Images disappeared in PDF made by Pechkin.Synchronized

924 Views Asked by Oh Chunseok At 10 December 2015 at 06:58

I wrote some code for making PDF from HTML with pechkin and pechkin.synchronized.

It will work very well at first time.

Since second time, images are disappeared in pdf. Other [html to pdf]s are too. First pdf is right. Other pdfs are not. At the first time in server, it will work.

Maybe because pechkin will not unload in memory. I think.

I need help.

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);
