I upgraded newest version of EO.Pdf. (latest dlls 20.1.45.0 with new key)

EO.Pdf HTML to PDF took longer than expected sometimes, or it timeout with a blank content.
I have adjusted MinTimeLoad = 10 seconds and MaxTimeLoad = 35 seconds.


here is sample codes :
var options = new HtmlToPdfOptions
{
MinLoadWaitTime = 10000,
MaxLoadWaitTime = 35000,
AutoFitX = HtmlToPdfAutoFitMode.ScaleToFit,
PageSize = new SizeF(PdfPageSizes.A4.Height, PdfPageSizes.A4.Width),
OutputArea = new RectangleF(
0, verticalTopMargin,
PdfPageSizes.A4.Height,
PdfPageSizes.A4.Width - verticalTopMargin - verticalBottomMargin),
FooterHtmlFormat = "<span style='float: right;font-size: 12px;padding: 0;margin: 0 30px 0 0;'>Page {page_number}-{total_pages}</span>"
};
var pdfDocs = Enumerable.Empty<PdfDocument>();
foreach (var url in urls)
{

var pdfDocument = new PdfDocument { EmbedFont = false };
HtmlToPdf.ConvertUrl(url, pdfDocument, options);
pdfDocs = pdfDocs.Concat(pdfDocument.Yield());
}

your help is appreciated.

Thanks,

Hi,

After we upgraded to the newest version, we have an issue with pages data not being rendered on a DotNet application, we are trying to make PDFs from using url conversion. Page contain charts that dynamically generated from a database. Some page returns in second, some other pages take longer depend on how complex of the chart / query. Per your suggestion, we have monitor the traffic and nothing holding up in web server log.
The suggestion to use min-wait-time is also not working for our cases. The target pages to be converted into PDF may vary from single page to many, data-"heavy" pages, Thus in order to be sure, we would need to impose a min. wait time of several seconds. Data doesn’t load that slow, but if we go close to the actual load time, eo.pdf begins conversion before data is ready anyway making rendering of the dynamic portions of the page dependent on data-fetch being completed doesn’t work either and the result is back content for some data heavy pages, and the performance is slow.

Other option that we have tried: HtmlToPdfTriggerMode.Auto - per your definition “Automatically triggers conversion as soon as the page contents (styles, images, etc) are loaded “. This option is no longer working in the newest version. It worked in old version.
Would you please look into your HtmlToPdfTriggerMode.Auto for the newest EOPDF version?

Any suggestions are appreciated.

Kind regards,

Thank you so much for suggestions.
Per your instruction : https://www.essentialobjects.com/doc/pdf/htmltopdf/trigger.aspx,
I applied condition below to all my js script files.
if (window.eoapi && eoapi.isEOPdf())
eoapi.convert();

and added set TriggerMode = DUAL. (When TriggerMode is set to Dual, the converter will still wait for page contents to be loaded. The conversion will start only after page contents are loaded and eoapi.convert() is called )

It worked well from localhost. When I deployed to server for scheduler Quartz to run desks atomically , some decks are return and sending emails message with PDF contents. other desks are getting Time Out message

Message: System.Exception: Time out expired before the page can be loaded.

var pdfMerged = PdfDocument.Merge(pdfDocs.ToArray());
var stream = new MemoryStream(20480);
pdfMerged.Save(stream);
stream.Position = 0;

return stream;
}


Any suggestions are appreciated.
