Thanks for the reply Pyrochild,
I have downloaded the set of plugins and trying them, fabulous work there. However, making a BMP image with specifically the colors I need (black, white and red) doesn't seem to be there or I am not looking and trying them correctly. Your image of trump look like the three colors I need but it is all kind of red and white. I need only 'pure' red (255), pure white and pure black. how can it be done?
Thx a lot
