Scaling figures

Scaling figures

[Jaroslav Snajdr]

Hello,

I write a document that contains a lot of figures - screenshots. And I
have a problem with their scaling. They look the best if I write

\externalfigure[window.png][scale=3000]

However, some screenshots are so large that they are wider that the
paper. So, what I need is to tell context to use scale=3000 most of the
time, but if the figure would be wider than \textwidth, just scale the
figure to \textwidth.

\setupexternalfigures[xmax=\textwidth]

doesn't work for me. Any clue?

Thanks,
J. Snajdr

\externalfigure[window.png][scale=3000,maxwidth=\textwidth,maxheight=\textheight]

or (dirty untested trick):

\useexternalfigure[screenshot][screenshot][scale=3000,.....]

\externalfigure[window.png][screenshot]

\externalfigure[window.png][width=\textwidth]

isn't quite as automatic as you want but works for my figures.

in your case:

\externalfigure[..][maxwidth=\textwidth,maxheight=.8\textheight,factor=max]

may work out well

factor or b/hfactor in that case will scale to the available size
