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
