Dear ImageJ users,

I want to do simple masking and then subtract (or may be blacken) certain parts of an image using a black and white masking image . both original and masking images have the same size but the masking image describe the areas I need for working on my main picture.

I don't know which commands I can use with imageJ since I want to do them using java codes.

Thanks for any hint,
Regards
