I'm using some python scripts to process images. An image is some between 500x500 or 4000x4000 pixels. The scripts do iterations over every pixel, so they're time consuming, so I set up the multiprocessor function. There's something I can't find any documentation on.. so, if I have the script iterate through with Pool.map one pixel at a time height-wise, it appends a dimension to the returned array. I would usually have a returned array height, width, # of color channels, but the mp functions would return a list instead of an array that is height, height, width, # of color channels, 1 extra channel for every iteration. OK.. so the child processes put their data into their own slice of memory space, which is fine.. but what exactly are the details? I can't find it, should I just take the last number on the stack? take an array that is now height, 0:height, 0:width, 0:channel count, and reshape it to the array size I would have gotten as usual? Or is it the 1st one? I can't find this information
