Auto-generated vision v1 clients

This package includes auto-generated clients for the vision v1 API.

Use the handwritten client (in the parent directory, cloud.google.com/go/vision) in preference to this.

This code is EXPERIMENTAL and subject to CHANGE AT ANY TIME.

func NewImageAnnotatorClient added in v0.3.0 

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 
ctx := context.Background()
c, err := vision.NewImageAnnotatorClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c

Output:

func (c *ImageAnnotatorClient) AnnotateImage(ctx context.Context, req *pb.AnnotateImageRequest, opts ...gax.CallOption) (*pb.AnnotateImageResponse, error)

AnnotateImage runs image detection and annotation for a single image.

Example 
package main

import (
	vision "cloud.google.com/go/vision/apiv1"
	"golang.org/x/net/context"

	pb "google.golang.org/genproto/googleapis/cloud/vision/v1"
)

func main() {
	ctx := context.Background()
	c, err := vision.NewImageAnnotatorClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	res, err := c.AnnotateImage(ctx, &pb.AnnotateImageRequest{
		Image: vision.NewImageFromURI("gs://my-bucket/my-image.png"),
		Features: []*pb.Feature{
			{Type: pb.Feature_LANDMARK_DETECTION, MaxResults: 5},
			{Type: pb.Feature_LABEL_DETECTION, MaxResults: 3},
		},
	})
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use res.
	_ = res
}

Output:
