我可以直接添加注释:http://annotorious.github.io/demos/openseadragon-preview.html

用户添加注释后,我存储在我的数据库中.当用户刷新页面时,我使用ajax call(H_AnnotationHandler.php)从数据库加载已保存的数据.返回数据是真的,但我无法在jpeg2000图像上使用绘制注释anno.addAnnotation,我该如何绘制它?

参考:添加注释API.

您在方法中缺少src属性anno.addAnnotation,问题是我真的不知道那里应该放什么值,文档中没有任何内容,我在互联网上唯一能找到的就是这个插件:

https://github.com/dgutman/OpenSeadragon-Plugins/tree/master/annotationState_Code

你可以尝试这样做。

我实际上设法以编程方式在演示页面上附加事件,那里的开放海龙模块注册为 a dzi://openseadragon/something,知道这一点您可以调用该函数

anno.addAnnotation({
    src : 'dzi://openseadragon/something',
    text : 'My annotation',
    shapes : [{
        type : 'rect',
        geometry : { x : 0.8, y: 0.8, width : 0.2, height: 0.2 }
    }]
});

从控制台(或在 ajax-success 循环中的代码中),它将被添加到图像中。然而,命名方法相当......好吧,我在源代码中发现了这个:

annotorious.mediatypes.openseadragon.OpenSeadragonModule.prototype.getItemURL = function(item) {
  // TODO implement something decent!
  return 'dzi://openseadragon/something';
}

所以请放心,这种情况将来可能会改变。
