Requesting Changes

To update a Control the client should send a block of the same form Ultimatte sends when

its status changes. For example, to change Matte Density to 100, the client should send the

following block:

Matte Density: 100 ↵

The block must be terminated by a blank line. On receipt of a blank line, Ultimatte will either

acknowledge the request by responding:

or indicate that the request was not understood by responding:

After a positive response, the client should expect to see a status update from Ultimatte

showing the status change. This is likely to be the same as the command that was sent, but

if the request could not be performed, or other changes were made simultaneously by other

clients, there may be more updates in the block, or more blocks. Simultaneous updates could

cancel each other out, leading to a response that is different to that expected.

In the absence of simultaneous updates, a simple control change will result in the following

protocol exchange:

Matte Density: 0 ↵

Matte Density: 0 ↵

The asynchronous nature of the responses means that a client should never rely on the desired

update actually occurring and must simply watch for status updates from Ultimatte and use only

these to update its local representation of Ultimatte's state.

A client may also request Ultimatte to change a control by a relative amount. For example,

to change Matte Density by 10, the client should send the following block:

Offset Matte Density: 10 ↵

Only controls with numerical ranges support this relative mode.

Requesting a Status Dump

The client may request that Ultimatte resend the complete state of any status block by sending

the header of the block, followed by a blank line. In the following example, the client requests

Ultimatte resend the control status:
