barcode via Dynamic Image [message #364730]

Hi,

i want to embed Barcodes by generating them on the fly as images with a
barcode java library and send the raw image data to Birt.

I saw that an image in birt can be from a dynamic source. Has anyone
ever done this? In Birt you can select a DataSet (why a dataset) or a
Report Item for an image.

So normally i would do in my calling java program:

task.getAppContext().put("imageRaw",
someByteArrayOutputStream.toByteArray());

So i would pass a byte[] to the birt context and bind this to a DataSet
or something else....

Do you think this will work? Anyone done something similar?

We're using BIRT to generate barcodes, but I've been using barcode fonts
and embedding the fonts in PDFs. We've gotten this font based method to
work with Code39 and Code 128 fonts.

I'd be interested in using images as you describe if you ever get it
working.

Hi, Marc.
I have met the similar question as yours. You may have a try with Onbarcode's Java Barcode Generator for Eclipse BIRT which provides several methods to generate and print barcodes in Eclipse BIRT reports.Hope it helped you.Good luck for you!

Onbarcode.com is a really excellent website which provides high quality linear and 2D barcode generator, reader and scanner in .NET AND JAVA applications. I conclude from what I have used. Recently, I find another one(Terrek.com) which is as good as Onbarcode. It is much cheaper with FREE version to try. You may have try it in someday! Good luck!
