How does it work?

  1. The image is normalized for brightness and transformed to grayscale. See canvasDataToGrayscale. I try to make the lightest zone white, and the darkest black.
  2. A point in the canvas is selected at random and a line starts looking for different paths to draw next. At each step, the pencil draws imaginary lines to different points of the image and asks itself which one of those points would make the drawing look more like the original image, then it picks that one, draws the line and moves the cursor. The amount of imaginary lines is controlled by the "definition" slider. More lines mean more precise (but less terrifying) images. See scan functions
  3. Lines are batched to be drawn and get flushed almost every frame.
  4. Results are exported as svg as a very simple polyline, see generateSvg. PNG export is taken directly from the canvas.

Pixel data and resizing were made using canvas-image-utils, better face definition using face-api.
