Sorry, Hans, I copied the wrong sample (value for "width" in
"\setupinteractionscreen" should read "fit" instead of "max"):


Here are the boxes (using current latest from today [2023.03.06 14:48]):

  3 0 obj
  [ 0 0 595.275590072 841.88975789 ]

  7 0 obj
  [ 0 0 968.199847496 841.88975789 ]

Page 1 (object 4) uses object 3 as /CropBox, /MediaBox and /TrimBox.

Page 2 (object 7) uses object 3 as /MediaBox and object 7 as /CropBox
and /TrimBox (I have just discovered it).

I think it is better to avoid having a page with a /CropBox larger than
its /MediaBox.

But I’m afraid that it is wrong to have a /TrimBox larger than the
/MediaBox for the same page.

I hope it is clear now. Sorry for the mistake in copying the wrong sample.

Many thanks for your help,
