Hi,Basically i am trying to apply a mask to an bitmap RGB image and then carry out a FFT on the image.It works on the whole 300x300 image but the masked area is adding towards the generated image - i believe! So can a FFT be applied to a masked area that is non-square??If so how?John Pierson Lv 8.20 Masked image, mask and VI attatched.nb, images have been converted to jpeg as .bmp is not alowed as an attachment.
