Pixastic ColorAdjust Type Error未定义

标签: javascript jquery html pixastic

我真的希望有人能够提供帮助......我有两倍,三倍和四倍检查Pixastic库正在加载。

这是我的HTML代码:

<head>标记中:

<script src="pathto.../pixastic.js"></script>
<script src="pathto.../pixastic.effects.js"></script>
<script src="pathto.../pixastic.worker.js"></script>

<body>标记中:

<div id="pattern-div" class="">
<div id="preview-background-print"><img id="preview-image" src="/image.png"/></div>
</div>

这是jQuery。我省略了计算RGB偏移的公式,因为它们看起来并不相关。但如果他们是,请告诉我。 :)

$('#preview-image').pixastic('coloradjust',{
    red : pixadjustR,
    green : pixadjustG,
    blue : pixadjustB
});

这是我得到的错误:

TypeError: $('#preview-image').pixastic is not a function. (In '$('#preview-image').pixastic('coloradjust',{
        red : pixadjustR,
        green : pixadjustG,
        blue : pixadjustB
    })', '$('#preview-image').pixastic' is undefined)`

(我也尝试过Pixastic.process(document.getElementById("preview-image"), "coloradjust"...并获得Pixastic.process is not a function等等。

答案 0 :(得分:1)

您是否包含pixastic jquery plugin

如果你想在没有jquery插件的情况下这样做,这与他们在demo中的表现类似:

function pixastic(img, method, options){
    // Copy image to canvas
    var canvas = document.createElement('canvas');
    canvas.width = img.width;
    canvas.height = img.height;
    var ctx = canvas.getContext("2d");
    ctx.drawImage(img, 0, 0);
    // Create Pixastic object and execute filter.
    // The second parameter is the path to the folder containing the worker script 
    var P = new Pixastic(ctx);
    P[method](options).done(function(){
        // Copy the data back to the image as dataURI
        img.src = canvas.toDataURL();
    });
}
pixastic($('img')[0], "coloradjust", {
  red : pixadjustR,
  green : pixadjustG,
  blue : pixadjustB
})
