#29897

Try to switch debug on (pd4ml.enableDebugInfo()) and compare debug output for v3.7 and v3.10. It should list TTF fonts it loads. I assume you evaluate Pro version of PD4ML v3.10 as PD4ML Std is not capable to use TTFs and to render international scripts.

#29898

Thanks for the quick response.

Yes you are right we are evaluating pro version of pd4ml v3.10.
Is there a change from v3.7 to v3.10.6,how do we solve this issue?

Logs while generating pdf in both the version.
hope this helps :

Hi PD4ML support team,

Kindly help us here, as its very important for us to resolve above issue to go ahead with upgraded version.

#30146

Hi,

Display inline-block is not supported. See the list of supported CSS properties here
http://pd4ml.com/css.htm

Vertical-align is supported. What are you trying to align?

#30143

Float is supported so you could float your unordered list items?

#27191

Hello everyone, I’m having a problem generating my PDF from PD4ML. I generate the whole HTML and e error: javax.servlet.ServletException: java.lang.IllegalStateException: Stream handler unavailable due to: null when trying to execute line 9 of the command below:

1. PD4ML html = new PD4ML ();<br /> 2. Dimension landscapeA4 = html.changePageOrientation (PD4Constants.A4);<br /> 3. landscapeA4.setSize (595, 842);<br /> 4. html.setPageSize (landscapeA4);<br /> 5. html.setPageInsets (new Insets (20, 10, 20, 10));<br /> 6. html.adjustHtmlWidth ();<br /> 7. html.enableDebugInfo ();<br /> 8. Base URL = new URL ("file: C: \ gip_upload \ upload \");<br /> 9. html.render (isr, fos, base);<br />

More interesting is that my HTML starts with the tags “ … “. That way it gives the error mentioned, but when I remove these tags it manages to create the PDF however unconfigured and out of standard.

#30144

Or go PD4ML v4: https://github.com/zxfr/pd4ml-examples

#30152

Could you also publish initialization of isr and fos (it is not clear what is behind them) as well as full exception stack trace?

#27192

We are using pd4ml java library to convert html to pdf, I need to display multiple HTML paragraphs. Paragraphs should display next to each other without any line break. If I set paragraph style “display: inline” it works well in browser. When it’s converted to PDF, display is not same as it’s creating new line before paragraph. Following release notes I also tried “display: inline-block”, but that didn’t work either.

Football is a family of team sports that involve, to varying degrees, kicking a ball with a foot to score a goal. Unqualified, the word football is understood to refer to whichever form of football is the most popular in the regional context in which the word appears.

There are a number of references to traditional, ancient, or prehistoric ball games played by indigenous peoples in many different parts of the world.[3][4][5] Contemporary codes of football can be traced back to the codification of these games at English public schools during the nineteenth century

The expansion of the British Empire allowed these rules of football to spread to areas of British influence outside the directly controlled Empire.[8] By the end of the nineteenth century, distinct regional codes were already developing: Gaelic football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage.In 1888

The various codes of football share certain common elements and can be grouped into two main classes of football: carrying codes like American football, Canadian football, rugby union and rugby league, where the ball is moved about the field while being held in the hands or thrown

Hi,
I’m trying to implement setHtmlTemplate method. This is not working in my case.
e.g –
final PD4PageMark pdfHEADER = new PD4PageMark();
pdfHEADER.setHtmlTemplate(“test“);

Please provide help.

Thanks.

#27194

pd4ml is not recognizing font-size in rem (root em).

//works fine
Winter is coming – font size: 24pt
Winter is coming – font size: 32px

//font size is ignored.
Winter is coming – font size: 1.6rem

Is this supported by library, any idea how to solve this problem.

Pdf4ml: 3.10.6
Chrome: 66.0.3359
Platform: Windows 10 & Java: 1.8

#27195

We are having an issue since upgrading to the latest version of PD4ML.

Every so often (1-2 times a day), our application ends up hanging and a thread dump at the time reveals there are hundreds of hung requests waiting for the PDF generation. I think that Apache literally runs out of request threads.

An example of the stack on each of these threads is below.

Any idea why this would be happening, or how to get around the problem?

#30158

Hmm… First, PD4ML does not start new threads – so the hundreds of hanging thread should match a number of conversion requests.

As I see from the stack trace, it hangs on a network operation – it is difficult to say why it cannot read data from a socket. Did you check logs on the remote side, where it tries to read the data by HTTPS from?

#30159

The request is firing back into the same application (to get the HTML version of the page I’m converting into a PDF).

Interestingly there is no sign of any other requests in the thread dump apart from the initial user requests for PDFs. So it looks like the request from the PDF conversion isn’t making it back to the application.

This either means that the request isn’t getting out (or back in) from the PD4ML component, or perhaps the system is somehow locked up with all the initial user requests that the resultant HTML requests can’t get in. This may also explain the fact that this issue is intermittent.

Can you suggest anything?

[PD4ML]

#30160

It seems it hangs by an attempt to read cookie data from HTTPS response header. Not that easy to debug…

As a general recommendation limit the timeout for the network operations:

HashMap map = new HashMap();
map.put(PD4Constants.PD4ML_SOCKET_TIMEOUT , "60000"); // in ms
pd4ml.setDynamicParams(map);

That should help to avoid the running out of threads. But it does not address the problem reason.

The best workaround would be to avoid HTTPS protocol by the local data exchange at all. A reference like <a src=”/images/logo.png”> is more preferable than <a src=”https://myserver/images/logo.png&#8221;>

Please take into account, the link like <a src=”https://myserver/images/logo.png&#8221;> can be built implicitly from <a src=”/images/logo.png”> and <base href=”https://myserver/&#8221;>. In the case an overriding of the base with PD4ML API call parameters should help.

If the HTTPS is a must, you have to investigate the network issue reason… We need some more input
