Overview

Package computervision implements the Azure ARM Computervision service API version 3.0-preview.

The Computer Vision API provides state-of-the-art algorithms to process images and return information. For example, it can be used to determine if an image contains mature content, or it can be used to find all the faces in an image. It also has other features like estimating dominant and accent colors, categorizing the content of images, and describing an image with complete English sentences. Additionally, it can also intelligently generate images thumbnails for displaying large images effectively.

Functions

func UserAgent 

func UserAgent() string

UserAgent returns the UserAgent string to use when sending http.Requests.

func Version 

func Version() string

Version returns the semantic version (see http://semver.org) of the client.

Types

type AnalyzeResults 

type AnalyzeResults struct {
	// Version - Version of schema used for this result.
	Version *string `json:"version,omitempty"`
	// ReadResults - Text extracted from the input.
	ReadResults *[]ReadResult `json:"readResults,omitempty"`
}

AnalyzeResults analyze batch operation result.

type BaseClient 

type BaseClient struct {
	autorest.Client
	Endpoint string
}

BaseClient is the base client for Computervision.

func New 

func New(endpoint string) BaseClient

New creates an instance of the BaseClient client.

func NewWithoutDefaults 

func NewWithoutDefaults(endpoint string) BaseClient

NewWithoutDefaults creates an instance of the BaseClient client.

func (BaseClient) GetReadResult 

func (client BaseClient) GetReadResult(ctx context.Context, operationID uuid.UUID) (result ReadOperationResult, err error)

GetReadResult this interface is used for getting OCR results of Read operation. The URL to this interface should be retrieved from 'Operation-Location' field returned from Read interface. Parameters: operationID - id of read operation returned in the response of the 'Read' interface.

func (BaseClient) GetReadResultPreparer 

func (client BaseClient) GetReadResultPreparer(ctx context.Context, operationID uuid.UUID) (*http.Request, error)

GetReadResultPreparer prepares the GetReadResult request.

func (BaseClient) GetReadResultResponder 

func (client BaseClient) GetReadResultResponder(resp *http.Response) (result ReadOperationResult, err error)

GetReadResultResponder handles the response to the GetReadResult request. The method always closes the http.Response Body.

func (BaseClient) GetReadResultSender 

func (client BaseClient) GetReadResultSender(req *http.Request) (*http.Response, error)

GetReadResultSender sends the GetReadResult request. The method will close the http.Response Body if it receives an error.

func (BaseClient) Read 

func (client BaseClient) Read(ctx context.Context, imageURL ImageURL, language OcrDetectionLanguage) (result autorest.Response, err error)

Read use this interface to get the result of a Read operation, employing the state-of-the-art Optical Character Recognition (OCR) algorithms optimized for text-heavy documents. When you use the Read interface, the response contains a field called 'Operation-Location'. The 'Operation-Location' field contains the URL that you must use for your 'GetReadResult' operation to access OCR results.​ Parameters: imageURL - a JSON document with a URL pointing to the image that is to be analyzed. language - the BCP-47 language code of the text to be detected in the image. In future versions, when language parameter is not passed, language detection will be used to determine the language. However, in the current version, missing language parameter will cause English to be used. To ensure that your document is always parsed in English without the use of language detection in the future, pass “en” in the language parameter

func (BaseClient) ReadInStream 

func (client BaseClient) ReadInStream(ctx context.Context, imageParameter io.ReadCloser, language OcrDetectionLanguage) (result autorest.Response, err error)

ReadInStream use this interface to get the result of a Read operation, employing the state-of-the-art Optical Character Recognition (OCR) algorithms optimized for text-heavy documents. When you use the Read interface, the response contains a field called 'Operation-Location'. The 'Operation-Location' field contains the URL that you must use for your 'GetReadResult' operation to access OCR results.​ Parameters: imageParameter - an image stream. language - the BCP-47 language code of the text to be detected in the image. In future versions, when language parameter is not passed, language detection will be used to determine the language. However, in the current version, missing language parameter will cause English to be used. To ensure that your document is always parsed in English without the use of language detection in the future, pass “en” in the language parameter

func (BaseClient) ReadInStreamPreparer 

func (client BaseClient) ReadInStreamPreparer(ctx context.Context, imageParameter io.ReadCloser, language OcrDetectionLanguage) (*http.Request, error)

func (BaseClient) ReadInStreamSender 

func (client BaseClient) ReadInStreamSender(req *http.Request) (*http.Response, error)

ReadInStreamSender sends the ReadInStream request. The method will close the http.Response Body if it receives an error.

func (BaseClient) ReadPreparer 

func (client BaseClient) ReadPreparer(ctx context.Context, imageURL ImageURL, language OcrDetectionLanguage) (*http.Request, error)

ReadPreparer prepares the Read request.

func (BaseClient) ReadResponder
