Render partly transparent SVG image for GEF FreeformLayer [message #248921]

Hi, I would like to display an SVG image as a background in my GEF editor.
I have subclassed the FreeformLayer so that it accepts and displays an SWT
Image, much like the ImageFigure. I render the Image with an
SVGImageConverter.

Everything works fine until I try out SVG documents that include
transparency. An UnsupportedOperationException is thrown, because SWT
doesn't support transparency.

But actually, I don't need the resulting image itself to be transparent. I
just want to render the SVG correctly against a white background. What
classes can I use (SVGImageConverter is internal anyway), and how do I
have to configure them to render a transparent SVG image?

Regards,
Gerrit
