PNG TrayIcon transparency on Windows

Question

I'm trying to use a transparent PNG as the icon for my Java application. The image on the JFrame and task bar work great. However, when I use the image with a TrayIcon, I get a black matte background around the edge of the PNG.

Has anybody else come across this issue? I would really like to use a PNG instead of GIF or JPEG.

With Java6, a PNG picture should be used for TrayIcon, but as mentioned in this SO question, check:

the background color chosen to represent the transparent pixels
the transparency options
the resolution of the icon
alternate format like SVG (provided you are using external library like Batik, and conversion mechnism to java.awt.Image)

The `TrayIcon` constructor takes an image. Are you sure that Java can create an image from an SVG file? – Mot Aug 10 '10 at 11:34
@mklhmnn You are right, but with a Java library like Batik , you can create an Image from a SVG file. See also thread http://markmail.org/message/pfcceqjgy2mxvy6m – VonC Aug 10 '10 at 14:23
@mklhmnn: not tested. And the OP didn't return to give us any feedback. Do you have any new element to add to this issue? – VonC Aug 10 '10 at 18:18
