PDFTranscoder and font-stretch attribute

[Petar <op...@yahoo.com>]

Hello,

I was trying to use "font-stretch" attribute in my SVG which I wanted to
convert to PDF using PDFTranscoder.  I ran into some problems.

I first added the proper font element to my configuration file.  However, the
transcoder didn't use it as expected.  It ignored my stretch attribute.  It
turns out, FOP does not support this attribute for font lookups.  It only uses
family, weight, and style.  These seem to be consistent with CSS1 but not with
CSS2.  CSS2 has added font-stretch attribute and font-variant.

Is there a plan to support these additional attributes?  Is seems that for
PDFTranscoder the changes will be needed in:
fop.apps.Document
fop.render.pdf.FontSetup
fop.svg.PDFTextPainter

Of course, other renderes besides PDFTranscoder would need to be changed as
well but it could be possible to keep backwards compatibility.

Is this something that is in plans?  If not, would you accept potential
contributions?

Thanks,
Petar

Sure, just send patches. I think there are no immediate plans. The PDF
transcoder has a pretty good feature set (thanks to Keiron Liddle
in particular) but it is certainly not complete. So we're happy to add
your contributions. Just be patient with us for applying the patches as
we're undermanned in this project. If we don't respond just poke again.

Yup! font-stretch currently not implemented
(see: http://xml.apache.org/fop/compliance.html#fo-property-font-stretch )

Yes, and so has XSL-FO. Only basic conformance level does not require a
processor to support this property.

Always! But keep in mind that patches for 0.20.5 have less priority for the
moment, so *if* you decide to enter a few patches, be sure to also include
them for the Development Codebase (If I'm not mistaken, the PDFTranscoder is
the same in both versions, but I'm not sure about the other affected
classes...)


Cheerz,
