Design using SVG's
SVG's(Scalable Vector Graphics) are very powerful in designs because of the scalability. Any existing logo or image can be converted to a .svg and as I recently discovered, there are very cool svg libraries available in python.
Create a SVG using Python code
The majority of this code was generated in copilot and I played around with the parameters until I managed to get what I wanted to see in the svg.
- create_sundial_svg.py
import svgwrite from math import cos, sin, pi def create_custom_sundial_face(): # Create an SVG drawing dwg = svgwrite.Drawing('custom_sundial_face.svg', profile='tiny', size=(500, 500)) # Center of the sundial center_x = 250 center_y = 250 radius = 160 # Draw the outer circle with a decorative border dwg.add(dwg.circle(center=(center_x, center_y), r=radius, stroke='black', fill='none', stroke_width=5)) # Function to draw lines def draw_line(angle, length, color='black', stroke_width=1): x1 = center_x + radius * (1 - length) * cos(angle) y1 = center_y + radius * (1 - length) * sin(angle) x2 = center_x + radius * cos(angle) y2 = center_y + radius * sin(angle) dwg.add(dwg.line(start=(x1, y1), end=(x2, y2), stroke=color, stroke_width=stroke_width)) # Function to draw text def draw_text(angle, text, radius_offset=10): x = center_x + (radius + radius_offset) * cos(angle) y = center_y + (radius + radius_offset) * sin(angle) + 0 # Adjust y coordinate for vertical alignment rotation_angle = angle * 180 / pi + 90 # Convert radians to degrees and adjust for vertical alignment #dwg.add(dwg.text(text, insert=(x, y), text_anchor="middle", font_size="12px", font_family="Roman")) dwg.add(dwg.text(text, insert=(x, y), text_anchor="middle", font_size="12px", font_family="Verdana", font_weight='bold', transform=f"rotate({rotation_angle},{x},{y})")) # Draw 5-minute lines for five_minute in range(288): if five_minute % 12 == 0: continue angle = (five_minute / 288) * 2 * pi - pi / 2 draw_line(angle, 0.05)#, color='purple') # Draw 15-minute lines for quarter_hour in range(96): if quarter_hour % 4 == 0: continue angle = (quarter_hour / 96) * 2 * pi - pi / 2 draw_line(angle, 0.08)#, color='red') # Draw half-hour lines for half_hour in range(48): if half_hour % 2 == 0: continue angle = (half_hour / 48) * 2 * pi - pi / 2 draw_line(angle, 0.10)#, color='green') # Draw hour lines and Roman numerals with custom colors for hour in range(24): angle = (hour / 24) * 2 * pi - pi / 2 draw_line(angle, 0.15, stroke_width=2)#, color='blue') roman_numeral = ["XII", "I", "II", "III", "IIII", "V", "VI", "VII", "VIII", "IX", "X", "XI"][hour % 12] if hour >= 12: roman_numeral #+= " PM" else: roman_numeral #+= " AM" draw_text(angle, roman_numeral) # Save the SVG file dwg.save() # Create the custom sundial face SVG create_custom_sundial_face() print("The custom sundial face SVG has been created and saved as 'custom_sundial_face.svg'.")
The result of the above code looks like this.
