Setting these parameters in ImageEnView 14.2.7:
IO.Params.PDF_Creator := 'My Application';
IO.Params.PDF_Producer := 'ImageEn PDFium';


PDF created by SaveToFilePDF shows these Document Properties in Adobe Acrobat Reader 25.1.20937.0:



Questions:

1. Shouldn't Adobe PDF Producer be "ImageEn PDFium"?

2. Where is 'My Application' in Adobe Document Properties?

The ImageEn Documentation says:

TIOParams.PDF_Creator
Specifies the application that created the original document.

TIOParams.PDF_Producer
Specifies the application that converted the image to PDF.

Yes, but please see the note, "This field is not saved if TIEGlobalSettings().PDFEngine is ieenDLL (PDFium), or using the IEVision PDF Generator". I'll improved the documentation to make it a bit clearer.

Unfortunately, at this time, PDFium does not provide a method to set meta-data.

Hi Nigel, can you please improve SaveToFilePDF to:

1. Correctly save the PDF_Producer field
2. Correctly save the PDF_Creator field to the name specified in PDF_Creator (the name of the Application)

Maybe it would be a good idea to implement this automatically in SaveToFilePDF, without requiring the PDF_Producer and PDF_Creator metadata fields to be specified explicitly unless they are expressly specified?

Thank you!

Hi Peter

Until PDFium adds support for writing meta-data, it won't be available for the ieenDLL engine. However, you can just use the native PDF engine which supports meta-data:

IEGlobalSettings().PDFEngine := ieenNative;
