An interface channels can implement to support a picture. Most of the time this will be implemented by channels implementing the Room2 interface. Note that this interface is not restricted to Text channels, and can also be used on Call channels.

This is a separate interface from RoomConfig1 because (a) it's possible some protocol might support pictures for 1:1 chats; and (b) it avoids downloading an unwanted picture in a GetAll request.
The new picture. The MIME type.

Set the room's picture. Clients SHOULD look at the picture flags before calling this method as the user might not have permission to set the picture.

A successful return of this method indicates a successful change in picture, but clients should still listen for changes to the Picture property for further changes by other users or the server.

Picture is somehow invalid: e.g. unsupported MIME type, too big, etc.

The picture representing this channel.

This property may change during the lifetime of the channel and MUST not be included in a channel request.

The normalized contact ID representing who last modified the picture, or the empty string if it is not known.

The handle corresponding to Actor, or 0 if the Actor is unknown.

A unix timestamp indicating when the picture was last modified, or INT_MAX64 if unknown.

TRUE if the Picture property can be set by the user by calling SetPicture, otherwise FALSE.

If implementations are unsure of what this value should be it SHOULD still be set to what it believes the value is. As a result, clients should be aware that SetPicture can still fail even with this property set to TRUE.

An array of supported MIME types (e.g. "image/jpeg"). Clients MAY assume that the first type in this array is preferred. The minimum height in pixels of the picture, which MAY be 0. The minimum width in pixels of the picture, which MAY be 0. The recommended height in pixels of the picture, or 0 if there is no preferred height. The recommended width in pixels of the picture, or 0 if there is no preferred width. The maximum height in pixels of the picture, or 0 if there is no limit. The maximum width in pixels of the picture, or 0 if there is no limit. The maximum size in bytes of the picture, or 0 if there is no limit.
