Operation times out.
at EO.Pdf.HtmlToPdfException.b(Exception A_0) at EO.Pdf.Internal.j2.d() at EO.Pdf.HtmlToPdf.a(j2 A_0) at EO.Pdf.HtmlToPdf.ConvertHtml(String html, PdfDocument doc) at EO.Pdf.HtmlToPdf.ConvertHtml(String html, String pdfFileName)
Happens on a large HTML post.
Code I'm using:
string sTemp = pSB.ToString();
string sImageFilePath = ConfigurationManager.AppSettings["LocalTempImageFilePathBaseUrl"];
string sPDF_File=ConfigurationManager.AppSettings["PDF_FileCreatePath"]+DateTime.Now.Ticks.ToString()+".pdf";
HtmlToPdf.Options.BaseUrl = sImageFilePath;
HtmlToPdf.Options.PageSize = new SizeF(8.5f, 11f);
HtmlToPdf.ConvertHtml(sTemp, sPDF_File);

Hi,
You can try to increase HtmlToPdf.Options.MaxWaitTime and see if that helps. If that does not, see if you can split the big HTML text into small segments and find out which part is causing time out. If it times out regardless, you can try to isolate the problem into a test project and send to us (let us know if that's the case so that we can let you know where to send). Once we have that we will look into it immediately and see what we can do.
Thanks!

Is the maxLoadWaitTime in seconds, minutes...?
thanks

Setting the MaxLoadwaitTime just creates a new error:
Exception of type 'System.OutOfMemoryException' was thrown.
at EO.Pdf.HtmlToPdfException.b(Exception A_0) at EO.Pdf.Internal.j2.d() at EO.Pdf.HtmlToPdf.a(j2 A_0) at EO.Pdf.HtmlToPdf.ConvertHtml(String html, PdfDocument doc) at EO.Pdf.HtmlToPdf.ConvertHtml(String html, String pdfFileName)
The html isn't very large, but it does have about 50 images. If I reduce the image size (width/height) not byte size, they are only 20-25k then the errors go away, but also then my images are much smaller than needed. I'll try to play around with this, but there still is an underlying issue.
thanks

Hi,
Huge images are a bit tricky because the amount of buffer needed to decode/encode/render them. The most reilable way is to split them into small chunks and then run ConvertHtml once for each chunk (ConvertHtml can continue output on the same page, so the chunks do not have to be on separate pages. In another word, you do not need to know where to page). You can also save each conversion’s result as a separate pdf file and then call PdfDocument.Merge to merge them into a single file once you are done with all the small files.
Another thing you can try is to reduce the image resolution. Most high quality images are at least 300 DPI. However screen is typically only 96 DPI, which is more than enough produce good result for human eyes on screen. So if your PDF file is primarily for viewing, then you do not need resolution higher than 96 DPI. Reducing the DPI will not reduce the image's dimension (width/height), but will reduce the data amount significantly.
Hope this helps. Please let us know if it works for you.
Thanks!

Thank you for the suggestions.
I have reduced the images width/height to an acceptable level, the images already are 96 DPI. I'll try the chunk method seems like that is the best fit.
thanks

Hi, You can not use root relative path such as "~". Only ASP.NET knows how to interpret that. Using our component inside an ASP.NET application does not mean our component will understand everything ASP.NET understands. If you changed the path and still gets time out, see here for more details: http://www.essentialobjects.com/doc/4/web/aspxtopdf.aspx#debugThanks!
