RE: trying to extend FOP to handle Barcodes
thank you Jason, I have found a servlet that does the same, but I can not convert the image in the pcl output file. I need the image to be in the pcl output file to send to the printer. Thank you. -RafTired of spam? Get advanced junk mail protection with MSN 8. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Raffi, I have a servlet that i wrote which takes as parameters a string to encode as a barcode, the barcode type, and the size in pixes you want the barcode to be. It returns a GIF image. Jason - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: trying to extend FOP to handle Barcodes
I haven't done this before you I can try to give you some pointers: 1. Have a look at this page: http://xml.apache.org/fop/extensions.html 2. I'd implement your extension as fo:instream-foreign-object, like SVG is implemented. Example: http://mybarcodeext";>12345 3. Have a look at the following classes as a template to add support for your extension: - org.apache.fop.svg.SVGObj - org.apache.fop.svg.SVGElement - org.apache.fop.svg.SVGArea - org.apache.fop.svg.SVGElementMapping (to register the extension) 4. Last but not least you will have to either change or subclass org.apache.fop.render.pcl.PCLRenderer to support your extension. The renderer is not really finished especially what SVG is concerned and that's why there is still something to do. Other renderers like PDF will help you to make it work. I hope that helps a bit.
