androidx5webview,截长图有不模糊的写法吗,现在截图出来都很模糊.有什么解决方法吗?

    int width = webView.getContentWidth();

    int height = webView.getContentHeight();

    Bitmap x5bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);

    Canvas x5canvas = new Canvas(x5bitmap);

    //这个截图出来的很模糊

    webView.getX5WebViewExtension().snapshotWholePage(x5canvas, false, false);
