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.
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.
Functions
func DefaultAuthScopes
func DefaultAuthScopes() []stringDefaultAuthScopes reports the default set of authentication scopes to use with this package.
ImageAnnotatorCallOptions
type ImageAnnotatorCallOptions struct {
BatchAnnotateImages []gax.CallOption
}ImageAnnotatorCallOptions contains the retry settings for each method of ImageAnnotatorClient.
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
}
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
}
func (*ImageAnnotatorClient) Close
func (c *ImageAnnotatorClient) Close() errorClose 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.ClientConnConnection returns a connection to the API service.
