Hi, When rendering a large page (+20 pages) to PDF, we got an internal error: (tested under EO.PDF file version 5.0.59.2, latest release a.t.m.). Can this be fixed in a new release? It there a workaround for now possible?

Hi,
I just downloaded and installed the new version, but this is still an issue.
So we get the same error on the last version (EO.Total 2013.0.72, 5.0.64.2 is the dll version)

Hi,
In that case please try to isolate the problem into a small test project and then send the test project to us in zip format. Once we have that we will be happy to investigate further. We will PM you as to where to send the test project.
Thanks!

We have same issue and we also try out newest version of EO.PDF component (5.0.68.2). Our website page has more than 82 pages (A4) if we will try to print it. Our page contains more than 400 highstock charts (see http://www.highcharts.com/products/highstock)

For your information:
In our case we also use canvas (jqplot library). The page was +50 pages an with +50 canvas objects.
For us it wasn't possible to provide a (small) testcase

Please do NOT post our emails publicly in the forum. The reason is not because we do not want to publish our email address, but because posting in the forum will cause the email address be harvested by bots and eventually get flooded by spams. Thanks!

However please be considerate while posting in the forum: 1. Unless you are sure that your question is related to an existing thread, we recommend you to post your question in a new thread. Do not just reply a totally unrelated thread; 2. Please do not just post everything that you are asked to do here and expect that we will be able to do for you. Take a look of the documentation and sample first. Most likely your questions are already answered there; 3. Please maintain basic manner and respect to all other users and to us in all your post and pay attention to your tone and language. In order to provide the best service for all of our customers, we need to maintain a friendly and respectful atmosphere here, and that requires effort from everyone. I hope you understand. If you still have any questions after you take a look of the documentation and sample, please feel free to make a new post and we will be happy to help you further. Thanks!
