PDF pagination problem [message #231757]

Hi,

I'm having a problem with PDF pagination in birt. I have a table with
lots of rows and inside this table I have an another table with 2-20
rows. When generating a PDF file of this it splits some of the table
rows into two pages and this looks ugly. Is there a way to make BIRT
do a page break after a table row if the next row doesn't fit into the
page.

I know that it is possible to do this by grouping and counting rows in
javascript, but is ther any other way?

Did a bit of investigating and apparently there is no way to do
this. Is this feature planned on future releases of BIRT because this
is quite important factor when printing PDF:s. IText that BIRT
apparently uses for generating PDF:sshould support this.

As this is about iText, I want to clarify that there are different
ways to use iText.

When using high-level objects, we're talking about PdfPTable.
As described on p178-179 of the book 'iText in Action', the
PdfPTable object has three options:
(1) split the table BETWEEN rows (what you desire)
(2) cut a row in two parts (what you experience)
(3) omit a row that doesn't fit (I don't ever use this, but
people asked for this and we implemented it).
(1) is the default option;
(2) can be set with setSplitLate(false);
(3) can be set with setSplitRows(false);

When using low level PDF functionality, it's up to the tool
(in this case Eclipse/BIRT) to decide if the content is written
on the current page, or if a new page is needed.

Any way: you have to take into account that some people
will WANT to have the row split in two parts, or even
throw away a row that doesn't fit the page. So an extra
parameter will be needed.

Bruno
