How to reset the filters

[tufail]

Hi,
I like to reset the filters on button click. I am adding below filters code on viewer open

viewer.setFilterOptions({
  filters: [{
      items: viewer.world.getItemAt(0),
      processors: function(context, callback) {
	 Caman(context.canvas, function() {
		this.channels({
		   red: 255,
		   green: 140,
		   blue: 0
	        });
		this.render(callback);
	 });
      }
    },
    {
      items: viewer.world.getItemAt(1), 
      processors: function(context, callback) {
        Caman(context.canvas, function() {
          this.channels({
            red: 0,
            green: 0,
            blue: 60
          });
          this.render(callback);
        });
      }
    }
  ],
  loadMode: 'sync'
});

I have the same question. I hope somebody addresses this issue at some point. The coding style in their current demo implementation does not make it readily apparent what they are doing.

demo.js shows how they set up the interface. But the handlers I think are all in the build demo-bundle.js. Everything's all smooshed together in string evals.

It looks like there's an un-smooshed version in branch nist-pages. But the branch hasn't been updated, so keep in mind things like COLORMAP aren't there.
