vhybZ OS Logo

This project aims to create our "propeller" logo image using the drawsvg Python library.

Project Structure

• main.py: The main script to generate the SVG drawing. It sets up the canvas, arranges the different parts of the logo, applies styles (colors, opacity, filters), and saves the output.
• petal.py: Contains functions for drawing the individual "petal" or "blade" shapes that make up the logo's structure.
• README.md: This file, explaining the project.
• robot.md: Provides detailed context and instructions for an AI assistant to continue working on the project.

Approach (v0.1)

The logo is visually composed of four overlapping, translucent, colored petal shapes arranged in an 'X'. This initial version implements this interpretation:

1. Petal Shape: A single, abstract petal shape is defined in petal.py using a drawsvg.Path element with cubic Bézier curves. It's drawn with its base at the origin (0,0) and tip along the positive y-axis for easy rotation.
2. Composition: In main.py, the draw_single_petal function is used to create the base shape. This shape is then included in a drawsvg.Group which applies a global scale to make the petal a reasonable size. This scaled shape definition is then referenced four times using drawsvg.Use.
3. Arrangement: Each drawsvg.Use element is rotated around the center of the drawing to form the 'X' shape.
4. Color and Blending: Each petal Use element is given a distinct fill color and a fill_opacity less than 1.0 to create the overlapping color blending effect seen in the original image.
5. Shadow: A basic SVG drop shadow filter is defined in main.py using drawsvg.Filter and feGaussianBlur/feOffset/feMerge. This filter is applied to the bottom two petals to simulate the shadow.
6. Background: A simple colored rectangle is added as the background.

Getting Started

1. Install drawsvg (and optional rasterization dependencies if needed):

   python3 -m pip install "drawsvg[all]~=2.0"

   You might also need to install Cairo separately depending on your OS (see drawsvg documentation for details).
2. Save the code above into petal.py and main.py in a drawsvg_logo directory.
3. Run main.py from your terminal:

   cd drawsvg_logo
   python main.py

   This will generate logo_v0_1.svg in the same directory.

Next Steps

• Refine Petal Shape: The Bézier control points in petal.py need tuning to precisely match the curves of the original image's petals.
• Refine Colors/Gradients: The current implementation uses solid colors with opacity for simplicity. The original image shows subtle gradients within each petal. These should be added.
• Refine Shadow: Adjust the filter parameters (blur amount, offset) and potentially opacity/color of the shadow effect to better match the original.
• Implement Texture: Investigate methods to add the subtle grainy texture, possibly using SVG filters (feTurbulence) or other techniques.

This initial version provides the structural foundation for recreating the logo.
