* [question] \clipping some data from a pdf @ 2020-01-28 23:27 Floris van Manen 2020-01-29 6:04 ` Henning Hraban Ramm 0 siblings, 1 reply; 3+ messages in thread From: Floris van Manen @ 2020-01-28 23:27 UTC (permalink / raw) To: ntg-context [-- Attachment #1: Type: text/plain, Size: 988 bytes --] Does anyone know? Using the latest LMTX, i try to clip some portion of an external pdf page, then resize that portion on top a new page. i use the \clip command. \starttext \scale[width=100mm, hwight=100mm]{\clip[width=150mm, height=120mm, hoffset=30mm, voffset=40mm]{\externalfigure[drawing.pdf]}} % incorrect \scale[width=100mm, hwight=100mm]{\clip[width=150mm, height=120mm, hoffset=30mm, voffset=136mm]{\externalfigure[drawing.pdf]}} % correct \stoptext I noticed that the voffset parameter *always* counts from the top/left of the external source. Also if the source has its origin defined at the lower/left corner. Is that intentional? It is confusing as when i place a rectangle on top of the clip i want to extract from the source pdf, the x,w,w,h of that rectangle will not match the parameter needed for the \clip command. Or does there happen to be some snazzy tool out there to get the coordinates of embedden images within a pdf? .Floris [-- Attachment #2: pEpkey.asc --] [-- Type: application/pgp-keys, Size: 2497 bytes --] [-- Attachment #3: Type: text/plain, Size: 493 bytes --] ___________________________________________________________________________________ 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] 3+ messages in thread

In case the "right" size of your image is defined as one of the PDF boxes (MediaBox, TrimBox, CropBox, ArtBox), you can set \externalfigure[drawing][size=art] (size=none/media/crop/trim/art).
