Properties| Name | Description | |
|---|---|---|
 | FileFormat |
Gets the type of the loaded file (if recognized).
|
Methods| Name | Description | |
|---|---|---|
| AddProperties |
Adds known metadata properties satisfying the specified predicate.
The operation is recursive so it affects all nested packages as well.
|
| Dispose |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
|
| Equals | (Inherited from Object.) |
| FindProperties |
Finds the metadata properties satisfying the specified predicate.
The search is recursive so it affects all nested packages as well.
|
| GeneratePreview |
Creates preview images for specified pages.
|
| GetDocumentInfo |
Gets common information about the loaded document.
|
| GetHashCode | (Inherited from Object.) |
| GetRootPackage |
Gets the root package providing access to all metadata properties extracted from the file.
|
| GetRootPackageTRoot |
Gets the root package providing access to all metadata properties extracted from the file.
|
| GetType | (Inherited from Object.) |
| RemoveProperties |
Removes metadata properties satisfying the specified predicate.
|
| Sanitize |
Removes writable metadata properties from all detected packages or whole packages if possible.
The operation is recursive so it affects all nested packages as well.
|
| Save |
Saves all changes made in the loaded document.
|
| Save(Stream) |
Saves the document content into a stream.
|
| Save(String) |
Saves the document content to the specified file.
|
| SetProperties |
Sets known metadata properties satisfying the specified predicate.
The operation is recursive so it affects all nested packages as well.
This method is a combination of AddProperties(FuncMetadataProperty, Boolean, PropertyValue) and UpdateProperties(FuncMetadataProperty, Boolean, PropertyValue).
If an existing property satisfies the predicate its value is updated.
If there is a known property missing in a package that satisfies the predicate it is added to the package.
|
| ToString | (Inherited from Object.) |
| UpdateProperties |
Updates known metadata properties satisfying the specified predicate.
The operation is recursive so it affects all nested packages as well.
