Adding fonts
I've added an EAN13 font to FOP using the procedure described on your web-pages and everything seems ok until I try to open the resulting PDF document. Then Acrobat Reader complains that an error occured and the page cannot be opened. I know this has to do with the font's and I noticed that the EAN13 font was not embedded so I've tried to add it to the Acrobat resource catalog but the problem is still there. Any ideas?

A bug in Xalan. I reported this last (or was it this) week and the fixed

In the "draw-bars" template of "barcode-EAN-SVG.xsl" there is a test that determines if there are more bars to draw, like this:
<xsl:if test="substring($bar-and-space-widths, 3)">
I suspect that this test would normally return false if the string is shorter than 3 characters, but this is not the case when using Xalan. So I've replaced the test with the following code:
<xsl:if test="string-length($bar-and-space-widths)>=3">
This works OK, but now FOP reports a NoSuchMethodError in SVGRenderer.applyStyle().

Yes, I've tried the SVG type... It does not work. I keep getting StringIndexOutOfBoundsException's when performing the transformation. I've so far narrowed it down to the SVG stylesheet.

Actually, there are _TWO_ different stylesheets there (sharing the pattern
calculation subroutines). One generates XSL FO - representing barcodes as an
<fo:table>. The other one produces the same pattern as plain SVG - something
like this:
<svg:svg height="..." width="...">
<svg:rect height="..." width="..." x="..." y="..." style="fill: black;"/>
....
</svg>
Have you tried to insert this into your document through
<fo:instream-foreign-object>? I suspect this is an easier (and, IMHO, more
natural) way of handling barcodes, as you don't need any table support at all.
Regards,
Nikolai

I didn't check Nikolai's style sheets, but I would guess the problem is that
they use height property on fo:table-row and FOP doesn't implement it yet. I
just added the height property to TableRow.java (as a quick hack) when I
wanted to test my style sheets that generate Code 128 C bar code and it
worked ok in my case. Anybody working on height property in fo:table-row?

I'd like to draw your attention to this page:
http://www.renderx.com/barcodes.html
It is a barcode generator for EAN8/EAN13/UPC-A/UPC-E written in XSLT. Thanks to
Andriy Palamarchuk, it can now produce SVG output; you could insert an SVG
graphic instead of a custom font into your FOP document. The thing is completely
free.
Sorry for a shameless self-promotion :-(.

The problem might be in the XML file generated by the PFMReader tool.
There are certain flags that may not have been correctly set by just
interpreting the PFM file. Maybe there's a bug.
If you have Adobe Acrobat (not just Reader), you can generate a file
containing a barcode using Word for example. When you open the resulting
PDF in a text editor you should be able to read the flags for the font set
by Acrobat. Then you can adjust the XML file for your EAN13 font
accordingly. This approach worked for me once. If that doesn't work
maybe you should post the XML font file to the list.

Embedding fonts is not supported yet, but the code is there and
should be in cvs next week.
