| flags | The new import flags. | 16 |
Result
Returns OK.
Description
Sets optional flags to control the import of external PDF files.Flags to pass:
| MergeLayers | 1 | If 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. |
| Normalize | 2 | Replace LZW compression with Flate, apply limit checks, repair errors if possible |
| UseProxy | 4 | Not 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. |
| NoMetadata | 8 | Ignore metadata streams which are attached to fonts, pages, images, and so on. |
| DuplicateCheck | 16 | Perform a duplicate check on color spaces, fonts, images, patterns, and templates when merging PDF files. |
