public enum FlattenFlag
  Member nameValueDescription
e_off0 Disable flattening and convert all content as is.
e_simple1 Feature reduce PDF to a simple two layer representation consisting of a single background RGB image and a simple top text layer.
e_fast2 Feature reduce PDF while trying to preserve some complex PDF features (such as vector figures, transparency, shadings, blend modes, Type3 fonts etc.) for pages that are already fast to render. This option can also result in smaller and faster files compared to e_simple, but the pages may have more complex structure.
e_high_quality3 Preserve vector content where possible. In particular only feature reduce PDF files containing overprint or very complex vector content. Currently this option can only be used with XODOutputOptions.
