Advanced Usage

The component works well with gesture libraries like @use-gesture/react for handling zoom and pan interactions:

import { useGesture } from "@use-gesture/react";

function AdvancedExample() {
  const [offset, setOffset] = React.useState({ x: 0, y: 0 });
  const [zoom, setZoom] = React.useState(1);

  useGesture(
    {
      onWheel: ({ delta, ctrlKey, event }) => {
        event.preventDefault();
        if (ctrlKey) {
          setZoom((prev) => prev - delta[1] * 0.01);
        } else {
          setOffset((prev) => ({
            x: prev.x - delta[0],
            y: prev.y - delta[1],
          }));
        }
      },
    },
    {
      wheel: {
        eventOptions: {
          passive: false,
        },
      },
      target: ref,
    }
  );

  return (
    <PixelGrid
      width={window.innerWidth}
      height={window.innerHeight}
      transform={[
        [zoom, 0, offset.x],
        [0, zoom, offset.y],
      ]}
    />
  );
}
