Symbol Transparency

Hello,
Does anyone know if it is possible to make symbology and/or overlay tiles transparent using the j2me library? Any ideas or suggestions would be welcome.
Paul.

Thank you very much for the reply. I amended the alpha channel on the fly using getRGB(), drawRGB etc. and it seems to have all worked out.

You need to define alpha channel for PNG files using some imaging tools (e.g. GIMP or something) and then you can use them as either marker icons or semitransparent overlay tiles. Some (or maybe most) map servers enable to have transparent background for the map tiles (images). MGMaps Library itself has no image manipulation tools for modifying images.
