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 leafís 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 Iíveused, but Iíd like students in my biology class to do this on their iPad ifthey can, since they will all have those. I didnít see an ImageJ iPad app."
