Overview ¶
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 godoc.org/cloud.google.com/go.

Functions ¶
func DefaultAuthScopes ¶
func DefaultAuthScopes() []string
DefaultAuthScopes reports the default set of authentication scopes to use with this package.
Types ¶
type ImageAnnotatorCallOptions ¶
type ImageAnnotatorCallOptions struct {
BatchAnnotateImages []gax.CallOption
}
ImageAnnotatorCallOptions contains the retry settings for each method of ImageAnnotatorClient.
type ImageAnnotatorClient ¶
type ImageAnnotatorClient struct {
// The call options for this service.
CallOptions *ImageAnnotatorCallOptions
// contains filtered or unexported fields
}
ImageAnnotatorClient is a client for interacting with Cloud Vision API.
Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
func NewImageAnnotatorClient ¶
func NewImageAnnotatorClient(ctx context.Context, opts ...option.ClientOption) (*ImageAnnotatorClient, error)
NewImageAnnotatorClient creates a new image annotator client.
Service that performs Google Cloud Vision API detection tasks over client images, such as face, landmark, logo, label, and text detection. The ImageAnnotator service returns detected entities from the images.
Example ¶
package main
import (
"context"
vision "cloud.google.com/go/vision/apiv1p1beta1"
)
func main() {
ctx := context.Background()
c, err := vision.NewImageAnnotatorClient(ctx)
if err != nil {
// TODO: Handle error.
}
// TODO: Use client.
_ = c
}
Output:
func (*ImageAnnotatorClient) BatchAnnotateImages ¶
func (c *ImageAnnotatorClient) BatchAnnotateImages(ctx context.Context, req *visionpb.BatchAnnotateImagesRequest, opts ...gax.CallOption) (*visionpb.BatchAnnotateImagesResponse, error)
BatchAnnotateImages run image detection and annotation for a batch of images.
Example ¶
package main
import (
"context"
vision "cloud.google.com/go/vision/apiv1p1beta1"
visionpb "google.golang.org/genproto/googleapis/cloud/vision/v1p1beta1"
)
func main() {
// import visionpb "google.golang.org/genproto/googleapis/cloud/vision/v1p1beta1"
ctx := context.Background()
c, err := vision.NewImageAnnotatorClient(ctx)
if err != nil {
// TODO: Handle error.
}
req := &visionpb.BatchAnnotateImagesRequest{
// TODO: Fill request struct fields.
}
resp, err := c.BatchAnnotateImages(ctx, req)
if err != nil {
// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
}
Output:
func (*ImageAnnotatorClient) Close ¶
func (c *ImageAnnotatorClient) Close() error
Close closes the connection to the API service. The user should invoke this when the client is no longer required.
func (*ImageAnnotatorClient) Connection ¶
func (c *ImageAnnotatorClient) Connection() *grpc.ClientConn
Connection returns a connection to the API service.
Deprecated.
