Is there a way using the plugin to flatten metadata layers and export / save the PDF? We've found that some viewers have issues viewing this metadata and would rather flatten the layered data to avoid issues.
Thanks. |

Hi
PDFium provides no way at present to modify the meta-data of a PDF file.

Nigel,
Thank you for letting me know. I suppose printing to a PDF printer might flatten the PDF. I need to test to see what it does.
I was thinking that as a last resort, maybe exporting each page as an image and then importing the image as a page within the PDF. |

Hi
If you were to open the PDF in ImageEn and then save it using ImageEn's native PDF that would convert each page to an image and you could remove all of the meta-data, e.g.
http://www.imageen.com/help/TIOParams.PDF_Author.html
In fact, you should just be able to use:
ImageEnMView.MIO.LoadFromFile('in.pdf');
ImageEnMView.MIO.SaveToFile('out.pdf');
That would use PDFium to get an image of each page, and then save it using ImageEn's native PDF saving to output each image as a page.
Note: I did not test it, but OTOMH it should work.

I gave this a try, and it does work. The only downside is that it increases the file size by about 4 times the original (1.2MB to 5MB).
If I print the PDF to the "Microsoft Print to PDF" printer, it only increases it by 65KB.
Acrobat metadata - Before print to PDF.
Acrobat metadata - After print to PDF.
If some other way to merge down metadata pops up, please let me know. Until then, while not a perfect solution this will have to work for now.
Thanks! |
