IWICMetadataWriter interface (wincodecsdk.h)
Exposes methods that provide access to writing metadata content. This is implemented by independent software vendors (ISVs) to create new metadata writers.
Inheritance
The IWICMetadataWriter interface inherits from IWICMetadataReader. IWICMetadataWriter also has these types of members:
Methods
The IWICMetadataWriter interface has these methods.
| IWICMetadataWriter::RemoveValue Removes the metadata item that matches the given parameters. |
| IWICMetadataWriter::RemoveValueByIndex Removes the metadata item at the specified index. |
| IWICMetadataWriter::SetValue Sets the given metadata item. |
| IWICMetadataWriter::SetValueByIndex Sets the metadata item to the specified index. |
Remarks
A metadata writer can be used to write metadata blocks and items within a metadata block instead of using a query writer. To directly access the metadata writer, query an encoder or its frames for the IWICMetadataBlockWriter interface to enumerate each metadata writer.
