Metadata

ObjectData is easily confused with regular Image Metadata. However, Image Metadata can only be read with scripts, but not changed, as it is tied to the Image Stream itself. You will need Fuses or Plugins to change the Image Stream and its Metadata directly. In order to access it, you will need to evaluate the Output up to the point where the Metadata was queried.

This is not needed in the case of ObjectData, as it depends on the Object instance and not on its underlying data stream.

In a Loader with a valid input access is Metadata like this:


==Loader1.Output[comp.CurrentTime].Metadata.Filename


In SimpleExpression, the evaluation is not needed, as it is automatically evaluated at the current time. For example put this in a text field’s Expression field:

Loader1.Output.Metadata.Filename
