Re: [NTG-context] factor=fit images don't fit

Hello all,
I have to place a number of images into some given-size
frames in a layer. The images should be scaled
proportionally to fit into the frame. The code I'm working
with is:
\defineframed[framedimg][
frame=on,framecolor=elux,
background=color,
backgroundcolor=white,
width=\wdfig,
height=\htfigone,
offset=overlay,
]
\setlayer[figs][voffset=\nextfigvoff]{%
\framedimg{%
\externalfigure[#1][
factor=fit,
% maxwidth=\wdfig,
% maxheight=\htfigone,
% frame=on,
]%
}%
}%
where \wdfig, \htfigone are the frame size and \nextfigvoff
is the vertical offset which must be placed. I've tried
factor=fit, factor=max, but in both cases I get images which
cross the boundaries of the frame, mostly in the horizontal
direction. If I add the maxwidth/maxheight specification,
images don't get scaled at all.
I would expect factor=fit to scale the image in such a way
that the biggest direction fits into the enclosing box,
while factor=max would scale the image in such a way that
the smallest direction fits into the enclosing box. Instead,
in both cases the vertical direction is being fitted, with
no apparent consideration for the horizontal direction.
What am I doing wrong and what should I do to fix it?
Ok, I've tried studying the source and I really think that
the way factor scaling is computed is wrong. However, the
fix is nontrivial, and a somewhat thorough checking should
be implemented, with earlier check for the factor value
(fit, max, broad), since the logic selecting which dimension
to scale depends on the kind of scaling.
Anyway, I've found a temporary solutin to my problem by
using a very large value of scale=, coupled with appropriate
maxwidth and maxheight values.

[NTG-context] TABLE problems
Hallo,
I have two problems/questions with the following tables:
1. Should'nt all the columns be .2\textwidth, as in the last table?
2. Why expands column width to \textwidth in the second table?
Has to do with \type{} and/or color!
3. Why behaves table 1 (with \type{}) as table 3 (whitout \type{})?
