手动调用PDFJS函数。在PDFView.open渲染后调用什么函数

Question

在文档中找不到接下来要做的事情。

呼叫：

PDFView.open('/MyPDFs/Pdf1.pdf', 'auto', null) 

我能看到空白页，装载机，也是文件得到我的PDF页面的数量。

唯一缺少的就是渲染。 有人知道我应该接下来打电话吗？ 感谢

$(document).ready(function() { 
    PDFView.initialize(); 

    var params = PDFView.parseQueryString(document.location.search.substring(1)); 

    //#if !(FIREFOX || MOZCENTRAL) 
    var file = params.file || DEFAULT_URL;

    // Special debugging flags in the hash section of the URL. 
    var hash = document.location.hash.substring(1); 
    var hashParams = PDFView.parseQueryString(hash); 

    if ('disableWorker' in hashParams) 
     PDFJS.disableWorker = (hashParams['disableWorker'] === 'true');

    } 

    if (PDFView.supportsIntegratedFind) { 
     document.querySelector('#viewFind').classList.add('hidden'); 
    } 

    // Listen for warnings to trigger the fallback UI. Errors should be caught 
    // and call PDFView.error() so we don't need to listen for those.

      PDFView.renderHighestPriority();

    document.getElementById('viewThumbnail').addEventListener('click',

     }); 

    document.getElementById('pageNumber').addEventListener('change', 
     function() { 
      PDFView.page = this.value; 
     }); 

    document.getElementById('scaleSelect').addEventListener('change',

    document.getElementById('last_page').addEventListener('click', 
     function() { 
      PDFView.page = PDFView.pdfDocument.numPages; 
     }); 

    document.getElementById('page_rotate_ccw').addEventListener('click', 
     function() { 
      PDFView.rotatePages(-90); 
     }); 

    document.getElementById('page_rotate_cw').addEventListener('click', 
     function() { 
      PDFView.rotatePages(90); 
     }); 

    //#if (FIREFOX || MOZCENTRAL) 
    //if (FirefoxCom.requestSync('getLoadingType') == 'passive') { 
    // PDFView.setTitleUsingUrl(file); 
    // PDFView.initPassiveLoading(); 
    // return; 
    //} 
    //#endif 

    //#if !B2G 

    PDFView.open(file, 0); 
    //#endif 
}); 

系统必须首先初始化PDFView.open调用之前！谢谢

在viewer.js中，我在文档下载后添加了对updateViewarea（）的调用。

... PDFJS.getDocument(parameters).then(
    function getDocumentCallback(pdfDocument) { 
    self.load(pdfDocument, scale); 
    self.loading = false; 
    updateViewarea(); 
    }, ...
