  # Demo Filters 003

  Filter parameters: brightness, saturation

- §

  Run code

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

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

- §

  #### Scene setup

      const canvas = scrawl.library.canvas.mycanvas,
          filter = scrawl.library.filter,
          entity = scrawl.library.entity;

      scrawl.importDomImage('.flowers');

- §

  Create the filters

      scrawl.makeFilter({
          name: 'brightness',
          method: 'brightness',
          level: 1,
      }).clone({
          name: 'saturation',
          method: 'saturation',
      });

      scrawl.makeFilter({
          name: 'advancedbrightness',
          actions: [{
              action: 'modulate-channels',
              red: 1,
              green: 1,
              blue: 1,
              alpha: 1,
          }],
      }).clone({
          name: 'advancedsaturation',
          actions: [{
              action: 'modulate-channels',
              red: 1,
              green: 1,
              blue: 1,
              alpha: 1,
              saturation: true,
          }],
      });

      const simpleFilters = [filter.brightness, filter.saturation];
      const advancedFilters = [filter.advancedbrightness, filter.advancedsaturation];

- §

  Create the target entitys

      scrawl.makePicture({

          name: 'brightness-picture',

          asset: 'iris',

          dimensions: [200, 200],

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

          method: 'fill',

          filters: ['brightness'],

      }).clone({

          name: 'saturation-picture',
          startX: 200,
          filters: ['saturation'],

      }).clone({

          startY: 200,
          filters: ['advancedsaturation'],

      }).clone({

          name: 'advanced-brightness-picture',
          startX: 0,
          filters: ['advancedbrightness'],
      });

      scrawl.makePhrase({

          name: 'brightness-label',
          text: 'Brightness',

          font: '30px sans-serif',
          width: '45%',

          fillStyle: 'white',
          lineWidth: 4,

          method: 'drawThenFill',

          pivot: 'brightness-picture',
          lockTo: 'pivot',
          offset: [5, 5],

      }).clone({

      });

- §

  Create the Display cycle animation

      scrawl.makeRender({
