\startchapter[title={Grid trickery}]
In this manual we pay quite some words on ways to snap your content on a grid.
When dealing with grids, we often run into conflicting situations where we have
to make the best of it. Let's again deal with an aspect of graphics.
One of the strong points of \TEX\ is that it can deal with graphics
automatically, which means that you seldom have to tweak dimensions or placements
unless \unknown\ you're dealing with grids. In that case you need to make sure
that the height of graphics consistently match the height of lines (or multiples
of lines). It is for this purpose that the graphic inclusion macro has a \type
{grid} entry.
We will illustrate its usage using a dedicated figure class where we have set the
space between figure and caption to zero.
\startbuffer
\definefloat[tightfigure][tightfigures][figure]
\setupcaption[tightfigure][inbetween=]
\stopbuffer
\typebuffer \getbuffer
The \type {grid} parameter controls rounding of the height of a graphic in the
following way:
\starttabulate
\NC \type {yes} \NC safe rounding to an equal number of lines \NC \NR
\NC \type {fit} \NC tight rounding to an equal number of lines \NC \NR
\NC \type {height} \NC same as \type {yes} but incremented by linedepth \NC \NR
\stoptabulate
On the next pages we demonstrate the effects of these settings. At the bottom of
a page we show the placement commands. On the last pages we've hidden the
captions with:
\starttyping
\setupfloat[tightfigure][default={here,none}]
\stoptyping
As you will notice, the \type {height} option is handy when the caption is
positioned directly under the graphic.
