Borders and labels

Each source can show a border and a label. Borders make adjacent feeds readable, and labels name the source on screen. Both are toggled per source in its settings.

Flips

Horizontal and vertical flips are available per source, for mirroring a camera or correcting an inverted feed.
