Specify image size in Telegram binding

Add-ons Bindings

Using the Telegram binding it is possible to specify an image which is posted along with the caption. However the image is always scaled up/down to fit the screen size - and sometimes that looks ugly.

Is it possible to specify the picture size which Telegram should use? The Telegram API seems to support this, at least there is a PhotoSize documentation. The openHAB binding can only add a URL or a base64 encoded image, but it’s not possible to specify or influence the actual picture size.

I made a small script just to do that

#!/bin/sh
SnapFile4="/var/tmp/image4.jpg"
TimeStamp=`/bin/date '+%Y%m%d_%H%M%S_%3N'`;
justtime=`/bin/date '+%d-%m-%Y at %H:%M'`;

# Send Telegram message with image
curl -s -X POST "https://api.telegram.org/botcbbcbcbcbcbcbc9ZDaX-trtr55e55e-TRYTREW/sendPhoto?chat_id=0000000000" -F chat_id=-000000000 -F disable_notification=false -F photo="@$SnapFile4" -F caption="This image send on $justtime "

Hope that’s not your bot uid, with just a few characters added :wink:

Ok, but by using a script you are no longer using the binding.
