OFDRW is an open-source Java library for reading, writing, and manipulating OFD (Open Fixed-layout Document) files, a Chinese national standard format defined by GB/T 33190-2016. It supports document generation, digital signatures, encryption, merging, and conversion to other formats like PDF and images.
Use cases
- generate OFD documents in Java
- parse and extract text from OFD files
- add digital signatures to OFD documents
- convert OFD to PDF or images
- merge or split OFD documents
- validate OFD archive compliance
- process Chinese electronic invoices in OFD format
When to choose
- your application must create, read, or edit OFD files per the GB/T 33190-2016 standard
- you need digital signatures or GM (Chinese national cryptography) support for OFD documents
- you need to convert OFD documents to PDF or images in a JVM project
When to avoid
- you only work with PDF or other document formats and never encounter OFD
- you need a non-JVM language implementation
- you need a GUI viewer rather than a programmatic library
