    maxScale?: number;
    minScale?: number;
    mode?: "fill" | "contain" | "stretch";
    padding?: number;
}

Properties

maxScale?: number

Override the kit's system max scale. Defaults to the kit-wide max zoom used by computeWheelAction / useZoom (currently 10).

minScale?: number

Override the kit's system min scale. Defaults to the kit-wide min zoom used by computeWheelAction / useZoom (currently 0.1).

mode?: "fill" | "contain" | "stretch"

Fit mode:

'contain' (default): uniform scale = min(availW/w, availH/h). Bounds fit entirely; one axis has letterboxing.
'fill': uniform scale = max(...). Bounds overflow viewport on one axis.
'stretch': per-axis scale. Bounds match viewport exactly; scale is non-uniform.

padding?: number

Inset (in CSS px) around the bounds. Default 16.
