- Implemented purely in PHP, no external dependencies except GD2
- Exports to PNG, JPEG images, also exports as bit-table
- TCPDF 2-D barcode API integration
- Easy to configure
- Data cache for calculation speed-up
- Provided merge tool helps deploy library as a one big dependency-less file, simple to “include and do not wory”
- Debug data dump, error logging, time benchmarking
