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.

Types

type AsyncBatchAnnotateFilesOperation added in v0.26.0

Done reports whether the long-running operation has completed.

func (*AsyncBatchAnnotateFilesOperation) Metadata added in v0.26.0 

func (op *AsyncBatchAnnotateFilesOperation) Metadata() (*visionpb.OperationMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*AsyncBatchAnnotateFilesOperation) Name added in v0.26.0 

func (op *AsyncBatchAnnotateFilesOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*AsyncBatchAnnotateFilesOperation) Wait added in v0.26.0

CreateReferenceImage creates and returns a new ReferenceImage resource.

The bounding_poly field is optional. If bounding_poly is not specified, the system will try to detect regions of interest in the image that are compatible with the product_category on the parent product. If it is specified, detection is ALWAYS skipped. The system converts polygons into non-rotated rectangles.

Note that the pipeline will resize the image if the image resolution is too large to process (above 50MP).

Possible errors: 

Returns INVALID_ARGUMENT if the image_uri is missing or longer than 4096
characters.

Returns INVALID_ARGUMENT if the product does not exist.

Returns INVALID_ARGUMENT if bounding_poly is not provided, and nothing

Output:

func (*ProductSearchClient) DeleteReferenceImage added in v0.33.1 

func (c *ProductSearchClient) DeleteReferenceImage(ctx context.Context, req *visionpb.DeleteReferenceImageRequest, opts ...gax.CallOption) error

DeleteReferenceImage permanently deletes a reference image.

The image metadata will be deleted right away, but search queries against ProductSets containing the image may still work until all related caches are refreshed.

The actual image files are not deleted from Google Cloud Storage.

Possible errors: 

Returns NOT_FOUND if the reference image does not exist.

package main

import (
	"context"
