In other words, we look at each of the pixel’s eight neighbors, filter out those that are not undrawn edge pixels, and choose the one that maximizes directionality preservation. When our robot plans its path, after we enter a pixel from a certain direction, we decide the next pixel we travel to by favoring undrawn edge pixels that are most similar to that previous direction. We can think of our commands as a list of tuples each telling us where to drag our cursor from and to. Meaning, we sketch things in smooth, continuous strokes, not jumpy or erratic scrubs. When we humans draw, we try to maintain directionality. Okay, so we know how we’re going to keep track of our edge pixels, but how do we determine the order in which we draw them? Momentum and Continuity This means that once we finish drawing an edge pixel, we remove it from both data structures. These will keep track of our undrawn edge pixels. So, we can stick all the edge pixel coordinates into a HashSet and KD Tree. We need a way to keep track of our edge pixels efficiently. Such pictures are suitable for children, beginners and everyone.

First, we construct a list of commands (discussed in the next section) consisting of points to drag the cursor towards, when to release left click, and when to hold left click.

Okay, but before we get into planning the sketch pathways, we need to go over how the heck we’re converting our code into a drawing on MS Paint. Construct a list of events consisting of pixels to drag the pencil towards, when to lift the pencil, and when to push the pencil. TLDR: Use a super convenient mouse cursor controlling library called PyAutoGui. This helps us define the translate method to abstract our implementation from the physical drawing. Also, we add define our origin we’ll be drawing from by using the variables startX and startY. This is the dimension in which we will be planning our sketch pathways (the order in which our program is going to draw in the lines).
After properly fitting the photo within our dedicated section, we use the detail parameter to shrink the photo into an image with a supposed pseudo dimension.
