Represents a thumbnail inlined in a media (like the stripped preview of a photo, or the thumbnail of a secret chat media).  


It behaves like any other thumbnail, but it's downloaded from memory, without contacting Telegram:
its file ID carries the thumbnail itself, authenticated by the session that generated it: it's accepted by
every method of that session (not by the bot API, nor by other sessions).

* [`getDownloadInfo(): array`](#getDownloadInfo)
* [`getDownloadLink((string|null) $scriptUrl = NULL): string`](#getDownloadLink)
* [`getStream((callable(float, float, float): voi)|null) $cb = NULL, int $offset = 0, int $end = -1, ?\Amp\Cancellation $cancellation = NULL): \Amp\ByteStream\ReadableStream&danog\MadelineProto\ResumableStream`](#getStream)
* [`downloadToDir(string $dir = NULL, (callable(float, float, float): voi)|null) $cb = NULL, ?\Amp\Cancellation $cancellation = NULL): string`](#downloadToDir)
* [`downloadToFile(string $file, (callable(float, float, float): voi)|null) $cb = NULL, ?\Amp\Cancellation $cancellation = NULL): string`](#downloadToFile)

## Methods:
### <a name="getDownloadInfo"></a> `getDownloadInfo(): array`





### <a name="getDownloadLink"></a> `getDownloadLink((string|null) $scriptUrl = NULL): string`

Gets a download link for any file up to 4GB.


Parameters:

* `$scriptUrl`: `(string|null)` Optional path to custom download script (not needed when running via web)  



### <a name="getStream"></a> `getStream((callable(float, float, float): voi)|null) $cb = NULL, int $offset = 0, int $end = -1, ?\Amp\Cancellation $cancellation = NULL): \Amp\ByteStream\ReadableStream&danog\MadelineProto\ResumableStream`

Get a readable amp stream with the file contents.
  
The returned stream is resumable: it can be serialized, and once unserialized,  
reading continues from the end of the last chunk read before serialization.  


Parameters:

* `$cb`: `(callable(float, float, float): voi)|null)` Progress callback  
* `$offset`: `int`   
* `$end`: `int`   
* `$cancellation`: `?\Amp\Cancellation`

### <a name="downloadToDir"></a> `downloadToDir(string $dir = NULL, (callable(float, float, float): voi)|null) $cb = NULL, ?\Amp\Cancellation $cancellation = NULL): string`

Download the media to working directory or passed path.


Parameters:

* `$dir`: `string` Directory where to download the file  
* `$cb`: `(callable(float, float, float): voi)|null)` Progress callback  
* `$cancellation`: `?\Amp\Cancellation`

### <a name="downloadToFile"></a> `downloadToFile(string $file, (callable(float, float, float): voi)|null) $cb = NULL, ?\Amp\Cancellation $cancellation = NULL): string`

Download the media to file.


Parameters:

* `$file`: `string` Downloaded file path  
* `$cb`: `(callable(float, float, float): voi)|null)` Progress callback
