when using MARKDOWN, (),

what is the format to indicate a width  limite (to 200px eg or to the size of the desktop messag area ?). 

Currently, image is  pushed 100% of its original width which is overflowing the display screen sometimes .

  Hi Patrice,

   

  The only tags supported are (https://hub.openrainbow.com/#/documentation/doc/sdk/node/guides/Answering_chat_message) as described:

  Interaction with Rainbow clients

  ---

  At this time of writting, Rainbow clients manage Message language and are able to display messages using a Markdown content type. This feature is not officially supported but if your Node.JS application interacts with a Rainbow official client, this can help.
  
  Here is the list of Markdown tags supported by the Rainbow official Web application (Rainbow Web client and Rainbow Desktop client):

  • Headers: #H1 to ######H6

  • Emphasis: *italics* and **bold**

  • Lists: -, + or `* ``

  • Links: [a link](https://www.hub.openrainbow.com)

  • Images ![alt text](https://hub.openrainbow.com/img/logohub.svg)

  • Code: Inline code has back-ticks around it.

  • Blockquotes: > a Blockquote.

  Note: Other Markdown tags can be used specifically if you have provided your own end-user application but will not be rendered correcly in the Rainbow official clients.
  
  Subject is used when displaying Rainbow notification messages.
  
  Note: At this time of writing, Markdown is not supported by the Rainbow mobile clients.

  and no way to force an image size.

  No way described also in official Markdown doc: https://daringfireball.net/projects/markdown/syntax#img

  Up to you to resize the image before including them to the message.  Or if your server is "resize on the fly" - capable, use it 
  For example on some servers: src="/images/the_img.jpg?w=120" to force it at 120px width

  Warning also to share an https// image url !  Instead of that all clients in HTML5 will display a Warning "mixed content".

   

  Best regards,
  Pascal

  On-the-fly resizing must be supported by Rainbow Clients (web, desktop, smartphone) . So if you don't support, as indicated, this means that I must must have a "resizing process" on server side which is very time-consuming and unefficient. Bad news

  Please add a request to Markdown project for adding an image size to

  • Images ![alt text](https://hub.openrainbow.com/img/logohub.svg)

  =>  not linked to Rainbow.

   

  Please read my reply.  You said "On-the-fly resizing must be supported by Rainbow Clients", I said: up to your server, where the image is hosted (not Rainbow servers) to resize the image if possible.

  Or as I said also, before attaching the IMG in your Markdown message, up to you to resize it in your code !

  understand but when the IMG is a LINK (URL to another site than us). [like in NEWS FEEDS] where we link to the outher server image, the lack of resizing support on Rainbow imposes some IMG download + resize + storage for nothing while a simple MARKDOWN support would be enough.

  Client's side, if you share an image in a conversation, it's also an URL link, as if it is stored Rainbow's side. 
  And the resize is also done "on the fly" client's side or server's side for larger images.
