Floats in Columnsets

Floats in Columnsets

[Michal Kvasnicka]

Dear Sir Hagen,

I know you are writing the complete manual for the columnsets, nonetheless I 
dare to bother you in advance. What are options for telling floats to what 
column, line and page they should go? I hade some examples from you, but I 
lost it when my harddisc crashed. Can you help me?

Many thanks and greetings,
Michal Kvasnicka

\placefloat[btrl]{caption}{figure}

btlr == flush from bottom to top starting in the left column going to the 
right

you can deduce the rest of the flushers from this;

then there is 'here' fixd' as well as 'fxtb:2' for something in the second 
column as well as fxtb:2*3' for something in column 2 row 3

that's about it; spanning happens automatically (also over spreads if 
needed) (there are special commands for spreads and so)

Many thanks. It's wonderfull. I'm looking forward to the day when columns 
could be ballanced. Then I'll reset our church bulletin to it and will use 
much more pictures.

With best regards

These things have to do with the fact that captions should snap on the 
grid; however, you can influence things by setting the grid parameter for a 
float instance. More on that in details.pdf.

Also the next version has a grid key in \externalfigure which can snap 
scaling to combinations of (height div lineheight) * lines + [0,1] * depth 
+ [0,1] * height which in combination with the float grid options can give 
you whatever you want.

Hans

PS. Grid snapping introduced quite some border cases and a lot of effort 
has gone into providing control over that. An associated new feature is a 
yet to be documented  and for the moment experimental graphic/background 
synchronization mechanism.

It appears as though \placefigure doesn't work very well with columnsets
if the size of the floats isn't an exact multiple of the underlying
grid. More precisely, \placefigure and friends, when used with any of
the *tb and tb* options (tblr, tbrl, lrtb, rltb, fxtb) snap the bottom
of the figure to the grid rather than the top. Of course, that means
that most of the time figures will not be aligned at the top. (See below
for an example.)

Does anybody know of a fix or workaround for this problem?
