ABCpdf doesn't render images in an web application under IIS6

Asked 22/6, 2009 at 16:23 Answered 13/10, 2011 at 13:14

I'm trying to render a web page that contains images into a pdf document using ABCpdf. This is done from a web application.

When I run the application on my development machine in IIS5, everything is fine. When I deploy the application on IIS6, the images don't appear in the pdf.

To reproduce the problem, I made a simple web application to render a pdf file from a simple web page and I found out that the images which are not local are the ones that don't appear in the pdf.

The relevant code that interacts with ABCpdf is:

Doc theDoc = new Doc();
theDoc.Rect.Inset(18, 18);
theDoc.HtmlOptions.PageCacheEnabled = false;
theDoc.HtmlOptions.PageCacheClear();
theDoc.HtmlOptions.UseNoCache = true;
theDoc.HtmlOptions.Timeout = 60000;

int theID = theDoc.AddImageUrl(theUrl);

while (true)
{
  if (!theDoc.Chainable(theID)) break;
  theDoc.Page = theDoc.AddPage();
  theID = theDoc.AddImageToChain(theID);
}

for (int i = 1; i <= theDoc.PageCount; i++)
{
  theDoc.PageNumber = i;
  theDoc.Flatten();
}

theDoc.Save(location);
theDoc.Clear();

The html page that I'm using for test is this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head><title>Test page</title></head>

<body>
<p>This is a local image</p>
<img src="http://myserver/test/images/testimage.gif" />

<p>This is a remote image</p>
<img src="http://l.yimg.com/a/i/ww/beta/y3.gif" />

</body>
</html>

So I'm trying to render the page at this url: http://myserver/test/testpage.html (the code above) into a pdf.

In IIS6, the second image (that is not local for the server) doesn't appear in the pdf.

It seems to be a problem with access rights, but I couldn't figure it out.

Thank you.

have you find any solution to your problem ? – Predisposition 20/4, 2010 at 19:17

Nope. The project was dropped anyway ... – Continuate 16/5, 2011 at 15:23

I know this is a little late, but hopefully will help someone else!

Just been experiencing a very similar problem (which is how I landed at this page..). The version of IIS was the same, but it was being run on a different server. Looks like the problem was more generation of the PDF before the image has finished downloading.

I got in touch with WebSuperGoo. The said under the hood it uses MSHTML (good chance that's the difference in your environments) and a couple of suggestions were to try:

theDoc.SetInfo(0, "CheckBgImages", "1");

and

theDoc.SetInfo(0, "RenderDelay", "5000");  // You can change this value, just an initial test.

The second will delay rendering the PDF, giving the image a chance to download.

I had a similar issue and found it was caused by the size of the image file being too large.
