SDFDocSaveAsync Method (IFilter, SDFDocSaveOptions, String) |
Namespace: pdftron.SDF
public IAsyncAction SaveAsync( IFilter filter, SDFDocSaveOptions flags, string header )
In a multi-threaded environment, the user is expected to acquire a write lock before attempting to save the document.
The save options can be combined using bitwise OR operations.
The new file header is only set when performing a full save.
A full save with remove unused or linearization option may re-arrange object in the cross reference table. Therefore all pointers and references to document objects and resources should be re-acquired in order to continue document editing.
If the original pdf has a corrupt xref table (see HasRepairedXref or http://www.pdftron.com/kb_corrupt_xref), then it can not be saved using the e_incremental flag.
