Hi Mark,
What I would probably do (again) is:

1 leave out the float dimension from the setup and use something like
\definefloat[figure][figures]
\setupfloat[figure][location=,spacebefore=,spaceafter=,sidespacebefore=,sidespaceafter=] or whatever you want in this respect

2 collect in a separate .tex-file, to be input in your document .tex-file, all figure-data in the form 
\useexternalfigure[Fig1][YourFigure1.png][width=.x\textwidth]%  etc

If you want a different uniform figure width you can then easily replace ijn this file all width=.x\textwidth by width=.y\textwidth.

3 In your document .tex-file use 
\placefigure[here][Fig1]{Title}
{\externalfigure[Fig1]}  

This will probably give you optimal flexibility.

I hope it helps.

Best regards,
Robert Blackstone

Thanks Aditya, that's very helpful and things make more sense now. Is this
stuff documented somewhere or did you consult the source code?

\setupfloat[figure] sets the values of \startplacefigure (and 
\placefigure), and not for \externalfigure. The width value for 
startplacefigure is not used anywhere.

The default value of \setupfloats[width=...] is used when the float box is 
empty. So, the only scenario where the value of \setupfloats[width=...] 
will matter is the following:

\starttext
\setupfloats[width=2cm]
\placefloat{}{}

\setupfloats[width=10cm]
\placefloat{}{}
\stoptext

Thanks all for your responses.

\defineexternalfigure looks like it does something very close to what I
wanted. Googling it brought me to a mailing list thread where a question
similar to mine was asked, so for future reference:
http://www.ntg.nl/pipermail/ntg-context/2012/069446.html.

So I guess my problem is resolved, but I'd still like to understand better
why my earlier solution of doing

\setupfloat[figure][width=2cm]

didn't set a default for later instances of \placefigure. I feel like I
might be missing some aspect of the ConTeXt philosophy, or I'm misreading
the manual, or it's just a bug...?

Hi Mark,
You can use \defineexternalfigure as in the following example.

\defineexternalfigure[whatever][width=2cm]
\starttext
\placefigure{}{\externalfigure[picture.png][whatever]}
\stoptext

Sorry, I should have mentioned I was able to work around it by doing
exactly that, but I'd rather not have to edit all the \placefigure
instances if I decide to change the width.

Also I'd like to use a different default width for graphics, so
\setupexternalfigures[width=XXXcm] wouldn't work well either.

I realize I could define my own macros or something to solve this, but I'm
just puzzled that setting width in \setupfloat[figure] doesn't work. Am I
reading the manual wrong, or is is just not implemented yet or something?
(honest question)

Thanks for your response,

Mark

just

\placefigure{}{\externalfigure[picture.png][width=2cm]}

How does \setupfloat work?

[Mark Szepieniec]

[-- Attachment #1.1: Type: text/plain, Size: 537 bytes --]

I'm trying to set a default width for figures with \setupfloat. However,
the command doesn't seem to be picking up the width specification, even
though the manual indicates it accepts a width= argument:

\setupfloat[figure][width=2cm]

\starttext

\placefigure{}{\externalfigure[picture.png]}


\stoptext


picture.png just gets inserted at its native size, rather than scaled to
have the specified width. What am I doing wrong? (setting minwidth and/or
maxwidth doesn't seem to work either)

Thanks in advance for any assistance.

Mark
