Adobe claims Intellectual Property rights over the Adobe PDF
specification and we aim to ensure that those rights are
upheld.
When you install ABCpdf you accept the ABCpdf license agreement.
Part of the agreement specifies that you must abide by the
conditions of use for PDF set down by Adobe and detailed in the
Adobe PDF Specification.
For full details you should see the specification. However in
summary, Adobe permits you to write software to create, display and
manipulate PDF documents.
This permission is conditional on the basis that your software
should respect the permissions and permission controls embedded
within existing PDF documents.
These permissions do not necessarily make sense within the
ABCpdf framework. For example the concept of an encrypted document
which bars the user from filling in form fields makes sense if
there is a user. However ABCpdf is a component and so is removed
from the final user.
You should ensure that when you create software which an end
user may operate that your software respects these types of
permissions. You are legally bound to do this both by the ABCpdf
license agreement and also by the Adobe conditions of use.
