Getting Started

You will need a google account to use this API so if you do not already have an account with google, head over there and create one, _(*2)

Installation

```bash composer require wapnen/google-cloud-vision-php, _(*3)


## Enable the API
  To start using the google cloud vision api, follow the instructions here to enable the api for your google account https://cloud.google.com/vision/docs/before-you-begin

## Authentication
  You must set up an Api key to authenticate your requests. Follow the instructions here https://support.google.com/cloud/answer/6158862?hl=en to set up an API key for your project on google cloud platform console

# Usage

setImageUri("https://cdn.pixabay.com/photo/2016/02/19/11/25/supreme-court-building-1209701_960_720.jpg"); $annotateImageRequest1->setFeature('IMAGE_PROPERTIES'); $annotateImageRequest1->setFeature('LABEL_DETECTION'); $annotateImageRequest1->setFeature('WEB_DETECTION'); $gcvRequest = new GoogleCloudVision([$annotateImageRequest1], "Your_api_key"); $response = $gcvRequest->annotate(); echo json_encode($response); ?>

Note : You can create as many as 16 Annotate image requests to be sent with the request object

The function ```setImageUri();``` takes a Google Cloud Storage image location, or publicly-accessible image URL. Alternatively you can use ```setImage();``` which takes a base64 encoded image string.

You can set as many features as are available to the annotateImageRequest by calling the ```setFeature();``` function on the annotateImageRequest which takes any of the following enum parameters ; TYPE_UNSPECIFIED, FACE_DETECTION, LANDMARK_DETECTION, LOGO_DETECTION, LABEL_DETECTION, TEXT_DETECTION, DOCUMENT_TEXT_DETECTION, SAFE_SEARCH_DETECTION, IMAGE_PROPERTIES, CROP_HINTS, WEB_DETECTION.

Optionally, you can set the image context for each annotateImageRequest object like so

$annotateImageRequest1 = new AnnotateImageRequest() $annotateImageRequest1->setImageContext(); $annotateImageRequest1->getImageContext()->setCropHintsParams([1.333]); //array $annotateImageRequest1->getImageContext()->setWebDetectionParams(false); //boolean $annotateImageRequest1->getImageContext()->setLanguageHints([]); //array, _(*4)

Finally, the GoogleCloudVision request object takes an array of AnnotateImageRequest objects as the first parameter and the api key as the second parameter

### Response object
If successful, you will receive a json object response in the format below;

{ "responses": [ { object(AnnotateImageResponse) } ] } ```, _(*5)
