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.

Documentation

Overview

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

func (c *ProductSearchClient) CreateReferenceImage(ctx context.Context, req *visionpb.CreateReferenceImageRequest, opts ...gax.CallOption) (*visionpb.ReferenceImage, error)

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
compatible with the parent product's product_category is detected.

Returns INVALID_ARGUMENT if bounding_poly contains more than 10 polygons.
