The evaluation version of Aspose.BarCode for Python via Java allows full barcode generation functionality but adds a watermark (“Aspose”) to each generated image. It also supports barcode recognition for all types; however, only Code 39 can be fully decoded. For all other symbologies, 30% of the recognized text will be replaced with asterisks ("*").
Any additional functionality—such as saving clean images, full barcode decoding, and advanced settings—requires applying a valid license.
Once a license is applied, all limitations are removed, including watermarking and masked output, unlocking full access to barcode generation and recognition capabilities.
To evaluate the full version without restrictions, you can request a 30-day temporary license.
