Hi khan
I do not know how to make macros in ImageJ... yet, but I've calculated the white area percentage with this program. I'understood you want to calculate that. You don't need to set scale because you can make the percentage whith pixels. the whole area of the image is in the image information. To obtain the white area you have to use the threshold. Select the area and then apply measurement. The percentage is 100*white area in pix^2/total area in pix^2. I hope it helps you
