<p:barCode> seamPDF + iText barcodes

ivanflorentin Apr 6, 2007 11:33 AM

I want to create a tag <p:barCode> to put tags on a PDF document using iText barcode generator. Itext in Acction is very clear about how to print barCodes.
I have a requirements however: It should be possible to place the barcode anywhere in the document. give an absolut position referring to the page size and orientation.
Can somebody guide me thru the seam source to accomplish it?

As far as I understand I just have to extend org.jboss.seam.pdf.ui.UIRectangle or even org.jboss.seam.pdf.ui.UIImage.

I never used iText & Barcodes but if you can convert your barcode to com.lowagie.text.Element you should be able to show it with p:element (have a look at http://www.jboss.com/index.html?module=bb&op=viewtopic&t=105900)

I have a working basic implementation of the tag if anyone is interested, it supports absolute positioning/rotation. It has all the functionallity I need now but I plan to extend to most of the underlaying implementation.

Please to open a JIRA case and contribute the code back. I can see how barcode generation might be useful to a lot of people.

I created a case and uploaded the files, note that I only need code128 type of barcode at this moment, so I didn't test much the other types. There is also an example of use in the package.
The functionality for code128 is also not complete noe but i expect to expad it in the following days.
It supports absolute positioning and rotation to be able to place the barcode outside the document area

<p:barCode type="code128" code="absolute" xpos="200" ypos="300" rotDegrees="45"/>

coordinates are in points from base-left of the page, rotation is in degrees.
