Q: Using CosEdit (
http://www.pdftron.com/pdfcosedit) can I delete an
entire dictionary object?
-----
A:You can use CosEdit to delete object from existing PDF documents.
The way this works is by deleting all links to a given object in the
right side view. For example, to delete a font from a given document
you would navigate to the font dictionary in the page resource (e.g.
trailer/Root/Pages/Kids/0/Resources/Font) and would select and delete
the object. If there are no other outstanding references to the object
the dictionary would be deleted during ‘Save As operation’.
