Description

JP2 (JPEG 2000 Part 1) validator and properties extractor. Jpylyzer was specifically created to check that a JP2 file really conforms to the format's specifications. Additionally jpylyzer extracts technical characteristics of a JP2 image.

See also: A prototype JP2 validator and properties extractor.

Successor to Jp2StructCheck.

User Experiences

• KOST-CECO: Used in KOST-Val for the JP2 validation module. KOST-Val translates the failed tests into appropriate error messages (DE/FR/EN).
