Change of font/size

[Pierre G]

Some parts of this message have been removed. Learn more about Nabble's security policy.

Hi ,

 

I generated a letter using data from database. In some circumstance (that I don't understand), some static text (not from DB) change their sizes,

I attached to picture to make it clearer.

The change starts at the sentence : "Service de Pharmacologie et Toxicologie cliniques".

 

 

Thanks in advance for any idea or way to debug the problem.

 

Pierre

NB : The code, jar (iText-2.0.8.jar) and machine are the same.

That doesn't clarify the problem. Are you embedding the font?
What about sending two PDFs so that we can compare? (It would be
interesting to see what font is used and what the content stream
looks like internally.) What about sending us a code sample so
that we can reproduce the problem?

> Thanks in advance for any idea or way to debug the problem.

He who has the code, can debug; he who doesn't have the code,
can only guess.

Thanks Bruno,

This is the code. The problem start in the paragraph "paragraphDocteurs", the font used is  stFont and is set in the
constructor.

Bruno,


Here are 2 pdf.
The only difference is that I add junk text (from db) in the "RÉSUMÉ CLINIQUE" part.
This make difference at the beginning of the document ....

Thanks.

Pierre

Looking at your code, there are still many possible causes:

Pierre Gilquin wrote:
>     private static Font grasFont = FontFactory.getFont(FontFactory.HELVETICA, 8, Font.BOLD, new Color(0, 0, 0));

This is a private static variable; can you make it a constant?
How to make sure it's not changed somewhere else in that (incomplete)
class file you've sent us.

This part could be written in a cleaner way:
>         Paragraph paragraphDocteurs = new Paragraph(
>             "Service de Pharmacologie et Toxicologie cliniques\n",
>             stFont);
>         Phrase el2 = new Phrase(

>         paragraphDocteurs.add(el2);
>         document.add(paragraphDocteurs);

Why are you working with \n and adding separate Phrases,
you risk less errors if you create Paragraphs instead of Phrases,
and add them to the document one by one. That's more efficient.
However, if this is the cause of the problem, you must be using
different iText versions and experience some font propagation
problem. Without the PDFs, we can't check the document properties
to find out if you're really using the same iText version.

But most of all, I'd like to see the content stream, more specifically
the operand used with the operator that sets the font and size.

br,
Bruno

You're welcome, thanks for the feedback.
Coming up next: the CellHeight examples sent by Glen Hamel.
I had scheduled a release for today, but if the problem
reported by Glen is a bug, I'll postpone the release till
it's fixed.

Bruno
