Badge Generator

A high-performance Go application that generates custom badges by combining icons and colors into PNG images.

Features

• Parallel Processing: Utilizes all available CPU cores for rendering and encoding
• Memory Efficient: Object pooling for RGBA buffers and palette-based PNG compression
• Batch Generation: Creates all valid combinations of icons and colors
• Single Mode: Generate individual badges on demand

Usage

Batch Mode

go run main.go

Generates all badge combinations and saves them to the images/ directory.

Single Mode

go run main.go 0_1_0_11

Generates a single badge with indices: symbol=0, border=1, color1=0, color2=11

Output: badge.png
