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.

Overview

Package vision is an experimental, auto-generated package for the 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 the client at cloud.google.com/go/vision in preference to this.

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 Google Cloud Vision API.

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

Output:

func (*ImageAnnotatorClient) AnnotateImage 

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:

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 
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
