| // Package vision is an auto-generated package for the |
| // Cloud Vision API. |
| // |
| // Integrates Google Vision features, including image labeling, face, logo, |
| // and landmark detection, optical character recognition (OCR), and detection |
| // of explicit content, into applications. |
| // |
| // NOTE: This package is in beta. It is not stable, and may be subject to changes. |
| // |
| // Use of Context |
| // |
| // The ctx passed to NewClient is used for authentication requests and |
| // for creating the underlying connection, but is not used for subsequent calls. |
| // Individual methods on the client use the ctx given to them. |
| // |
| // To close the open connection, use the Close() method. |
| // |
| // For information about setting deadlines, reusing contexts, and more |
| // please visit pkg.go.dev/cloud.google.com/go. |
