Poster with Python

Poster with Python

I created a poster using the knowledge shared in the course.

To create my poster I used Python 3.13 running on VS Code IDE installed in a Linux Ubuntu OS.

import py5
from random import randint, seed

save_document = False # Variable to control saving the document
s = 1 # Seed for random number generator

# Initializes the sketch window and sets up the drawing environment.
def setup():
py5.size(693, 980)

def draw():
global s, save_document
py5.begin_record(py5.PDF, f'output/poster_4_2_{s}.pdf')
seed(s)
py5.background(70, 70, 0)
for _ in range(3):
grid(4, 6, 50, 40, 600)
py5.end_record()
if s == 20:
py5.exit_sketch()
s += 1 # Increment seed for next draw

def grid(cols, rows, offset_x, offset_y, wt):
py5.stroke(255)
# cols is number of columns
# rows is number of rows
# offset_x is the margin from the left and right edges
w = wt / cols
for j in range(rows):
y = j * w + w/2 + offset_y
r = randint(0, 128)
g = randint(0, 255)
b = randint(0, 255)
py5.fill(r, g, b)
for i in range(cols):
x = i * w + w/2 + offset_x
m = randint(1, 6)
if m <= 2:
concentric_circles(x, y, randint(1,4), w-5*randint(0,5))
elif 2 < m <= 5:
py5.fill(randint(0, 128), 150)
dr = randint(0, 1)*w/2
py5.rect(x-dr, y-dr, w/2, w/2)
else:
py5.fill(randint(0, 128), randint(0, 128), randint(0, 150), 150)
ra = randint(5, int(w/2))
rb = randint(5, int(w/2))
np = randint(4, 10)
star(x, y, ra, rb, np)
if randint(1, 3) == 3 and w > 30:
grid(2, 2, x-w/2, y-w/2, w)

def concentric_circles(x, y, n, d):
# Draws n concentric circles centered at (x, y) with a maximum diameter d.
py5.stroke(0)
for i in range(n):
py5.fill(randint(0, 128), randint(0, 128), randint(0, 150), 150)
py5.circle(x, y, d - i * d/n)

def star(cx, cy, ra, rb, np, angle=0):
step = py5.TWO_PI / np
py5.begin_shape()
for i in range(np):
a = angle + i * step
ax = cx + py5.cos(a) * ra
ay = cy + py5.sin(a) * ra
py5.vertex(ax, ay)
bx = cx + py5.cos(a + step/2) * rb
by = cy + py5.sin(a + step/2) * rb
py5.vertex(bx, by)
py5.end_shape(py5.CLOSE)

def mouse_pressed():
global s
s += 1
print(s)
py5.redraw() # Redraw the canvas on mouse press

def key_pressed():
global save_document
if py5.key == 's':
py5.save_frame(f'drawing_u4_v1_seed_{s}.png')
elif py5.key == 'p':
save_document = True
print('Saving document...')

py5.run_sketch() # Run the sketch to see the setup and draws applied.
