Licensing

Overview

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.

How to Obtain a License

To evaluate the full version without restrictions, you can request a 30-day temporary license.
More information is available here: How to get a Temporary License?

For production use, a commercial license is required. License pricing and details are available at:

Every license includes:

• 1-year subscription: Access to all updates and bug fixes during the subscription period.
• Free technical support: Available to both licensed and evaluation users without limitations.

License File

The license is an XML file that contains essential information about your license, including:

• License Type
• Order ID
• Product Names the license applies to
• Customer details
• Edition Type
• Serial Number

A trial license includes an additional field, LicenseExpiry, which specifies the expiration date. After this date, the trial license becomes inactive.

Both trial and commercial licenses include a SubscriptionExpiry field, which defines the period during which you are entitled to receive product updates, such as:

• Bug fixes
• Performance enhancements
• New feature additions

⚠️ Note: Typically, the LicenseExpiry date is earlier than the SubscriptionExpiry.
Therefore, for trial licenses, the SubscriptionExpiry has no practical effect.

⚠️ Do not modify the license file.
The license is digitally signed. Any changes — including additional spaces or line breaks — will corrupt the file and cause validation to fail.
