I'm not sure I understand how this works unless all objects being measured are on the same surface as the reference object. Take for example, this image https:

Take for example, this image https://lh3.ggpht.com/n3-JnvRAOTqSOwD7UriOo7ooPGQ0Nf8wueiK_U6uu36kX-Bm1lgzVU8Xa2MK3b2jsTI=s0 https://lh3.ggpht.com/n3-JnvRAOTqSOwD7UriOo7ooPGQ0Nf8wueiK_U... Imagine measuring a distance vertically along the side of the window. Now imagine a second image in wich, instead of a window, there is just more of the (now larger) desk. If you were to draw the same line in the same location in the second image, the actual distance of the underlying object would be different. Does TakeMeasure somehow account for this? I would assume the answer is no, and if so that would still make for a useful app, but then I saw this "TakeMeasure allows you to measure dimensions of any small or large objects that fit into your camera view.
