The Controls tab configures how metadata coming from the foreground input image gets added to the background input image.
The Operation menu determines how the metadata of the foreground and background inputs are treated.
— Merge (Replace Duplicates): All values are merged, but values with duplicate names are taken from the foreground input.
— Merge (Preserve Duplicates): All values are merged, but values with duplicate names are taken from the background input.
— Replace: The metadata in the foreground replaces the entire metadata in the background.
— Clear: All metadata is discarded.
Common Controls
The Settings tab in the Inspector is also duplicated in other Metadata nodes. These common controls are described in detail at the end of this chapter in “The Common Controls” section.
Set Metadata [SMeta]
The Set Metadata node
Set Metadata Node Introduction
Set Metadata allows you to create new Name = Value pairs in the metadata. Metadata can be viewed in a subview of the viewer.
Inputs
The single input on the Set Metadata node is used to connect a 2D image that gets metadata added.
— Background Input: The orange background input is used for the primary 2D image that is output from the node with the new metadata.
Basic Node Setup
The Set Metadata node embeds new metadata into the background input (orange). The output is the background input with new metadata.
