Format problem in PDF (text doesn't wrap) [message #89267]

I'm trying to display the content of a database text field containing a
long chunk of text. In preview and HTML modes the report looks great -
the text wraps according to the width of the text field. However, in PDF
the text spills over the page and doesn't wrap no matter how I adjust the
width of the field. I've tried using data and text report items and can't
seem to get it to work. Any help is much appreciated. Thanks!

Hi Maria,

I have the same problem but I found a solution that works for me.

As in my case this problem occures only with strings like this
VERY_LONG_TEXT_WHERE_ALL_IS_IN_UPPER_CASE_WITHOUT_BLANKS I use the following
peace of code to add the unicode character 'ZERO WIDTH SPACE' (U+200B) to
the output expression to allow FOP to break at that position.

The original output expression was row["EXTERNALID"] in my case, of course
you have to modifiy the code to output your database field.

if (row["EXTERNALID"].length > 25) {
length = row["EXTERNALID"].length;
row["EXTERNALID"].substr(0, 25) + "\u200B" +
row["EXTERNALID"].substring(25, length);
} else {
row["EXTERNALID"];
}

Be aware that this only works for PDF output as in the HTML output you may
see the "zero width space", but I think that depends on the encoding.

It would be great if the BIRT team could take some time to investigate on
that and provide a way to force a linebreak.

I hope this helps

Klaus

Does anyone know if the 2.0 release has fixed this?

At some point, in this newsgroup, one of the BIRT team said that FOP (the
PDF engine) was being replaced by a homegrown version for 2.0. However, I
have not heard anything about it since then and I didn't notice it in the
2.0 project roadmap.

María,

I'm working with Eclipse 3.1.1 and Birt 2.0M2 on Java 5

I'm sorry to tell you that the problem persists (It is'nt fixed). BIRT's
PDF viewer only wraps words. So, if you have a really long word, you have
a problem. If your 'big chunk of text' is all in a word (looks odd to me)
you are in a problem. If it's composed of normal words it should wrap. If
it does'nt, perhaps you have a non standard word separator (e.g a space).

Good luck

Does BIRT support the capability to wrap this code into a stand-alone
function?
