How to use the vott-ct/lib/js/CanvasTools/Core/RegionData.RegionData function in vott-ct

public static createTestRegionData() {
        const origin = {
            x: randomIntInRange(0, 1024),
            y: randomIntInRange(0, 768),
        };
        const size = {
            width: randomIntInRange(1, 100),
            height: randomIntInRange(1, 100),
        };

        return new RegionData(origin.x, origin.y, size.width, size.height,
            [
                new Point2D(origin.x, origin.y), // Top left
                new Point2D(origin.x + size.width, origin.y), // Top Right
                new Point2D(origin.x, origin.y + size.height), // Bottom Left
                new Point2D(origin.x + size.width, origin.y + size.height), // Bottom Right
            ],
            RegionDataType.Rect);
    }
