API Reference

Video Generation

progressive_route_with_config

Generates an animated video showing the route being drawn progressively with full configuration control.

pub fn progressive_route_with_config(config: RouteVideoConfig) -> Result<()>

Configuration includes:

• Route scale and positioning (RouteScale)
• Colors for route, markers, text, and bars (RouteColor)
• Pace/distance display settings (PaceDistConfig)
• Lap statistics panel settings (LapDataConfig)
• File paths (FileConfig)
• Visibility flags (show_bottom_bar, show_route, show_lap_data)

Output Features:

• Animated route drawing
• Current position marker
• Real-time pace and distance overlay
• Lap statistics panel with heart rate, stride length, and pace bars

Image Generation

image_route_with_config

Generates a static image of the complete route with customizable styling.

pub fn image_route_with_config(config: RouteImageConfig) -> Result<()>

Configuration includes:

• Route scale and positioning (RouteScale)
• Route line color (RouteColor)
• File paths (FileConfig)
• Line thickness

Legacy API

Simple functions without configuration are still available:

// Video generation (simple)
pub fn progressive_route(
    route_scale: f64,
    offset_x_percent: f64,
    offset_y_percent: f64,
) -> Result<()>

// Image generation (simple)
pub fn route_image(
    route_scale: f64,
    offset_x_percent: f64,
    offset_y_percent: f64,
) -> Result<()>

Troubleshooting

OpenCV Not Found

error: failed to run custom build command for `opencv`

Solution: Make sure OpenCV is installed and environment variables are set:

# macOS
brew install opencv llvm
export LIBCLANG_PATH="/opt/homebrew/opt/llvm/lib"

# Check if OpenCV is found
pkg-config --modversion opencv4

LIBCLANG_PATH Error

couldn't find any valid shared libraries matching: ['libclang.dylib']

Solution: Set the LIBCLANG_PATH environment variable:

export LIBCLANG_PATH="/opt/homebrew/opt/llvm/lib"

Make it permanent by adding to ~/.zshrc:

echo 'export LIBCLANG_PATH="/opt/homebrew/opt/llvm/lib"' >> ~/.zshrc
source ~/.zshrc

FIT File Not Found

ERROR: field size: 1 is not a multiple of the base type

Solution: Ensure your FIT file is in the source/ directory and is a valid FIT file format.

Performance

Typical performance metrics:

• Processing ~5000 GPS points: ~12 seconds
• Video encoding: Real-time (30 FPS)
• Image generation: <1 second
• Memory usage: ~100-200 MB

Module Overview

• configs: Configuration types for customizing output
• generators: Core functions for video and image generation
• types: Data structures for FIT data and drawing
• utils: Helper utilities for file I/O, conversion, and rendering
