Icon or Image Flashing Style in P300

[jsuwicha]

I'm trying to use icons or images (.bmp) instead of alphabets in P300. However, I want the icons flash like alphabet's style or icons in web browser application (http://www.youtube.com/watch?v=GuuhQur7Tjk). During flashing, the icons should be hightlighted or intensified. I attempted many ways by making icon's background transparent and setting its ColorIntensified to be white but the icon still be black during flash (black in the whole icon). I also looked at TextStimulus.cpp and ImageStimulus.cpp but still no clue. Do I need to set value of RenderingMode parameter? What is the default value (transparent or opique) in binary version?

Please direct me to the link explained how to set P300's parameters or how to create icon .bmp picture in order to solve this problem.

Thank you very much
