Call decreaseRed on the rest of the pixels. Call it like: This actually won’t work for reasonable-sized pictures—takes up too much memory in Java. decreaseRed( getPixels(pic)) Recursion can be hard to get your head around It really relies on you trusting your functions. They’ll do ...
However the output response from the functions (e.g.get_image_positions()) will be only printed below the cell where the function is executed, and it would not be possible to assign the output to the variable. (After the cell is executed on Shift-Enter, the global variable_results_pyppt...
