optimized-hd2sd

A Rust application designed to process osu skin HD textures and create optimized SD textures.

Features

• Recursively finds all HD textures (denoted with @2x in file name) in the selected directory and its subdirectories.
• Creates new SD textures using Catmull-Rom filtering for high-quality downscaling.
• Losslessly optimizes both input (HD) and output (SD) file sizes using oxipng.
• Processes images in batches for improved performance.
• Provides options to preserve existing SD images and customize batch size.

Usage

GUI

1. Run the executable.
2. Select the directory containing the skin files when prompted.
3. The application will process all @2x images in the selected directory and its subdirectories.

• -b, --batch-size <SIZE>: Set the batch size for processing images (default:20)
• -p, --preserve: Preserve existing SD images
• -h, --help: Display help information
