So what you are saying is this:
If i decide to do any transformation on my image or other element this will
not work correctly?
I am aware i do have to adjust the matrix, but i was not aware i did have to
alter the bbox.(although i do understand why)

It's not the resources that are the issue - you are correct, you
could leave them alone...
It's the matrix and BBox that are most important, as those values are
actually used when processing the content. So if you change the size
and/or transformation of the content inside the XObject - it

Why is this important?
Suppose that your original XObject uses a font Helvetica,

Provided that you replace the ENTIRE object (with all associated
elements in the dictionary), then it should be fine to replace Form
XObjects as well.

In my case I know that there will either be Xobject of the subtype image or

I'm sorry, I hardly ever use Acrobat and I don't have Illust
You can't influence either - they will do what they want when
authoring. So you'll need to write more complex code to deal with
the problem...
Remember that XObjects can either be simple raster images OR complex
"mini-PDFs". The replacement works fine for raster images, but not

I have to admit i am not aware how one can influence the creation of an
XObject with a explicit /OC entry using Acrobat or Illustrator.
Are you able to help me with pointers on this issue?
Also I had a look at your receipe for finding the object's corresponding

I have a counter-question
OK, thanks for the great help.
I fully understand your concern when it comes to the possibility of
destroying the output, however in our case we have full control of the
original pdf that will be read.
The idea is that someone with esthetics produce a nice pdf.
This pdf will then be opened and imag

Each xobject in my pdf is placed on its own layer.
The strange thing is that i am not (allthough i have read about this before)
able to find a reference to the oc in either of the objects streams.
The pdfs are genreated from Adobe Illustrator.
Any idea why the oc reference is left out?
Btw i do me
