  # Demo Filters 012

  Filter parameters: matrix, matrix5

- §

  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 filters

      const matrix3 = scrawl.makeFilter({

          name: 'matrix3',
          method: 'matrix',

          weights: [0, 0, 0, 0, 1, 0, 0, 0, 0],
      });

      const matrix5 = scrawl.makeFilter({

          name: 'matrix5',
          method: 'matrix5',

          weights: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
      });

- §

  Create the target entity

      const target = scrawl.makePicture({

          name: 'base-piccy',

          asset: 'iris',

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

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

          method: 'fill',

          filters: ['matrix3'],
      });

- §

  #### 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 `    matrix3 weights array: ${matrix3.weights}\n    matrix5 weights array: ${matrix5.weights}    \n    Opacity: ${opacity.value}`;
      });

- §

  Create the Display cycle animation

      scrawl.makeRender({

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