Hello - My name is Laura and I am a Technology Integration Specialist for a private school in Iowa. I received the following message from a high school teacher and wondered if anyone had heard of an app that could be of help to her: "I was wondering if you know of any iPad apps that allowstudents to measure the size of a particular color area on a digital image?That type of thing is used by biologists to measure things like leaf size. Youtake a photo of a leaf, for example, on a black background with a sizereference in the frame and then measure the size of the green colored area andcompare it to the size reference to measure the leafâ€™s area more exactly. Itallows for more exact measurements of the surface area of irregular shapes.There is a free program called ImageJ that runs off a Java platform that Iâ€™veused, but Iâ€™d like students in my biology class to do this on their iPad ifthey can, since they will all have those. I didnâ€™t see an ImageJ iPad app."
