// ImagesClient is the visual Search API lets you discover insights about an image such as visually similar images,
// shopping sources, and related searches. The API can also perform text recognition, identify entities (people,
// places, things), return other topical content for the user to explore, and more. For more information, see [Visual
// Search Overview](https://docs.microsoft.com/azure/cognitive-services/bing-visual-search/overview).  **NOTE:** To
// comply with the new EU Copyright Directive in France, the Bing Visual Search API must omit some content from certain
// EU News sources for French users. The removed content may include thumbnail images and videos, video previews, and
// snippets which accompany search results from these sources. As a consequence, the Bing APIs may serve fewer results
// with thumbnail images and videos, video previews, and snippets to French users.

// VisualSearch sends the visual search request.
// Parameters:
// acceptLanguage - a comma-delimited list of one or more languages to use for user interface strings. The list
// is in decreasing order of preference. For additional information, including expected format, see
// [RFC2616](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html). This header and the
// [setLang](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-visual-search-api-v7-reference#setlang)
// query parameter are mutually exclusive; do not specify both. If you set this header, you must also specify
// the [cc](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-visual-search-api-v7-reference#cc)
// query parameter. To determine the market to return results for, Bing uses the first supported language it
// finds from the list and combines it with the cc parameter value. If the list does not include a supported
// language, Bing finds the closest language and market that supports the request or it uses an aggregated or
// default market for the results. To determine the market that Bing used, see the BingAPIs-Market header. Use
// this header and the cc query parameter only if you specify multiple languages. Otherwise, use the
// [mkt](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-visual-search-api-v7-reference#mkt)
// and
// [setLang](https://docs.microsoft.com/en-us/rest/api/cognitiveservices/bing-visual-search-api-v7-reference#setlang)
// query parameters. A user interface string is a string that's used as a label in a user interface. There are
// few user interface strings in the JSON response objects. Any links to Bing.com properties in the response
// objects apply the specified language.
// contentType - must be set to multipart/form-data and include a boundary parameter (for example,
// multipart/form-data; boundary=<boundary string>). For more details, see [Content form types](
// https://docs.microsoft.com/en-us/azure/cognitive-services/bing-visual-search/overview#content-form-types).
// userAgent - the user agent originating the request. Bing uses the user agent to provide mobile users with an
// optimized experience. Although optional, you are encouraged to always specify this header. The user-agent
// should be the same string that any commonly used browser sends. For information about user agents, see [RFC
// 2616](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html). The following are examples of user-agent
// strings. Windows Phone: Mozilla/5.0 (compatible; MSIE 10.0; Windows Phone 8.0; Trident/6.0; IEMobile/10.0;
// ARM; Touch; NOKIA; Lumia 822). Android: Mozilla / 5.0 (Linux; U; Android 2.3.5; en - us; SCH - I500 Build /

// clientID - bing uses this header to provide users with consistent behavior across Bing API calls. Bing often
// flights new features and improvements, and it uses the client ID as a key for assigning traffic on different
// flights. If you do not use the same client ID for a user across multiple requests, then Bing may assign the
// user to multiple conflicting flights. Being assigned to multiple conflicting flights can lead to an
// inconsistent user experience. For example, if the second request has a different flight assignment than the
// first, the experience may be unexpected. Also, Bing can use the client ID to tailor web results to that
// client ID’s search history, providing a richer experience for the user. Bing also uses this header to help
// improve result rankings by analyzing the activity generated by a client ID. The relevance improvements help
// with better quality of results delivered by Bing APIs and in turn enables higher click-through rates for the
// API consumer. IMPORTANT: Although optional, you should consider this header required. Persisting the client
// ID across multiple requests for the same end user and device combination enables 1) the API consumer to
// receive a consistent user experience, and 2) higher click-through rates via better quality of results from
// the Bing APIs. Each user that uses your application on the device must have a unique, Bing generated client
// ID. If you do not include this header in the request, Bing generates an ID and returns it in the
// X-MSEdge-ClientID response header. The only time that you should NOT include this header in a request is the
// first time the user uses your app on that device. Use the client ID for each Bing API request that your app
// makes for this user on the device. Persist the client ID. To persist the ID in a browser app, use a
// persistent HTTP cookie to ensure the ID is used across all sessions. Do not use a session cookie. For other
// apps such as mobile apps, use the device's persistent storage to persist the ID. The next time the user uses
// your app on that device, get the client ID that you persisted. Bing responses may or may not include this
// header. If the response includes this header, capture the client ID and use it for all subsequent Bing
// requests for the user on that device. ATTENTION: You must ensure that this Client ID is not linkable to any
// authenticatable user account information. If you include the X-MSEdge-ClientID, you must not include cookies
// in the request.
