"""Send photos.
|
|
|
|
Parameters:
|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
For your personal cloud (Saved Messages) you can simply use "me" or "self".
|
|
For a contact that exists in your Telegram address book you can use his phone number (str).
|
|
|
|
photo (``str``):
|
|
Photo to send.
|
|
Pass a file_id as string to send a photo that exists on the Telegram servers,
|
|
pass an HTTP URL as a string for Telegram to get a photo from the Internet, or
|
|
pass a file path as string to upload a new photo that exists on your local machine.
|
|
|
|
caption (``bool``, *optional*):
|
|
Photo caption, 0-1024 characters.
|
|
|
|
parse_mode (``str``, *optional*):
|
|
Pass "markdown" or "html" if you want Telegram apps to show bold, italic, fixed-width text or inline
|
|
URLs in your caption. Defaults to "markdown".
|
|
|
|
ttl_seconds (``int``, *optional*):
|
|
Self-Destruct Timer.
|
|
If you set a timer, the photo will self-destruct in *ttl_seconds*
|
|
seconds after it was viewed.
|
|
|
|
disable_notification (``bool``, *optional*):
|
|
Sends the message silently.
|
|
Users will receive a notification with no sound.
|
|
|
|
reply_to_message_id (``int``, *optional*):
|
|
If the message is a reply, ID of the original message.
|
|
|
|
reply_markup (:obj:`InlineKeyboardMarkup` | :obj:`ReplyKeyboardMarkup` | :obj:`ReplyKeyboardRemove` | :obj:`ForceReply`, *optional*):
|
|
Additional interface options. An object for an inline keyboard, custom reply keyboard,
|
|
instructions to remove reply keyboard or to force a reply from the user.
|
|
|
|
progress (``callable``, *optional*):
|
|
Pass a callback function to view the upload progress.
|
|
The function must take *(client, current, total, \*args)* as positional arguments (look at the section
|
|
below for a detailed description).
|
|
|
|
progress_args (``tuple``, *optional*):
|
|
Extra custom arguments for the progress callback function. Useful, for example, if you want to pass
|
|
a chat_id and a message_id in order to edit a message with the updated progress.
|
|
|
|
Other Parameters:
|
|
client (:obj:`Client`):
|
|
The Client itself, useful when you want to call other API methods inside the callback function.
|
|
|
|
current (``int``):
|
|
The amount of bytes uploaded so far.
|
|
|
|
total (``int``):
|
|
The size of the file.
|
|
|
|
*args (``tuple``, *optional*):
|
|
Extra custom arguments as defined in the *progress_args* parameter.
|
|
You can either keep *\*args* or add every single extra argument in your function signature.
|
|
|
|
Returns:
|
|
:obj:`Message` | ``None``: On success, the sent photo message is returned, otherwise, in case the upload
|
|
is deliberately stopped with :meth:`stop_transmission`, None is returned.
|
|
|
|
Raises:
|
|
RPCError: In case of a Telegram RPC error.
