IWICMetadataWriter interface
Exposes methods that provide access to writing metadata content. This is implemented by independent software vendors (ISVs) to create new metadata writers.
Members
The IWICMetadataWriter interface inherits from IWICMetadataReader. IWICMetadataWriter also has these types of members:

| RemoveValueByIndex |

| SetValue |
