ROI and color assigning

[sree99]

Hello all

I got a 'image editor' VI from forum that performs various color assignments (RGB) to the single image on different combinations.

 I want to modify it in such a way that I can  select a certain portion(ROI) and

assign a combination(eg;RG) on that part and select another ROI and assign a diffrent combination (RB) etc...

In final output image should contain an image with different RGB combinations on selected parts.

Thanks in advance
