name: geometric-elements
description: Generate decorative geometric elements (corners, lines, arcs, frames) with precise control over colors, gradients, and transparency. Use when creating design assets, slide decorations, or any vector-like graphics programmatically. Can also analyze reference images and recreate geometric patterns.

Geometric Elements Generator

Create decorative geometric elements with code using Pixie-python.

Quick Start

# Install dependency (first time only)
pip install pixie-python

# Generate element (ask user for brand color or check their brand guidelines)
python .claude/skills/geometric-elements/scripts/generate.py corner-accent \
  --color "#HEX_COLOR" \
  --size 200 \
  --output media/output/corner.png

Important: Always ask user for brand colors or check their brand guidelines skill (e.g., /thepexcel-brand-guidelines) before generating.

Available Elements

Common Options

Examples

Basic Shapes

# Circle (stroke)
python scripts/generate.py shape --style circle --color "#HEX" --size 100 --stroke 3

# Star (filled)
python scripts/generate.py shape --style star --color "#HEX" --size 100 --sides 5 --fill

# Available: circle, ellipse, rectangle, square, rounded-rect, triangle,
#   polygon, star, diamond, ring, cross, arrow, heart, hexagon, octagon, crescent

Corner Accent

python scripts/generate.py corner-accent --color "#HEX" --size 150 --stroke 4

Gradient Line Divider

python scripts/generate.py line-divider --color "#HEX" --color2 "#FFFFFF" --gradient linear --width 800

Mandala (Sacred Geometry)

python scripts/generate.py mandala --color "#CCC" --bg "#0A0A0A" --size 400 --rings 8 --layers 4 --stroke 1.5

Custom Elements (On-the-fly)

For complex patterns not in predefined commands, write Python directly:

import pixie
import math

image = pixie.Image(400, 400)
paint = pixie.Paint(pixie.SOLID_PAINT)
paint.color = pixie.Color(0.83, 0.66, 0.29, 1.0)  # RGB 0-1 range

ctx = image.new_context()
ctx.stroke_style = paint
ctx.line_width = 2
ctx.stroke_segment(50, 50, 350, 350)

image.write_file("output.png")

From Reference Image

User can send reference images for Claude to analyze and recreate:

1. User sends image — screenshot, design reference, pattern
2. Claude analyzes — identifies shapes, colors, proportions
3. Claude writes code — using pixie-python API
4. Output — PNG ready to use

Tips for good reference: Clear image, geometric patterns (not photos), specify hex colors if needed.

Tips

1. Transparent bg — All outputs have transparent background by default
2. High DPI — Use --size 2x for retina displays
3. Gradients — Combine --gradient linear with --color and --color2
4. Brand colors — Always confirm with user or their brand guidelines first
