Image(Image)

public Image(Image other)

Parameter
Name	Description
`other`	`Image`

Properties

Content

public ByteString Content { get; set; }

Image content, represented as a stream of bytes. Note: As with all bytes fields, protobuffers use a pure binary representation, whereas JSON representations use base64.

Currently, this field only works for BatchAnnotateImages requests. It does not work for AsyncBatchAnnotateImages requests.

Property Value
Type	Description
`ByteString`

Source

public ImageSource Source { get; set; }

Google Cloud Storage image location, or publicly-accessible image URL. If both content and source are provided for an image, content takes precedence and is used to perform the image annotation request.

Property Value
Type	Description
`ImageSource`

Methods

FetchFromUri(String, HttpClient)

public static Image FetchFromUri(string uri, HttpClient httpClient = null)

Constructs an Image by downloading data from the given URI.

Parameters
Name	Description
`uri`	`String` The URI to fetch. Must not be null.
`httpClient`	`HttpClient` The HttpClient to use to fetch the image, or `null` to use a default client.

Returns
Type	Description
`Image`	The newly created image.

Remarks

Unlike FromUri(String), this method downloads the image locally then uploads it to the Google Cloud Vision server.

FetchFromUri(Uri, HttpClient)

public static Image FetchFromUri(Uri uri, HttpClient httpClient = null)

Constructs an Image by downloading data from the given URI.

Parameters
Name	Description
`uri`	`Uri` The URI to fetch. Must not be null.
`httpClient`	`HttpClient` The HttpClient to use to fetch the image, or `null` to use a default client.

Returns
Type	Description
`Image`	The newly created image.

Remarks

Unlike FromUri(String), this method downloads the image locally then uploads it to the Google Cloud Vision server.

FetchFromUriAsync(String, HttpClient)

public static Task<Image> FetchFromUriAsync(string uri, HttpClient httpClient = null)

Asynchronously constructs an Image by downloading data from the given URI.

Parameters
Name	Description
`uri`	`String` The URI to fetch. Must not be null.
`httpClient`	`HttpClient` The HttpClient to use to fetch the image, or `null` to use a default client.

Returns
Type	Description
`Task<Image>`	A task representing the asynchronous operation. The result will be the newly created image.

Remarks

Unlike FromUri(Uri), this method downloads the image locally then uploads it to the Google Cloud Vision server.

FetchFromUriAsync(Uri, HttpClient)

public static Task<Image> FetchFromUriAsync(Uri uri, HttpClient httpClient = null)

Asynchronously constructs an Image by downloading data from the given URI.

Parameters
Name	Description
`uri`	`Uri` The URI to fetch. Must not be null.
`httpClient`	`HttpClient` The HttpClient to use to fetch the image, or `null` to use a default client.

Returns
Type	Description
`Task<Image>`	A task representing the asynchronous operation. The result will be the newly created image.

Remarks

Unlike FromUri(Uri), this method downloads the image locally then uploads it to the Google Cloud Vision server.

FromBytes(Byte[])

public static Image FromBytes(byte[] bytes)

Constructs an Image from the given byte array.

Parameter
Name	Description
`bytes`	`Byte[]` The bytes representing the raw image data.

Returns
Type	Description
`Image`	The newly created image.

Remarks

This method copies the data from the byte array; modifications to bytes after this method returns will not be reflected in the image.

FromBytes(Byte[], Int32, Int32)

public static Image FromBytes(byte[] bytes, int offset, int count)

Constructs an Image from a section of the given byte array.

Parameters
Name	Description
`bytes`	`Byte[]` The bytes representing the raw image data.
`offset`	`Int32` The offset into the byte array of the start of the data to include in the image.
`count`	`Int32` The number of bytes to include in the image.

Returns
Type	Description
`Image`	The newly created image.

Remarks

This method copies the data from the byte array; modifications to bytes after this method returns will not be reflected in the image.

FromFile(String)

public static Image FromFile(string path)

Constructs an Image by loading data from the given file path.

Parameter
Name	Description
`path`	`String` The file path to load image data from. Must not be null.
