Question

我写了一些代码，用于使用pechkin和pechkin.synchronized从HTML制作PDF。

第一次会很好用。

自第二次以来，图像在pdf中消失。其他[html到pdf]也是。首先是pdf是对的。其他pdf不是。在服务器中第一次使用它。

也许是因为pechkin不会在内存中卸载。我想。

我需要帮助。

System.IO.File.WriteAllText(textfilepath, html);
GlobalConfig gc = new GlobalConfig();

ObjectConfig oc = new ObjectConfig()
    .SetLoadImages(true)
    .SetZoomFactor(1.0)
    .SetPrintBackground(true)
    .SetScreenMediaType(true)
    .SetCreateExternalLinks(true)
    .SetAllowLocalContent(true)
    .SetPageUri(url);

IPechkin pechkin = new Pechkin.Synchronized.SynchronizedPechkin(gc);

pdf = pechkin.Convert(oc);
