LineDream 0.2.0

A creative coding library...

LineDream is a generative art library for Python. It is heavily influenced by P5 and Processing. However, it takes a more object oriented approach, with less global state in regards to styling and transformations.

The current output target is SVG. As this provides a robust output set for vector graphics. There is not yet support for a draw loop - it is single frame output, but you could use a loop to simulate this. There are future plans to implement an OpenGL render window.

LineDream library was originally created to make art for a pen plotter, however, the inner object structure could be applied to many different rendering platforms.

Installation

pip install LineDream

Example

import random
from LineDream import Line, Canvas, Rectangle, Square, Ellipse, Point, Circle, CircleMath, TextLine

Canvas.width=900
Canvas.height=500
Canvas.background_color='black'

for pp in range(100):
	x = random.randint(0, Canvas.width)
	y = random.randint(0, 400)

	coords = (x,y)
	p = Point(*coords)

	p.stroke_color= 'white'

c_size = 180

circle_center = Canvas.width/2, Canvas.height+c_size/2
c = Circle(*circle_center, 180)
c.stroke_color='white'

c = Circle(*circle_center, 200)
c.stroke_color='white'

c = Circle(*circle_center, 220)
c.stroke_color='white'

long=True
for degrees in range(360,180,-10):

	dist_from_circle = 250

	line_len = 40
	if long:
		line_len = 100
		long=False
	else:
		long=True

	d_x_s, d_y_s = CircleMath.distance_to_coords(degrees, dist_from_circle)
	x1 = circle_center[0] + d_x_s
	y1 = circle_center[1] + d_y_s

	d_x, d_y = CircleMath.distance_to_coords(degrees, dist_from_circle + line_len)
	x2 = circle_center[0] + d_x
	y2 = circle_center[1] + d_y

	Line([(x1,y1), (x2,y2)], stroke_color='white')

# EXPERIMENTAL
tt = TextLine('LineDream', kerning=10, stroke_color='white', stroke_width=2)
tt.transform(100, 100)
tt.scale(1.4)

Canvas.save(f'example.svg')

Todos:

• Test/document colors/opacity
• Document Canvas
• Integrate TextPath with Hershey (initial implementation complete)
• Convert all vertexes to Numpy arrays
• Add .scale() (partially implemented in some classes)
• Add 'tag' notion
• Add PathGroup()

Internal

To push to PyPI run:
