Problems with viewing report as PDF and also in Preview [message #654834] Thu, 17 February 2011 11:22 Go to next message

Hi everybody,

recently I have started to use Birt to create reports from a database of research groups.
I have detected some problems when generating a PDF and also when making a preview of the report, due to long lines that appear in the database.

In my report, the data from the groups are collected in a table. In some cell I have added a grid with all the information. The problem is that when making a preview or generating the PDF, in the cells of the grid only the first line is shown, the rest of the content is cut off.

If I choose the option "View as DOC" all the contents in the table are shown but I have to resize the cells.

Do anybody know how to solve this problem with the PDF generator?

Thank you very much for your help.

Best regards

Is there any whitespace in the string? You may want to look at this:
//RE API method
http://dev.eclipse.org/newslists/news.eclipse.birt/msg30589. html
PDFRenderOption options = new PDFRenderOption();
options.setOption(IPDFRenderOption.PDF_HYPHENATION, true);
options.setOption(IPDFRenderOption.PDF_TEXT_WRAPPING, true);
options.setOutputFileName("output/resample/wordwrap.pdf");
options.setOutputFormat("pdf");

or
//javascript substring

Thank you Jason for your help, but I would like to know how to change the option in PDFRenderOption because I think that I don't have the source code.
I am using the the gui environment of Birt.
Again, thank a lot.

Regards,

Teresa.

Hi Jason Weathersby,

Can you please explain how it script work and hot they get parameter - longStr and width?

function wrap(longStr,width){
length = longStr.length;
if(length <= width)
return longStr;
return (longStr.substring(0, width) + "\n" + wrap(longStr.substring(width, length), width));

longStr I believe in that example is whatever you pass in as a value.
For example in an expression wrap(row["mydata"], 20)
Width is the max length you want the string to be before inserting a new
line.

Teresa,

Currently there is no option to change this in the Viewer unless you
modify the source for it. Can you log a bug for this?

Are you using the API or the Viewer? If you are using the Viewer are
you going to modify the viewer source code?

What is "the API"? For viewer I am using Actuate iPortal. I have little experience in creating Birt report, if you have example, how I can modify the viewer source code, please give me it.
Thanks!
