Quick usage and examples

    // initialize the generator
    var generator = tgen.init(256, 256);


    // --- texture 1 --------------------------------------------------------------

    var canvas1 = generator
            .do('waves')
            .toCanvas();

    // set img src, and width height
    $('#img1').attr('src', canvas1.toDataURL("image/png")).css({width: canvas1.width, height: canvas1.height});


    // --- texture 2 --------------------------------------------------------------

    var canvas2 = generator
            .do('fill')
            .do('waves', {blend: 'difference'})
            .do('waves', {blend: 'difference'})
            .do('contrast', {"adjust": 50})
            .toCanvas();

    // set img src, and width height
    $('#img2').attr('src', canvas2.toDataURL("image/png")).css({width: canvas2.width, height: canvas2.height});


    // --- texture 3 --------------------------------------------------------------

    var texture3 = generator
            .clear() // remove previous layers
            .do('fill')
            .do('clouds', {blend: 'difference'})
            .do('spheres', {blend: 'lineardodge', 'dynamic': true})
            .do('vibrance', {"adjust": 50});

    var canvas3 = texture3.toCanvas();

    // set img src, and width height
    $('#img3').attr('src', canvas3.toDataURL("image/png")).css({width: canvas3.width, height: canvas3.height});


    // --- texture 4 --------------------------------------------------------------

    // get the generated params of texture3
    var params = texture3.params();

    // get number of layers
    var layers = params.items.length;

    // change the color of clouds
    params.items[layers - 3][2].rgba = [255, 50, 10, 0.85];

    // change the blending method
    params.items[layers - 2][2].blend = 'overlay';

    // generate new texture with modified params of texture3
    var canvas4 = generator.render(params).toCanvas();

    // set img src, and width height
    $('#img4').attr('src', canvas4.toDataURL("image/png")).css({width: canvas4.width, height: canvas4.height});


    // --- texture 5 --------------------------------------------------------------

    $('#img6').attr('src', canvas6.toDataURL("image/png")).css({width: canvas6.width, height: canvas6.height});


    // --- available effects -------------------------------------------------------
