Purpose¶

The module Switch selects one of several input images to output.

The selected image is passed unchanged to the output, even if the input is not connected or the input image is undefined.

Note that it is not necessary for all inputs to be connected. Unconnected or undefined inputs are bypassed as an undefined (empty) image.

Notifications are only propagated for the selected input, while notifications from all other inputs are ignored.

The number of shown inputs can be changed.

Tips¶

If a switch “UseSomething” is used to either use or bypass a subnetwork implementing a feature “Something”, the latter should be connected to the second input. This way, the bi-valued Active Input Index can be used like a regular boolean, with 1 meaning “use Something” and 0 meaning “don’t use Something”.
