[***SPAM***] Provide showgrid as a PDF layer

[Jan Tosovsky]

Dear All,

it would be nice to have a possibility to interactively disable/enable a
grid rendered via \showgrid command. Whereas this grid is helpful for
debugging, it disturbs when the page is evaluated as the whole. Using layers
could make this process more efficient (not requiring to generate both
variants).

I've noticed something like this is already implemented for the body area
(visualizer vbox layer).

Or is there any option for this already?

Thanks, Jan

Wow, thanks! 

So to show grids as a layer at least \showlayoutcomponents must be set as
well. To be honest, I'd expect displaying the grid directly without this
dependency...

Anyway, it works fine in Adobe Reader.

\setupinteraction[state=start]
\showgrid  \showframe \showmakeup \showlayoutcomponents

\starttext
     \input tufte \placefigure{}{}
\stoptext

but you need a viewer that supports layers (can turn them on and off)
