Around five months ago, I did not need to reset scale and factor.

I know. In the past I had to work around the fact that scale could not be 
set globally (because it was reset at each invocation). The current 
behavior (everything inherits from the global setting) is more predictable 
and easier to handle.


One complication with externalfigures is that scaling can depend on 
combinations (width, maxwidth etc).


... and the only way to figure out that dependence is to read the source 
code. At some stage I'll try to document how scale and factor work.

This is not much different from \setupframed .. when someone uses that 
one global all kind of derived mechanisms get affected. (In fact, there 
are many such global settings.)

Hi,

If scale option for a figure is set, \externalfigure does not honor the
width and the height parameters. For example

\externalfigure[cow][width=1cm, height=3cm, scale=750]

gives a figure which has the usual aspect ratio.

I know that settings scale=... along with width and height does not make
sense. But, in one of my project, I set

\setupexternalfigures[scale=750]

as that makes sense for most of the figures, and if I try to use

\externalfigure[cow][width=1cm, height=3cm]

then the aspect ratio of the figures does not change.

Not sure if this should be classified as a bug, but I am posting it here
in case anyone else encounters the same issue and needs to know how to
override this behavior:

\externalfigure[cow][width=1cm, height=3cm, scale=]


if needed you can use an abstraction:

\starttext

\defineexternalfigure[whatever][width=3cm,height=4cm]
\defineexternalfigure[another] [scale=500]

\externalfigure[cow]
\externalfigure[cow][whatever]
\externalfigure[cow][another]

\stoptext
