It exposes four main command groups (im4m for manifests, im4p for payloads, im4r for restore info, and img4 for full Image4 files) and handles compression transparently\u2014using apple-compress on macOS and lzfse elsewhere, with an override environment variable available if needed.\n\nThe package targets developers and researchers working with Apple firmware analysis. It requires Python 3.9 or later and depends on pycryptodome, asn1, lzfse, apple-compress, pylzss, and click. The library is in Beta status but has been actively maintained since its first release, with no known security vulnerabilities.","worth_installing":"Yes, if you work with Apple firmware analysis or Image4 format manipulation. Low install friction, active maintenance, MIT license, no known vulnerabilities, and a focused feature set make it a straightforward choice. Not relevant for general Python development\u2014install only if you have a specific need to parse or work with Image4 files."},"id":"pyimg4","links":{"html":"https://skillfed.io/packages/pyimg4","md":"https://skillfed.io/packages/pyimg4.md","pypi":"https://pypi.org/project/pyimg4/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-04-01","license_spdx":null,"license_treatment":"permissive","name":"pyimg4","python_support":"supports_current","summary":"A Python library/CLI tool for parsing Apple's Image4 format."},"popularity":{"monthly_downloads":331214,"position":7520,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.8.8"}
