  # Demo Filters 008

  Filter parameters: tint

- §

  Run code

      import * as scrawl from '../source/scrawl.js';

      import { reportSpeed, addImageDragAndDrop } from './utilities.js';

- §

  #### Scene setup

      const canvas = scrawl.library.canvas.mycanvas;

      scrawl.importDomImage('.flowers');

- §

  Create the filter

      const myFilter = scrawl.makeFilter({

          name: 'tint',
          method: 'tint',

- §

  These values create the sepia tint

          redInRed: 0.393,
          redInGreen: 0.349,
          redInBlue: 0.272,
          greenInRed: 0.769,
          greenInGreen: 0.686,
          greenInBlue: 0.534,
          blueInRed: 0.189,
          blueInGreen: 0.168,
          blueInBlue: 0.131,
      });

      const colorFactory = scrawl.makeColor({
          name: 'my-color-factory',
      });

- §

  Create the target entity

      const piccy = scrawl.makePicture({

          name: 'base-piccy',

          asset: 'iris',

          width: '100%',
          height: '100%',

          copyWidth: '100%',
          copyHeight: '100%',

          method: 'fill',

          filters: ['tint'],
      });

- §

  #### Scene animation

  Function to display frames-per-second data, and other information relevant to the demo

      const report = reportSpeed('#reportmessage', function () {

- §

  @ts-expect-error

          return `    In Red - red: ${redInRed.value} green: ${greenInRed.value} blue: ${blueInRed.value} → ${redColor.value}\n    In Green - red: ${redInGreen.value} green: ${greenInGreen.value} blue: ${blueInGreen.value} → ${greenColor.value}\n    In Blue -  red: ${redInBlue.value} green: ${greenInBlue.value} blue: ${blueInBlue.value} → ${blueColor.value}\n    Opacity: ${opacity.value}`;
      });

- §

  Create the Display cycle animation

      scrawl.makeRender({

          name: "demo-animation",
          target: canvas,
          afterShow: report,
      });

                  val = e.target.value;

              let [r, g, b] = colorFactory.extractRGBfromColor(val);

              r /= 255;
              g /= 255;
              b /= 255;

              if ('redColor' === target) {

                  myFilter.set({ redColor: val });
