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=]
Aditya

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

I actually use these abstractions, but with the default value also set.
That's the whole point of having the defaults, right? So, my current
solution is:
\setupexternalfigures[scale=750, factor=max, maxwidth=\textwidth, maxheight=\textheight]
\defineexternalfigure[grid]
[width=0.55\paperwidth, height=0.33\paperwidth, scale=, factor=]
Around five months ago, I did not need to reset scale and factor.

The code now uses the new inheritance mechamisn and in mkii external
figures had a whole bunch of (sometimes tricky) resets. Some were reset,
some not. One complication with externalfigures is that scaling can
depend on combinations (width, maxwidth etc).
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.)

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.

... 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.
