常用示例
Show codestream header information
jxlinfo [path/to/image.jxl]
Verbose output
jxlinfo -v [path/to/image.jxl]
Inspect multiple files
jxlinfo [image1.jxl] [image2.jxl] [image3.jxl]
Display help
jxlinfo -h
说明
jxlinfo prints information about JPEG XL (.jxl) image files by parsing the codestream header without performing a full decode. It reports image dimensions, bit depth, color encoding (including ICC profile presence), animation properties, and container box structure. The tool is part of libjxl-tools, the reference implementation distribution for JPEG XL maintained by the JPEG XL Project. It is commonly used to verify that a file is a valid JPEG XL codestream, to inspect encoding parameters before decoding, and to debug encoder output. In verbose mode, jxlinfo prints additional details such as frame headers, extra channels, animation timing, and intensity target. The non-verbose mode is suitable for scripting where a brief summary is needed.

- Produce more verbose output, including detailed bitstream and frame information.
- -h, --help, -?
- Display the help message listing all available options and exit.
- _INPUT_
- One or more input JPEG XL image filenames to inspect.

How do I run a basic jxlinfo example?
Run `jxlinfo [path/to/image.jxl]` in a terminal, then adjust file names, paths, flags, or remote targets for your system.
What does -v, --verbose do in jxlinfo?
Produce more verbose output, including detailed bitstream and frame information.
