So we have an app that will take any given bmp and calculate the area occupied but the object in view? Provided it has a black background?
Couple of questions, is it just counting the non black areas? So a motif might be half color half black what gets counted?
Also most objects are 3D so how do we handle that.
Not really sure I understand what the app can be used for. Interesting but the practical use example might explain all.

Ah well no so, no black in the object, that would be considered as a hole !.
This software can be used by someone who wants to measure the rate of degradation of a paper or a fabric or simply to give surfaces difficult to calculate by geometry.
There are almost as many explanations as there are code. Lol!

I helped some students code something like this, where they were studying changes in size of leaves. Constrained between two glass sheets and camera in fixed position. In those days I had an analogue signal from a video camera and a video digitiser- but it did the job well.
This is a neat use of LB.
I had earlier used memory chips as a form of digital camera- you cracked off the cover and light affected the memory cells. Read by Acorn BBC computer. And in 1964/5 I worked as a lab assistant on a company developing similar technology for fast analysis of metals- steel for ferrite/pearlite, brasses for grain size.
