  # Demo Filters 002

  Filter parameters: red, green, blue, cyan, magenta, yellow, notred, notgreen, notblue, grayscale, sepia, invert

- §

  Run code

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

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

- §

  #### Scene setup

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

      scrawl.importDomImage('.flowers');

- §

  Create the filters

      scrawl.makeFilter({
          name: 'red',
          method: 'red',
      }).clone({
          name: 'green',
          method: 'green',
      }).clone({
          name: 'blue',
          method: 'blue',
      }).clone({

  #### 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 `    Opacity: ${opacity.value}`;
      });

- §

  Create the Display cycle animation

      scrawl.makeRender({

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

  #### User interaction

      const myFilters = [

          filter.green,
          filter.blue,
          filter.cyan,

          myPictures.forEach(p => p.set({ memoizeFilterOutput: val }));

      }, '#memoizeFilterOutput');

- §

  Setup form @ts-expect-error

      document.querySelector('#memoizeFilterOutput').options.selectedIndex = 0;
      const opacity = document.querySelector('#opacity');

- §

  @ts-expect-error

      opacity.value = 1;

  #### Drag-and-Drop image loading functionality

      addImageDragAndDrop(canvas, '#my-image-store', myPictures);

- §

  #### Development and testing

      console.log(scrawl.library);
