How do I create an array for user inputs of all the widths in each shape

This is my code:

What user inputs? There is no interaction with the user in that code.

Is the question about keeping a record of all of data parameters that the user enters through some mechanism not shown here? Or is the question about recording the various boundary coordinates that you have calculated? Or is the question about recording pixel arrays as if you had "painted" the shapes onto the screen and taken pictures of the results?

Start with an empty record. When a particular configuration of user inputs is ready to be recorded, recall the existing record set, add the new inputs on to it, and save that away. When you are ready, fetch the complete record and do whatever with it.
