drawille-canvas provides HTML5 Canvas API for drawille.
api
Canvas(w, h)
Create a new canvas with the given dimensions.
w must be multiple of 2, h must be multiple of 4.
Uses columns & rows from process.stdout as default values for w and h.
canvas.set(x, y)
Draw point on canvas at the given position.
canvas.unset(x, y)
Delete point on canvas at the given position.
canvas.toggle(x, y)
Toggle point on canvas at the given position.
canvas.clear()
Clear the whole canvas (delete every point).
canvas.frame(delimiter)
return the current content of canvas, as a delimiter-delimited
string. delimiter defaults to \n.
it uses braille characters to represent points,
so every line has length of w/2, and the string contains h/4
lines.
