Hi, according to the wiki the \externalfigure key “factor” has the options: max: aspect ratio is kept, the image is scaled to the bigger (oversized) variant fit: aspect ratio is kept, the image is scaled to the smaller (fitted) variant In the following example I expect the third image to have a width of 4cm and a height of 4cm. However, both values are 3cm. The aspect ratio is kept, but “max” and “fit” behave the same. \startbuffer [img] \useMPlibrary [dum] \startTEXpage \externalfigure [dummy] [width=5cm,height=5cm] \stopTEXpage \stopbuffer \ctxcommand{runbuffer("img", "img", true)} \starttext \externalfigure [\jobname-img] [width=3cm, height=4cm] \blank \externalfigure [\jobname-img] [factor=fit, width=3cm, height=4cm] \blank \externalfigure [\jobname-img] [factor=max, width=3cm, height=4cm] \stoptext Is this a bug or am I misunderstanding the wiki? Anyhow, is there a clean solution to keep the aspect ratio and scale the image to whichever value is larger? Marco
