だから私はこれを機能させる方法を見つけました(小さなAngularコード「$scope.$watch...」と混ぜて)私は今、フォントのデコードに関して他の問題を抱えています。しかし、ここに他の誰かを助けるかもしれない解決策があります。

scale: SCALE,
defaultViewport: page.getViewport(SCALE),

pdfPageView.setPdfPage(page);
return pdfPageView.draw();
}

var pageLoadPromises = [];
for (var num = 1; num <= pdfDoc.numPages; num++) {
pageLoadPromises.push(pdfDoc.getPage(num).then(renderPage));
}
return $q.all(pageLoadPromises);
}
PDFJS.disableWorker = true;
return PDFJS.getDocument(url)
