{"success":true,"data":{"ext":"jpg2","name":"JPG2","description":"JPEG 2000 is an image format standard developed by the Joint Photographic Experts Group and standardized by ISO/IEC and ITU-T. It is used for still images in digital archiving, medical imaging, geospatial systems, and other workflows that require lossless or high-quality lossy compression. The format is mature and generally safe to open, though support is less common than for baseline JPEG and some legacy files may require specialized software.","mime":[],"risk_level":"Safe","signatures":[{"hex":"00 00 00 0C 6A 50 20 20 0D 0A 87 0A","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":["j2k","jp2","jpc","jpf","jpgm","jpm"],"usage":{"python":"def is_jpg2(file_path: str) -> bool:\n    \"\"\"Check if file is a valid JPG2 by magic bytes.\"\"\"\n    signature = bytes([0x00, 0x00, 0x00, 0x0C, 0x6A, 0x50, 0x20, 0x20, 0x0D, 0x0A, 0x87, 0x0A])\n    with open(file_path, \"rb\") as f:\n        return f.read(12) == signature","node":"function isJPG2(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x00, 0x00, 0x00, 0x0C, 0x6A, 0x50, 0x20, 0x20, 0x0D, 0x0A, 0x87, 0x0A]);\n  return buffer.subarray(0, 12).equals(signature);\n}","go":"func IsJPG2(data []byte) bool {\n    signature := []byte{0x00, 0x00, 0x00, 0x0C, 0x6A, 0x50, 0x20, 0x20, 0x0D, 0x0A, 0x87, 0x0A}\n    if len(data) < 12 {\n        return false\n    }\n    return bytes.Equal(data[:12], signature)\n}"},"category":"Images"}}
