ImageFilter use in OMRasterObject

I have developed a layer which displays text and an icon for points which have been selected by the user from a database. Either or
both the text and icon are displayed.

I want to allow them to pick items from the map using the mouse and I want to be able to show them which items have been selected.

I can alter the text display of selected items by using setBoundsLineCOlor.

I'd like to change the icon presentation and have been trying to do this with setImagFilter() to XOR the colours with a mask colour
(so that I can XOR them back again).

Does anyone have any hints or examples of doing this please?

regards,

Adrian
