    <div>
      <h1>Pixels Image React Component</h1>
      <PixelsImage
        src="path/to/your/image.jpg"
        saturation={0.5} // -1 to 1 (-100% to 100%)
        brightness={1} // -1 to 1 (-100% to 100%)
        contrast={-0.2} // -1 to 1 (-100% to 100%)
      />
    </div>
  );
}

export default App;

Flip Image

      <h1>Pixels Image React Component</h1>
      <PixelsImage
        src="path/to/your/image.jpg"

        brightness={0.2}
        onFilter={async (exportObject) => {
            await exportObject.getBlob() // for large images
            exportObject.getDataURL() // for small images
            exportObject.getCanvas() // get canvas object
            await exportObject.getImageFromDataURL() // same as getDataURL but as a <img> element
            await exportObject.getImageFromBlob() // same as getBlob but as a <img> element
