I am afraid percentage height values are not supported. In PDF generation context not always obvious what should be taken as a basis to calculate relative height.

For example:

<body>
<img src="pic.png" height="100%">
</body>

In the case image height depends on HTML body height, but html body height depends on image height.

https://pd4ml.com/cookbook/pdf-attachments.htm

So I tried the inline option but pdf:attachment tag always asks for src attribute.. If I leave it empty:

<pd4ml:attachment description="attached.txt" src=""><br /> data:base64,YSxiLGMsZCxlDQp2YWx1ZSAxLCB2YWx1ZSAyLCB2YWx1ZSAzLCB2YWx1ZSA0<br /> </pd4ml:attachment>

I see just an icon and not the attachment. Do I do something wrong?

In the next version it will suppress the version-, JVM- and OS- specific info when a document ID is overridden with System.setProperty(“pd4ml.document.id”, “…..”) call.

Normally we publish monthly maintenance updates. The most recent release was few days ago. I expect a new version is to be available close to the middle of March.

#29669

Try

<pd4ml:attachment description="attached.txt"
src="data:base64,YSxiLGMsZCxlDQp2YWx1ZSAxLCB2YWx1ZSAyLCB2YWx1ZSAzLCB2YWx1ZSA0"/>

Just tried to add such thing – failed. As soon as you specify div inside header as position:absolute the content (which is img tag) goes over it and covers it.
Is there any way to implement such thing? I want to “put” a stamp over the image.
Thank you in advance

#29625

Thank a lot for all your answers.

All given solutions seems perfect !

Can’t wait to see your new release !

#29664

Just tested it and indeed is solved, thanks!

Hi there,
I try to convert this html code:

<br /> <p><br /> Dear Jack,<br /> <br />this is line 1.this is line 1.this is line 1.this is line 1.<br /> </p><br /> <p><br /> this is line 2<br /> <br />this is line 3<br /> </p><br />

Why there is so much space between p tag in VAND generated pdf?
Is there a way to reduce it?

#29244

Hi Team,

Are you planning to use some stream or writer so it can handle big pdf. 17 MB html file should not be big. Ideally framework should allow 1 GB html file to pdf.

Thanks
Ram

I resolved with {padding:0; margin:0} styles added to p and div tag.

#29674

Probably a removal of paragraph margins completely is not always a good idea. You could define/override styles only for particular cases, for example:

P + P, DIV + P { margin-top: 0 }

resets top margin, only if a paragraph follows other paragraph or DIV

#29245

I am afraid, a streamed or serialized HTML-to-PDF conversion is not possible – a document must be rendered in memory completely before it is converted to PDF. There is always a possibility that at the end of a document there is an HTML tag or a content portion, which would require a complete document re-layouting.

#29626

Hi !

We’ve tried your new version 3.9.5, it doesn’t allow to overwrite pdf metadata.
Furthermore, when we look at the source code, we don’t see any change regarding our case.
Thus, could you give us some precision regarding which version will “permit the suppression of the version-, JVM- and OS- specific info when a document ID is overridden with System.setProperty(“pd4ml.document.id”, “…..”) call” and when it’ll be able.

Best regards,

PD4ML Support team,

Thank you for an excellent product.
I was able to use PD4ML to create PDF from HTML and was able to merge PDF documents created by PD4ML easily.

On the other hand, I got a Java.lang.NullPointerException error when I tried to merge a general PDF file that was not created by PD4ML.

Do you have any suggestion or do you have a secure location I can send the PDF in question to you ?

Thanks !
