void AI5EPSFilter::CleanUpAfterImport (  BOOL  Successful  )  [protected, virtual]

Author: Tim_Browse (Xara Group Ltd) <camelotdev@xara.com> Date: 12/08/94 Parameters: Successful  - TRUE if the import was successful. [INPUTS] See also: EPSFilter::CleanUpAfterImport Reimplemented from EPSFilter.

BOOL AI5EPSFilter::CreateLayer (  String_256 &  LayerName, BOOL  IsLocked, BOOL  IsPrintable, BOOL  IsVisible )

Author: Graeme_Sutherland (Xara Group Ltd) <camelotdev@xara.com> Date: 17/4/00 Parameters: LayerName  - The name of the new layer. [INPUTS] IsLocked - Is the layer locked? IsPrintable - Is the layer printable? IsVisible - Is the layer visible? Returns: TRUE - Success. FALSE - Failure - the layer wasn't created.
