[xep-support] Problem with SVG opacity support in PDF

Hello all,


I have the following problem with the correct rendering of an SVG image
within PDF. The image itself has been created using Adobe Illustrator
and is correctly displayed in another SVG editor, Inkscape in this case.
When inserted into an XSL-FO file and transformed by XEP, it is not
rendered correctly. That is, the part of the image that has a linear
gradient layer on opacity is rendered as a black circle.

For your reference, I am attaching the sample files:

* XEP_PDFview.png - this is how the resulting PDF is displayed
in Adobe Reader.

* SVGview.png - this is how the image is displayed in Inkscape
or Adobe Illustrator.

* XEP_PDFpage.pdf - the page extracted from a PDF created by

* opacityTest.svg - the SVG image used in this experiment.


According to XEP documentation, opacity and gradients are supported by
XEP 4.19 (build 20110414) used to generate the PDF file (version 1.4).
Note that the attached PDF is an extract from the original one.


Is there a setting in XEP configuration (or maybe in SVG?) that allows
for correct rendering that kind of combination of gradients and opacity?
