Be aware of the difference between « scaled » and « sized ». You can try: \starttext \startMPpage draw externalfigure "dodo.png" sized 5cm shifted (-6cm,0) ; \stopMPpage \stoptext and try: \starttext \startMPpage draw externalfigure "dodo.png" scaled 0.018cm shifted (0,0) ; draw ((0,0) -- (5cm,0) -- (5cm,5cm) -- (0,5cm) -- cycle ) withcolor red ; \stopMPpage \stoptext In the second case, your image fits (approximately) in a 5cm square.

[NTG-context] no pagenumber depending of number of lines?
Hi, I got a difficult customer… If the last page of a chapter is less then half full (or has less than n lines), he doesn’t want a page number. Is there a simple solution to that request? Otherwise I delete the page numbers from the PDF...

[NTG-context] Arithmetic overflow on placing an external figure in MP
Bear with me, I still got no experience in MetaPost… I’m trying to place a pixel image on a MP page. According to the MetaFun manual this should work: \startMPpage draw externalfigure "mill.png" scaled 5cm shifted (-6cm,0) ; \stopMPpage And it works with mill.png (copied into my test dir), but with none of my other PNGs, I always get ! Arithmetic overflow. <*> ...xternalfigure "dodo.png" scaled 5cm shifted (-6cm,0) ; ; Uh, oh. A little while ago one of the quantities that I was computing got too large, so I'm afraid your answers will be somewhat askew. You'll probably have to adopt different tactics next time. But I shall try to carry on anyway. [1] 1 \startMPpage 2 draw externalfigure "dodo.png" scaled 5cm shifted (-6cm,0) ; 3 >> \stopMPpage 4 The same image file works with \starttext \externalfigure[dodo][height=8cm] \stoptext What’s wrong? The image is here: https://github.com/fiee/ConTeXt/raw/master/tshirts/img/dodo.png Greetlings, Hraban --- https://www.fiee.net http://wiki.contextgarden.net https://www.dreiviertelhaus.de GPG Key ID 1C9B22FD ___ 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 ___

In plain TeX you can get a slash through $\equiv$ with $\not\equiv$. When I do the same in ConTeXt, the slash next to the $\equiv$. Is there a way to get a not-equivalent sign in ConTeXt?
