For the time being there is no workaround.

HTML-to-PDF conversion process consists of 2 phases: Initially PD4ML renders HTML document layout for a “screen device”, whose height is unlimited. At this point page breaks are not taken into account. After that the rendered content is “printed” to PDF output device (or Image device, or RTF device etc) and depending on a particular output media nature and dimensions, page breaks (or “page-break-inside: avoid” directives) applied.

What you actually need is to reflow the text depending on an actual image position, and the actual image position depends on a page break position. So during the phase 1 we need a position info, which will be known only during the phase 2. That is a very big challenge to the current PD4ML architecture and we are even not ready to estimate needed efforts yet.

Hello,

I am attempting to use the “fix_base_path” tag in order to add a domain name to selected html links. My current code is such:

<pd4ml:fix_base_path<br /> pattern="/css/"<br /> basePath="http://mydomain.com"<br /> addSessionID="false"<br /> >

This only replaces links that start with “/css/”. However, I would also like to replace links that start with other directories, such as “/img/” or “/js/”. Is there a way to add multiple patterns to this directive, or to provide the pattern in such a way that it can match other directories?

Thank you for your assistance!

Best Regards,

Try do define multiple nested tags with needed patterns.

<pd4ml:fix_base_path pattern="/css/" ... >
<pd4ml:fix_base_path pattern="/img/" ... >
<pd4ml:fix_base_path pattern="/js/" ... >
Content to apply the tags to
</pd4ml:fix_base_path>
</pd4ml:fix_base_path>
</pd4ml:fix_base_path>

On the other hand recent versions of PD4ML are able to resolve absolute web paths via ServletContext. I would recommend to add debug=”true” to <pd4ml:transform> and ispect STDOUT what it tries to load and whether the URLs are correct.

Thanks, that worked perfectly!

I was trying the “debug” option, but the referenced paths were still relative. Plus, I wanted to strip out the jsessionId from the resulting URL …

However, nesting the tags did the trick. Thank you for the quick reply!

Best,

Hi, I am trying to convert a HTML-styled String (for instance: “<HTML><BODY>my text to show</body><html>) to a pdf using streams:

StringReader isr2 = new StringReader(myhtmlstringl);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
pd4ml.render(isr2, baos);
if I use a fieoutputstream, the pdf is created but show a blank page.
and if I use the bytearrayoutputstream, what can I do for show the pdf-result in my webpage.

PDF format versions are backward compatible. PD4ML outputs PDFs compatible with Acroread 5 and newer. (Even if you use Acroread 4, it will ignore all features it does not “understand”)

Acroread 9.1 should introduce no problems at all, so no PD4ML update is necessary.

#28251

Thank you that works fine!

Unfortunately PDF standard provides not much control to optimize device-specific print jobs.

For example: if your PDF document has bulky images it depends on the printer supported features and the printer driver whether the image will be sent to print as an unpacked array of pixels or in its original compact format (JPEG, PNG).

Among PD4ML examples https://pd4ml.com/examples.zip there is PD4MLBySslServlet.java class, which ilustrates how to use PD4ML in web scenarios (just ignore SSL stuff there).

At first glance your Java code seems to be correct. So I would suspect source HTML as a reason of blank PDFs. Do you really have opening tag at the end of your HTML code? Please try to remove it – it may confuse the HTML parser.

I am unable display the Greek letters θ, ß in the generated PDF
I had tried with both Unicode, ASCII codesi in Java, but the same codes are getting displayed in the generated PDF.

What is the solution to display the Greek letters in the generated PDF?

You need to utilize TTF Embedding feature of PD4ML Pro

Hello,
I have charts displayed on my page. I want to export them also in the pdf generated. Please help me regarding the matter. If sample code is provided would be a great help. I am using amCharts to display charts on my pages.

Thanks & Regards

I tried a variety of JDK versions, but was not able to provocate an with any of them URL-length problem.

Now I suspect encoded URL parts wrolly interpreted. For example “%25” is auto-replaced with 0x25 character there. Could it be a problem?

Try a long chart path without such %NN patterns. Does it work?

With PD4ML Pro you may do that by inline footer definition:

<b>All rights reserved. Powered by PD4ML</b>

With PD4ML Std it could be done via API call. See more about footers/header:

html-pdf-faq-f1/pdf-page-headers-footers-definition-options-t41.html

#27664

The API call is intended for that:
