Quickstart Guide

Get the points of a line from (0, 0) to (5, 10):

>>> import pybresenham
>>> for x, y in pybresenham.line(0, 0, 5, 10):
...     print('(%s, %s)' % (x, y))
...
(0, 0)
(0, 1)
(1, 2)
(1, 3)
(2, 4)
(2, 5)
(3, 6)
(3, 7)
(4, 8)
(4, 9)
(5, 10)
>>> list(pybresenham.line(0, 0, 5, 10))
[(0, 0), (0, 1), (1, 2), (1, 3), (2, 4), (2, 5), (3, 6), (3, 7), (4, 8), (4, 9), (5, 10)]

Get the points of a multiline from (0, 0) to (2, 0) to (2, 2):

>>> import pybresenham
>>> list(pybresenham.lines([(0, 0), (2, 0), (2, 2)]))
[(0, 0), (1, 0), (2, 0), (2, 1), (2, 2)]

Get the points of a circle, centered on (0, 0), with radius 3:

>>> list(pybresenham.circle(0, 0, 3))
[(0, -3), (3, 0), (0, 3), (1, -3), (3, -1), (3, 1), (-1, 3), (-3, -1), (-3, 1), (-1, -3), (1, 3), (2, -2), (2, 2), (-2, 2), (-2, -2)]

Get a quick drawing of the above circle:

>>> import pybresenham
>>> pybresenham._drawPoints(pybresenham.circle(0, 0, 3), bg=' ')
  OOO
 O   O
O     O
O     O
O     O
 O   O
  OOO

Get a quick drawing of a square and rectangle:

>>> import pybresenham
>>> list(pybresenham.square(0, 0, 4))
[(0, 0), (1, 0), (2, 0), (3, 0), (3, 1), (3, 2), (3, 3), (2, 3), (1, 3), (0, 3), (0, 2), (0, 1)]
>>> pybresenham._drawPoints(pybresenham.square(0, 0, 4), bg=' ')
OOOO
O  O
O  O
OOOO
>>> pybresenham._drawPoints(pybresenham.rectangle(0, 0, 15, 4), bg=' ')
OOOOOOOOOOOOOOO
O             O
O             O
OOOOOOOOOOOOOOO

Road Map

The following functions aren’t yet implemented:

• ellipse()

• ellipseVertices()

• arc()

• arcVertices()

• star()

• starVertices()

• hexGrid()

• hexGridVertices()

• hexGridInterior()

• bezier()

• bezierVertices()

• roundedBox()

• roundedBoxVertices()

The thickness, filled, endcap, and viewport parameters are still unimplemented. (Except for square() and rectangle(), which do implement the filled parameter.)
