But notice that if it did work, the sizes of TrimBox and BleedBox would be based off printpaperwidth and printpaperheight. I need them to be based off paperwidth and paperheight (for my documents all have printpaperwidth – paperwidth ≠ printpaperheight – paperheight). (Apologies, I initially replied to just you and not the list as well.)

Hi Jack, there seems to be a bug in ConTeXt (both in MkXL and MkIV). From this code: \setuplayout [cropoffset=15ex, trimoffset=20ex, bleedoffset=25ex, artoffset=30ex] \starttext \input zapf \stoptext I get the relevant code: /CropBox [ 0 0 595.2756 841.8898 ] /MediaBox [ 0 0 595.2756 841.8898 ] /TrimBox [ 0 0 595.2756 841.8898 ] I think it might be a bug that prevents this from working properly. (ArtBox is simply disabled.) Hans, could you check this? Many thanks for your help. Pablo PS: sorry for having changed the subject, Jack. It intends only to increase visibility about code that may need to be improved. -- http://www.ousia.tk ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 7+ messages in thread

It would be good if cropoffset, trimoffset etc. took two dimensions, one for the x direction and one for the y direction, instead of one for both.
