  # Demo Filters 023

  Filter parameters: randomNoise

- §

  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: 'my-filter',
          method: 'randomNoise',

          width: 6,
          height: 6,
          level: 0.5,
      });

- §

  Create the target entity

      const piccy = scrawl.makePicture({

          name: 'base-piccy',

          asset: 'iris',

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

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

          method: 'fill',

          filters: ['my-filter'],
      });

- §

  #### 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 `    Width: ${width.value}, Height: ${height.value}\n    Level: ${level.value}\n    Opacity - ${opacity.value}`;
      });

- §

  Create the Display cycle animation

      scrawl.makeRender({

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

- §

  #### User interaction

      scrawl.makeUpdater({

          event: ['input', 'change'],
          origin: '.controlItem',

          target: myFilter,

          useNativeListener: true,
          preventDefault: true,

          updates: {

              width: ['width', 'round'],
              height: ['height', 'round'],
              opacity: ['opacity', 'float'],
              level: ['level', 'float'],
              noWrap: ['noWrap', 'boolean'],
              includeRed: ['includeRed', 'boolean'],
              includeGreen: ['includeGreen', 'boolean'],
              includeBlue: ['includeBlue', 'boolean'],
              includeAlpha: ['includeAlpha', 'boolean'],
              noiseType: ['noiseType', 'raw'],
          },
      });

  Setup form

      const width = document.querySelector('#width'),
          height = document.querySelector('#height'),
          level = document.querySelector('#level'),
          opacity = document.querySelector('#opacity');

- §