// clientIP - the IPv4 or IPv6 address of the client device. The IP address is used to discover the user's
// location. Bing uses the location information to determine safe search behavior. Although optional, you are
// encouraged to always specify this header and the X-Search-Location header. Do not obfuscate the address (for
// example, by changing the last octet to 0). Obfuscating the address results in the location not being
// anywhere near the device's actual location, which may result in Bing serving erroneous results.
// location - a semicolon-delimited list of key/value pairs that describe the client's geographical location.
// Bing uses the location information to determine safe search behavior and to return relevant local content.
// Specify the key/value pair as <key>:<value>. The following are the keys that you use to specify the user's
// location. lat (required): The latitude of the client's location, in degrees. The latitude must be greater
// than or equal to -90.0 and less than or equal to +90.0. Negative values indicate southern latitudes and
// positive values indicate northern latitudes. long (required): The longitude of the client's location, in
// degrees. The longitude must be greater than or equal to -180.0 and less than or equal to +180.0. Negative
// values indicate western longitudes and positive values indicate eastern longitudes. re (required): The
// radius, in meters, which specifies the horizontal accuracy of the coordinates. Pass the value returned by
// the device's location service. Typical values might be 22m for GPS/Wi-Fi, 380m for cell tower triangulation,
// and 18,000m for reverse IP lookup. ts (optional): The UTC UNIX timestamp of when the client was at the
// location. (The UNIX timestamp is the number of seconds since January 1, 1970.) head (optional): The client's
// relative heading or direction of travel. Specify the direction of travel as degrees from 0 through 360,
// counting clockwise relative to true north. Specify this key only if the sp key is nonzero. sp (optional):
// The horizontal velocity (speed), in meters per second, that the client device is traveling. alt (optional):
// The altitude of the client device, in meters. are (optional): The radius, in meters, that specifies the
// vertical accuracy of the coordinates. Specify this key only if you specify the alt key. Although many of the
// keys are optional, the more information that you provide, the more accurate the location results are.
// Although optional, you are encouraged to always specify the user's geographical location. Providing the
// location is especially important if the client's IP address does not accurately reflect the user's physical
// location (for example, if the client uses VPN). For optimal results, you should include this header and the
// X-MSEdge-ClientIP header, but at a minimum, you should include this header.
// market - the market where the results come from. Typically, mkt is the country where the user is making the
// request from. However, it could be a different country if the user is not located in a country where Bing
// delivers results. The market must be in the form <language code>-<country code>. For example, en-US. The
// string is case insensitive. For a list of possible market values, see [Market
// Codes](https://docs.microsoft.com/en-us/azure/cognitive-services/bing-visual-search/supported-countries-markets).
// NOTE: If known, you are encouraged to always specify the market. Specifying the market helps Bing route the
// request and return an appropriate and optimal response. If you specify a market that is not listed in
// [Market
// Codes](https://docs.microsoft.com/en-us/azure/cognitive-services/bing-visual-search/supported-countries-markets),
// Bing uses a best fit market code based on an internal mapping that is subject to change.
// safeSearch - filter the image results in actions with type 'VisualSearch' for adult content. The following
// are the possible filter values. Off: May return images with adult content. Moderate: Do not return images
// with adult content. Strict: Do not return images with adult content. The default is Moderate. If the request
// comes from a market that Bing's adult policy requires that safeSearch is set to Strict, Bing ignores the
// safeSearch value and uses Strict. If you use the site: filter in the knowledge request, there is the chance
// that the response may contain adult content regardless of what the safeSearch query parameter is set to. Use
// site: only if you are aware of the content on the site and your scenario supports the possibility of adult
// content.
// setLang - the language to use for user interface strings. Specify the language using the ISO 639-1 2-letter
// language code. For example, the language code for English is EN. The default is EN (English). Although
// optional, you should always specify the language. Typically, you set setLang to the same language specified
// by mkt unless the user wants the user interface strings displayed in a different language. A user interface
// string is a string that's used as a label in a user interface. There are few user interface strings in the
// JSON response objects. Also, any links to Bing.com properties in the response objects apply the specified
// language.
// knowledgeRequest - the form data is a JSON object that identifies the image using an insights token or URL
// to the image. The object may also include an optional crop area that identifies an area of interest in the
// image. The insights token and URL are mutually exclusive – do not specify both. You may specify
// knowledgeRequest form data and image form data in the same request only if knowledgeRequest form data
// specifies the cropArea field only (it must not include an insights token or URL).
// imageParameter - the form data is an image binary. The Content-Disposition header's name parameter must be
// set to "image". You must specify an image binary if you do not use knowledgeRequest form data to specify the
// image; you may not use both forms to specify an image. You may specify knowledgeRequest form data and image
// form data in the same request only if knowledgeRequest form data specifies the cropArea field only  (it must
// not include an insights token or URL).
