SetUsageInfo Method

Description:

Sets a Usage dictionary entry in a layer object. The entry associates usage information with an entry key for retrieval. If a dictionary does not exist, the method creates one.

A Usage dictionary entry provides more specific intended usage information than an intent entry.

The usage value can act as a kind of metadata, describing the sort of things that belong to the layer: for example, text in French, fine detail on a map, or a watermark. The usage values can also be used by the AutoState mechanism to make decisions about what layers should be on and what layers should be off.

Syntax:

      SetUsageInfo(UsageKey As IGPDFAtom, UsageInfo As IIGPDFBasObj)

Parameters:
