Hi all,

new to imageJ (and no coding/macro experience) and have some questions about image J's potential for shape analysis.

1/ Is there any way to batch convert colour images to B & W so that i would have a white image on a black background or vice versa?

2/ When i analyse an image, how do i set it so the measurements are of the particular shape outline (within the image) rather than the whole image outline?

3/ How do i go about selecting a shape outline to measure? Again is there any way to batch measure multiple images with shape outlines or images with white shapes on black background?

thank you in advance!

Craig.
