HTML5 Canvas画板画图工具 可定义笔刷和画布

这是一款基于HTML5 Canvas的网络画板应用，简化版的，可以自己在上面扩展。

核心jQuery代码：

function prepareCanvas()
{
    // Create the canvas (Neccessary for IE because it doesn't know what a canvas element is)
    var canvasDiv = document.getElementById('canvasDiv');
    canvas = document.createElement('canvas');
    canvas.setAttribute('width', canvasWidth);
    canvas.setAttribute('height', canvasHeight);
    canvas.setAttribute('id', 'canvas');
    canvasDiv.appendChild(canvas);
    if(typeof G_vmlCanvasManager != 'undefined') {
        canvas = G_vmlCanvasManager.initElement(canvas);
    }
    context = canvas.getContext("2d"); // Grab the 2d canvas context
    // Note: The above code is a workaround for IE 8 and lower. Otherwise we could have used:
    //     context = document.getElementById('canvas').getContext("2d");

    // Load images
    // -----------
    crayonImage.onload = function() { resourceLoaded();
    };
    crayonImage.src = "images/crayon-outline.png";
    //context.drawImage(crayonImage, 0, 0, 100, 100);

    markerImage.onload = function() { resourceLoaded();
    };
    markerImage.src = "images/marker-outline.png";

    eraserImage.onload = function() { resourceLoaded();
    };
    eraserImage.src = "images/eraser-outline.png";    

    crayonBackgroundImage.onload = function() { resourceLoaded();
    };
    crayonBackgroundImage.src = "images/crayon-background.png";

    markerBackgroundImage.onload = function() { resourceLoaded();
    };
    markerBackgroundImage.src = "images/marker-background.png";

    eraserBackgroundImage.onload = function() { resourceLoaded();
    };
    eraserBackgroundImage.src = "images/eraser-background.png";

    crayonTextureImage.onload = function() { resourceLoaded();
    };
    crayonTextureImage.src = "images/crayon-texture.png";

    outlineImage.onload = function() { resourceLoaded();
    };
    outlineImage.src = "images/watermelon-duck-outline.png";

    // Add mouse events
    // ----------------
    $('#canvas').mousedown(function(e)
    {
        // Mouse down location
        var mouseX = e.pageX - this.offsetLeft;
