Hello list, I want to draw lines on a page. I want to pass my line coordinates as a percent of \width or \textheight, rather than as millimetres. So that if I change the page size I don't need to change the coordinates.
The MWE below compiles but the pdf does not have any lines drawn on it. Is there a way of doing calculations on the coordinates for the draw using ConTexT variables like \textheight? Thank you, Peter Hopcroft ------ \starttext Some text \startMPcode pickup pensquare scaled 1pt; draw (0mm,0mm)--(0mm,\textheight) withcolor red \stopMPcode More text \startMPcode pickup pensquare scaled 1pt; draw (0mm,0mm)--(0mm,50mm) scaled \numexpr\textheight/50mm\relax \stopMPcode \stoptext ------ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : {listname} / https://mailman.ntg.nl/mailman3/lists/{list_id} webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________
