Technical Poster Generator

Approach

Use Python with Pillow (PIL) to draw an exploded-view diagram. Each hardware layer is rendered as a rounded rectangle or shaped polygon, vertically offset to create the "exploded" separation effect.

Exploded-View Construction

Layer Stack (top to bottom, with vertical gaps)

1. Outer Casing — largest footprint, rounded corners, dark fill
2. Thermal Management Unit — slightly inset, distinct accent color
3. PCB (Printed Circuit Board) — inset further, with circuit-trace detail hints
4. Battery Pack — compact rectangle, neutral/dark fill
5. Interface / Connector Board — smallest, with highlighted connector points

Drawing Strategy

• Canvas: 2400×3200px (portrait, print-quality at 300 DPI ≈ 8×10.7 inches)
• Each layer: rounded rectangle with 2-4px border
• Vertical gap between layers: 60-80px to show separation
• Slight horizontal offset or perspective shift (optional) for depth
• Annotation leader lines: thin horizontal lines from layer edge to text labels

Annotation Pattern

• Draw a thin line (1.5px) from the layer's right edge to a text label
• Use small dots at the line origin on the layer
• Label text: component name + brief spec (e.g., "PCB — 6-Layer FR4")

Title Block

• Position: top-left corner, with generous padding
• Large bold text for product name
• Smaller subtitle line below (e.g., "Technical Exploded View")

Python Libraries

• PIL / Pillow for rendering
• PIL.ImageDraw for shapes and lines
• PIL.ImageFont for typography (use truetype fonts when available)

Code Pattern

from PIL import Image, ImageDraw, ImageFont

img = Image.new('RGB', (2400, 3200), background_color)
draw = ImageDraw.Draw(img)

# Draw layers bottom-up so upper layers visually overlap if needed
for layer in reversed(layers):
    draw.rounded_rectangle(layer.bbox, radius=12, fill=layer.color, outline=layer.border)

# Add annotation lines and labels
# Save
img.save('output.png', quality=95)
