Component Version macOS Windows Server FileMaker Cloud FileMaker iOS SDK
DynaPDF 4.3 Yes Yes Yes Yes Yes

MBS( "DynaPDF.SetImportFlags2"; flags )

Parameters

Parameter Description Example value
flags The new import flags. 16

Result

Returns OK.

Description

Sets optional flags to control the import of external PDF files.

Flags to pass:
MergeLayers1If set, layers with identical name are merged. If this flag is absent DynaPDF imports such layers separately so that each layer refers still to the pages where it was originally used.
Normalize2Replace LZW compression with Flate, apply limit checks, repair errors if possible
UseProxy4Not meaningful for PDF files which are loaded from a memory buffer. If set, all streams are loaded from the file on demand but they are never hold in memory. This reduces drastically the memory usage and enables the processing of almost arbitrary large PDF files with minimal memory usage. The corresponding PDF file must not be deleted before DynaPDF.CloseFile or DynaPDF.CloseFileEx was called.
NoMetadata8Ignore metadata streams which are attached to fonts, pages, images, and so on.
DuplicateCheck16Perform a duplicate check on color spaces, fonts, images, patterns, and templates when merging PDF files.

See also SetImportFlags2 function in DynaPDF manual.
