Hi All,
If there is a ‘&’ in the content then the character next to the ‘&’ is missing in the PDF after converting to PDF using pd4ml.

Please help me to resolve this issue.

Thanks,
Ajit

Would you have an idea when this would be released? 1 month, 6 months, a year?

#29446

~1 month

But definitely this year.

#29448

The issue is not reproducible with the actual versions of PD4ML.
Which version do you use?

#29447

Awesome thanks.

#29400

v385fx3 solves the issue.

#29401

Thanks, the new version works great! I appreciate you addressing this.

Hi Support,

we are using pd4ml to generate pdf from html . but we are facing performance issue
at render method .. its taking 7 mins for 5MB file .below is my code please help us to overcome this issue .

=============================
java.io.FileOutputStream fos = new java.io.FileOutputStream(fileName);
PD4ML pd4ml = new PD4ML();

PD4PageMark header = new PD4PageMark();

header.setAreaHeight(-1);

header.setHtmlTemplate(pdfHeader);

PD4PageMark footer = new PD4PageMark();

footer.setAreaHeight(-1);

footer.setHtmlTemplate(footer);
pd4ml.setPageSize(PD4ML.A4);

pd4ml.interpolateImages(true);
pd4ml.overrideDocumentEncoding(“UTF-8”);
pd4ml.generatePdfa(true);
pd4ml.generatePdfForms(true, “Courier New”);
pd4ml.enableImgSplit(false);
pd4ml.setPageInsets(new Insets(10,40,10,40));
pd4ml.setHtmlWidth(1080);
pd4ml.adjustHtmlWidth();
pd4ml.useTTF( “java:Fonts”, true );//./WebContent/WEB-INF/lib/fonts
pd4ml.setDefaultTTFs(“Segoe UI”, “Arial”, “Courier New”);

pd4ml.generateOutlines(true);
pd4ml.enableImgSplit( false );

pd4ml.setPageHeader( header );
pd4ml.setPageFooter(footer);

pd4ml.render(new StringReader(pdfString),fos);

==================

Thanks & Regards,

A conversion duration primarily depends on HTML/CSS file size and its structure. So an HTML sample would help to analyze the issue in details.

Typical reasons of such performance issues:

– Huge CSS stylesheet: as we seen a couple of times, some “web optimised” HTML documents may include 2-3 Mb CSS style, tuned to suppress known banner exchange engines. The style makes no sense for HTML document layout, but makes CSS parser/runtime to spend quite a lot of resources to maintain the styles and it significantly slows down style resolving for a particular HTML element. Unfortunately CSS parser we use is not optimised to deal with extra big stylesheets.

– The entire document layout is built as a single table with tens or hundred thousands of cells. If the table is nested to another table – rendering takes 3 times longer; 2 levels of nesting – 9 times longer etc. For big documents we recommend to split a huge table to a sequence of smaller ones and avoid a table nesting.

If you are interested, a technical background of that is following: each cell width is calculated 3 times for MIN, MAX and optimal values. So every nesting level multiplies the “layouting” approaches to 3. If, lets say a content of a cell of a particular table row does not fit a column width calculated before, it needs to start table layouting again, taking into account a new condition.

Hi Support,

i have attached the html file which we are using to generate pdf . please have a look and guide me to solve the problem .

Thanks,
Vinay

I checked the document sources.

Well, as I suspected the document layout is built as a single table. The table cells also include multi-nested tables (up to 4 nesting levels).

It should help a lot if by the HTML document generation (hopefully you have a control over the process) you can omit the “main table” – just output its nested content.

I am trying to make PDF&RTF files from html page.

in example there is a string to set page orientation:
pd4ml.setPageSize( landscapeValue ? pd4ml.changePageOrientation( format ): format );

it work perfect with PDF, but have no effect with RTF format.
What can be wrong?

P.S. I am using PD4ML 385 Pro

#29452

For the time being, PD4ML does not support the feature by RTF output.

Also I am not sure if RTF file format implements such a feature. Do you have an RTF sample (probably created with MS Word or OpenOffice) to confirm it is possible?

#29453

Thank you for your fast answer

Attached file is .RTF, but it have landscape orientation in Word 2007 and OpenOffice 4.0.1 at my computer

#29454

I guess I misunderstood you first time. PD4ML does not support a dynamic format change: for example, the first page is portrait, the second is landscape.

To avoid possible code errors, try to define format explicitly, without conditions:

Portrait:
pd4ml.setPageSize( PD4Constants.A4 );

Landscape:
pd4ml.setPageSize( pd4ml.changePageOrientation( PD4Constants.A4 ) );
