Where can I obtain barcode fonts? I found a link[2] and I'll try some
of the files there.
I've tried both 3 of 9 fonts from [2] and [3] and the Code128 font from
[2]. All work fine, although the TTF font causes two warnings because
of
missing TTF tables.
Works for me now, see below...
UPDATE: I've been trying, but I'm getting errors ('[ERROR] unknown
font
Code128JK_A,normal,normal so defaulted font to any' or '[ERROR]
unknown
font FREE3OF9,normal,normal so defaulted font to any', depending on
the
FONT I'm trying to use). I downloaded a barcode font from here[3], and
followed the instructions on the FOP Font Page[4].
Here's the relevant portion of my conf/userconfig.xml file:
fontBaseDir
/Users/Shared/_WebDLs/barcode_fonts
embed-file takes the PFB, not the PFM!!! The PFM is only for generating
the font metrics XML. The PFB contains the actual font.
Thanks! I didn't know which part I needed to include there. Now that I
look back at the Fonts page, there is an example which has .pfb. Sorry.
It doesn't make a big difference but set kerning to "no".
Done!
kerning="yes">
This is the relevant XSL-FO for using the PFM:
F62P-0704
Works for me.
Since I was having trouble using the PostScript font, I tried using
TTF. This is the relevant XSL-FO for using the TTF:
F62P-0704
Please let me know if I need to provide any other info.
Dumb question: Have you supplied the userconfig.xml on the
command-line?
That's my only explanation for your problem. If I omit the
userconfig.xml I get your error messages. Besides that I've done
nothing
special while generating the XML metrics. I've used practically the
same
configuration (including fontBaseDir). I've even copied snippets from
your e-mail to reproduce the problems.

That was the culprit, so I guess it wasn't a dumb question. It was me
being dumb not including the config file. My only 'excuse' is to say
that I've never had to use a config file before now (although I'll be
using it in the future to play with strokeSVGText...)
Thanks Jeremias!

No, you can't. The FOP extension doesn't have access to the page number
ATM.

So i am now trying to incorporate the demo font they provide into FOP but I get the following exception trace when I use fop's TTFReader class in order to generate the font metrics file: C:\software\fop>c:\software\jdk131\bin\java -cp .\build\fop.jar;.\lib\batik.jar;.\lib\xalan-2.0.0.jar;.\lib\xerces-1.2.3.jar;.\lib\avalon-framework-4.0.jar;lib\logkit-1.0.jar;.\lib\jimi-1.0.jar org.apache.fop.fonts.apps.TTFReader -enc ansiC:\WINNT\fonts\SadC128b.ttf barcodettfcm.xml TTF Reader v1.1.1 Reading C:\WINNT\fonts\SadC128b.ttf...

It is trying to create a character map for unicode I believe ! Anyone has an idea ? Pascal.

The API I propose you use something like the perl module Code128.pm for the algorithm and then from the generated numbers it is real easy to generate svg or fo for the bar code itself.

re: barcodes
Hi, I am using IdAutomation API (There also exists JBarCodeBean) in order to produce (code128) barcode images (either as GIF or JPEG format). The API is very easy to use. I use an fo:external-graphic tag to integrate them. On the other hand, the barcode reader I use has some difficulty to read them. It reads them ok but it seems that the generated images are of average quality and it takes the barcode reader a long time to read them. Another issue is that it is not easy to produce a image fitting a given size. You will have to play with multiples of the printer resolution. In fact, I generate big images in order to keep the quality acceptable. Apparently, the use of fonts makes better quality barcodes (They used that with the application that we are trying to replace). I have not investigated fonts as I was too short on time and the image based solution seems to be accepted (at least as of now, but that may change). I have been told that a specific algorithm is needed in order to encode the barcode value into a string of characters (that will be used for input to the font and FOP). Another reason for which I did not use this type of solution is that this algorithm is contained within a DLL and we do not want to go playing with DLLs (We are using a Java Application Server and it is not recommended to use DLLs in an AppServer). If you try fonts, let me know. I may also have a go on them if I have the time for it and/or if the guys here tell me that the barcode quality is judged unacceptable (too slow to read). Hope I gave few some good feedback. Pascal
