As I wrote before the scale factor is computed this way:
scale = (pageFormat.width – insets.left – insets.right) / htmlWidth

In your case a switch from portrait to landscape means change of pageFormat.width from 595 to 842. You need to correspondingly/proportionally increase htmlWidth parameter.

Problem

---

The function call of “Pd4ml.render” take long for processing HTML with large PDF attachment.

System Info

---

Windows 2003 Standard Edition
Lotus Domino 7.03 FP1
PD4ML Java Library Pro

Background

---

Our program is designed to generate PDF from Lotus Notes Email Document.
There are few steps to doing that:
1) Export a lotus Notes Document with attachment to DXL format file.
2) Use javax.xml.transform.Transformer class to convert DXL file to HTML file.
3) use pd4ml.render() function to convert HTML file to PDF.

Currently, we found that the time required to completed the function call “pd4ml.render” when the input HTML is transformed from Notes Document with a large size of PDF file attached. (e.g. 12MB PDF file need 11 minute to finish this function call).

Please kindly advise whether there is any method to speed up this case.

Part of the Code (full code of the agent is attached)

---

pd4ml.enableDebugInfo();
java.net.URL base = new java.net.URL(“http:/yahoo.com”);
java.io.StringReader isr = new java.io.StringReader(“file:” + readEncFile(inputHTMLFileName, “UTF8”));
System.out.println(“17”);
pd4ml.render(isr, fos, base, “UTF8”); //The time between the printout of 17 and 18 shown up is about 11 min
System.out.println(“18”);

You need to utilize TTF embedding feature of PD4ML Pro:

pd4ml-html-css-pdf-tips-tricks-f7/ttf-embedding-t42.html

#27877

Please request the most recent XSL stylesheet and the reference agent code from support pd4ml.com by email.

I suspect the following: the default XSL stylesheet of the demo Notes database represents attachment files as
<pd4ml:attachment src="data:a-lot-of-base64-data">

It takes a lot of time to parse such huge attribute value (if we are talking about tens of megabytes) and constantly reallocate string to store it.

The most recent XSL allows either to temporarily store the attachment to TMP directory and to refer to it from the attachment tag: <pd4ml:attachment src="file:/tmp/xxxyyyzzz.bin"> or to represent the attachment as tag body <pd4ml:attachment>data:a-lot-of-base64-data</pd4ml:attachment>. Both approaches are intended to solve the performance issue.

Hello,

we have documents where an image is inside of a <td> in a tablerow and in another <td> of the same row we have some multiline-text. See problem_html.jpg with an image of the look.
When this image now requires pd4ml to put it on the next side because of the noimagesplit-option and the text in the other td also continues to this page, the text isn’t continued at the top of the side but at the bottom of the image. See problem_pdf.jpg for an image of the same part.
I’ve also included the original htm-code inside of problem.zip.

Is this a problem of pd4ml or can we change anything inside our html-code to prevent pd4ml from doing this?

#27878

Dear Sir/Madam,

Firstly, thank for your prompt reply.

I have asked your company’s email support service to give me the new XSL. Your colleague, Igor had gave me the new XSL file. However, there some problem found.:

1) I found that new XSL file does not have the tag (<pd4ml:attachment src="file:/tmp/xxxyyyzzz.bin">) which you mentioned in last reply.

2) The XSL file that your colleague, Igor sent to me that need me to try to un-remark the line No. 298 and 308 in order to use. I have tried to keep the remark and un-remark these 2 lines. But both does not improve my pd4ml.render() function. It still cause 10-11 minutes to complete. Also, it need me to increase Min heap size of domino to around 800MB in order to successfull run. My original setting of around 500MB Min heap size will cause the domino agent throw out of memory exception.

3) Then I try to change my agent to use the one that Igor send to me. However, I found that my current Jar library does not the API “generatePDFA”.

Please kindly advise what further step I can do in order to improve the speed.

Thank you very much!

Attached the XSL and agent code that Igor sent to me.

#27879

Please forward the questions again to Igor. Missing of generatePDFA() method, means you use old version of PD4ML (probably it is cached in the database).

It would also help if you uncomment DXL dump method in the agent code and send the output to us. It should help us to reproduce the issue and to provide you with a tuned XSL stylesheet.

#27891

In order to avoid such issues, I would recommend not to use enableImgSplit(false).

A better approach would be to apply “page-break-inside: avoid” CSS property to particular table rows. In most of the cases it is also harmless to apply

TR {page-break-inside: avoid} to entire document.

Hello… I am evaluating this product. I tried to run a few examples and compare it with others. So far this is really good. However, one of the url I tested was not properly converted. It seems that some CSS instructions were not followed.

The url I am referring is http://www.blazersedge.com. I viewed the source and it has at least five CSS links but noticed that only one css was loaded by PD4ML. Can you please set me to the right directions how to convert this page properly?

Obviously the site returns layouts and styles, optimized for particular client browser – which is actually good practice.

PD4ML does not declare itself in HTTP request as any of the major browsers, so it receives a very basic HTML/CSS version (probably a version for mobile clients). As for me the HTML is converted correctly. See attached.

#27893

No it was not… I have attached how another converter does it. Also, now I noticed that PD4ML from this website is in MOBILE BROWSER mode (look at the debug output again). If so, how do we resolve this?

Well… I can’t attached the file since it’s 1mb in size.

#27894

A lot of “other” converters use MS IE or Mozilla native DLLs to load and render HTML. So the site returns versions, adapted for the browsers.

PD4ML uses our proprietary HTML rendering engine (100% Java, also ported to managed .NET code). It is PDF-output-oriented and it does not support JavaScript. Despite the product name “HTML-to-PDF converter”, PD4ML is not intended for web sites capture. Our goal is on PDF side: it is to allow you to define PDF layouts of any level of complexity with a language everybody knows – HTML.

If you plan to convert popular interactive web sites to PDF, most probably the result will disappoint you. A specialized PDF print driver will do the job better.

#27895

Thanks for the insight. You’ve been very helpful. Thanks again.
