SignalEnable Parameter

To control a specific signal, designate the corresponding item of the collection parameter. See MultiCam Collection Parameter and Enabling Signals for more information.

Only enabled signals will trigger a callback or satisfy any of the waiting functions.

Compatibility issue

Before MultiCam 2.3 release, the SignalEnable parameter was not a collection. It accepted three predefined values:

SignalEnable

Description

NONE

No signal is enabled

PROCESSING

The Surface Processing signal is enabled

FILLED

The Surface Processing and Surface Filled signals are enabled

Element #0 of the collection accepts any of the above values to ensure backward compatibility with releases before MultiCam 2.3.
