Getting Rid of the Watermark - Get a License

Out of the box - unidoc is unlicensed and outputs a watermark on all pages, perfect for prototyping. To use unidoc in your projects, you need to get a license. We have 3 license types:

• Community: For open source AGPLv3 projects
• Business Individual
• Business Unlimited

Get your license on https://unidoc.io.

To load your license, simply do:

unidocLicenseKey := "... your license here ..."
err := license.SetLicenseKey(unidocLicenseKey)
if err != nil {
    fmt.Printf("Error loading license: %v\n", err)
    os.Exit(1)
}

Examples

Multiple examples are provided in our example repository. Many features for processing PDF files with documented examples on our website.

Licensing Information

This library (UniDoc) has a dual license, a commercial one suitable for closed source projects and an AGPL license that can be used in open source software.

Depending on your needs, you must choose one of them and follow its policies. A detail of the policies and agreements for each license type are available in the LICENSE.COMMERCIAL and LICENSE.AGPL files.

In brief, purchasing a license is mandatory as soon as you develop activities distributing the UniDoc software inside your product or deploying it on a network without disclosing the source code of your own applications under the AGPL license. These activities include:

• offering services as an application service provider or over-network application programming interface (API)
• creating/manipulating documents for users in a web/server/cloud application
• shipping UniDoc with a closed source product

Please see pricing to purchase a commercial license or contact sales at [email protected] for more info.

Contributing

Contributors need to approve the Contributor License Agreement before any code will be reviewed. Preferably add a test case to make sure there is no regression and that the new behaviour is as expected.
