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.

---|---|
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.

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
|
Returns | |
---|---|
Type | Description |
Image | The newly created image. |
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
|
Returns | |
---|---|
Type | Description |
Image | The newly created image. |
Unlike FromUri(String), this method downloads the image locally then uploads it to the Google Cloud Vision server.
FetchFromUriAsync(String, HttpClient)
public static async 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
|
Returns | |
---|---|
Type | Description |
Task<Image> | A task representing the asynchronous operation. The result will be the newly created image. |
Unlike FromUri(Uri), this method downloads the image locally then uploads it to the Google Cloud Vision server.
FetchFromUriAsync(Uri, HttpClient)
public static async 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
|
Returns | |
---|---|
Type | Description |
Task<Image> | A task representing the asynchronous operation. The result will be the newly created image. |
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)

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