Interface ViewportZoomOptions`Experimental`

interface ViewportZoomOptions {
    max?: number;
    min?: number;
    wheel?: "plain" | "mod";
}

Properties

max?: number

Upper clamp on the resulting view scale, forwarded to zoomAt. Default 8.

min?: number

Lower clamp on the resulting view scale, forwarded to zoomAt. Default 0.1.

wheel?: "plain" | "mod"

Which wheel gesture triggers zoom.

'mod' (default): Cmd/Ctrl+wheel — coexists with plain-wheel pan (viewport.wheelPan) and Mac trackpad pinch (ctrl+wheel).
'plain': bare wheel, no modifier. Pair with viewport.pan: false, since plain wheel otherwise drives pan and the two would compete.
