Hi,
Sorry for hitting the wrong mailing list. I have switched to the users
list.
The reason behind my question is the following:
I need to compare a server generated PDF with a template PDF by their
SHA-1 checksums. However this tag (here: IKOTCH) is dynamically
generated with each PDF generation on the server, i.e. two PDF
generation processes may produce two different tags. In order to compare
the file checksums I would like to set the tag to a fixed value as it
does not interfere with the rest of the document.
BR,
Robert

Hi,
why do you need to change that tag? IKOTCH+ as a prefix to the font
is used because you font is subsetted i.e. not all glyphs of the font
have been written into the PDF file. This is inline with the
specification.
As usage questions are discussed on the users mailing list may I ask
you to use that in the future?

Hello,
I have a PDF which embeds a TrueType font called UnicodeDoc. Within
the PDF I can see the following:
/BaseFont /IKOTCH+UnicodeDoc
Is it possible using PDFBox to change the tag value IKOTCH and if so
how? I know that this value may be different for other documents.
However I just need acces to this tagbut I cannot find the appropriate
way.
Sincerely,
Robert
