Hangaround is a very robust command and works in more cases than
\placefigure[left] but you have a conflict with the \item command
which place the itemize symbol before the following text which

Dear ConTeXt list,
I apologize for digging up an old thread. I was searching for
\starthangaround[right] and found this thread. I tried the code that
Wolfgang gave in this thread but I guess something has changed since then,
because it does not work with latest minimals. Would it be possible to get
(a working) version of \starthangaround[right]? I think it even would be
nice to have it in the core.
As a minimal nonworking example, see the email from Wolgang in this thread.
With best regards, Mikael

Re: [NTG-context] Q about hangaround commands
Hi Mikael,
The example given by Wolfgang works fine for me with mkii, but not in mkiv:
probably something has changed in mkiv, for example the way [scale=500] must be
used in mkiv.
Best regards: OK

Thank you for the quick fix. It works for the minimal example, but it
fails in my document. Defining custom float types seems to break the auto
reordering.
New defined floats are still wrongly enumerated. Is there a workaround for
this?

[NTG-context] drops module (draft)
Hi all,
a first version of the 'drops'-module (MkIV only) is available at
https://www.wuala.com/indiego/public/ConTeXt/drops/?key=caiCGLasLFmJ
Taken from the included documentation..
[..]
'drops' is a small extension for ConTeXt, that allows you to add drop
shadows to rectangular regions (so called boxshadows). A working
installation of ImageMagick (IM) is required to create the shadow

shadow (or frame) types and it's source is a good starting point for
your own experiments.
This is a first draft, but most things work quite stable. If you want to

*You need a recent version of ImageMagick for this module.*
6.7.8-2 to 6.8.0-7 (wrong version info 6.8.0-6): used here, should work
6.7.6-0 or lower: will fail due to incompatibilities
7.0.0.0 alpha: untested ('magick' is used instead of 'convert')
Tested on Windows7 64bit and Debian 6.0.5-i386 (IM compiled from source)
Happy TeXing!

Nice.
The module would be cleaner with a MkIV rewrite and I would drop the option
to accept each module parameter with \usemodule.
I would also create a new namespace for the \setupdrops command because
currently it uses the “module” namespace.
\def\dosetupdrops[#1]%
{\iffirstargument\getparameters[\??module drops:][#1,{\c!setup=}]\else %
never parameter 'setup'
\ctxlua{thirddata.drops.resetdrops()}\fi} % reset all parameters to their
default, when no argument is given

It is. I use MetaPost to draw the shadows using the shading
mechanism:
withshading(circular, urcorner bottom_left, urcorner bottom_left, radius, 0)
withfromshadecolor \MPcolor{c:transparent}
withtoshadecolor col;
and it works well if placed in an overlay. However, I did not manage
to get it working in TikZ, it could not display shadings to
transparent colours (which is very handy for slides where the
shadings might overlay graphics with a non-uniform colour).
Since you are the PDF expert, I am interested in knowing why you
choose to go the ImageMagic route.
From my experience shadows made from MetaPost shadings (which uses
PDF shadings, I assume) are quite low level. It's harder to get the
angle, distance and shadow size correctly implemented. I think the
ImageMagick shadings are more high level and ready to use.

I always thought that shadows were possible to do in PDF (after all TikZ
does it using some type of PDF primitives). Since you are the PDF
expert, I am interested in knowing why you choose to go the ImageMagic
route.
Some tricks are possible with functions that repeat bitmap patterns in
clever ways but I lost the code that does it. If Peter can tell us what
graphics are needed we can also make them directly as the img library
has that possibility (we use it in mojca's gnuplot module)
Anyhow, as you are the math magician, here's a start:
\starttext
\startluacode
local format = string.format
function document.TestBitmap(nx,ny)
local r = { }
local s = 1/nx
for i=1,ny do
local c = { }
for j=1,nx/2 do
c[#c+1] = format(%02x,j*s*255)
end
for j=nx/2,1,-1 do
c[#c+1] = format(%02x,j*s*255)
end
c = table.concat(c,,1,nx)
r[#r+1] = c
end
r = table.concat(r,\r,1,ny)
print(r)
context(r)
end
\stopluacode
\startMPcode
draw
textext(\bitmapimage[x=100,y=100,color=gray]{\ctxlua{document.TestBitmap(100,100)}})
xsized 10cm ;
\stopMPcode
\stoptext
So, what's needed is some edge related jugling.

Yes. Of course we can make shading more clever, but to be honest I never

The argument for the command keys has to be a macro with two parameters,
the first parameters contains the formatted header and the second argument
the formatted content of the environment.
