I know pdfium can edit PDF properties like Author, CreationDate, Subject, Title, and Producer etc.

Is there a way to edit "custom properties" with pdfium?

Hello,

What is a custom property? I assume this can be achieved with an appropriate dictionary.
Also you can try Pdfium.FPDF_SetMetaTex method.

Code:
Pdfium.FPDF_SetMetaText(document.Handle, "CustomTag", "custom value");

"Custom properties" meant attached images.
I would like to read and/or save these properties of pdf files.

The user manual of Pdfium.FPDF_SetMetaTex method says
>Currently, The tag can be one of "Title", "Author", "Subject", "Keywords", "Creator", "Producer", "CreationDate", or "ModDate".

Later I will try Pdfium.FPDF_SetMetaTex method with Custom Tag.

Thank you for advice.
I found that I could get custom properties using Pdfium.FPDF_GetMetaText, and set custom properties using Pdfium.FPDF_SetMetaText.

By the way, how can I save a PDF file that I changed using Pdfium.FPDF_SetMetaText?
I could not understand how to use "Pdfium.FPDF_SaveAsCopy".
