tikzposter
I have a poster in tikzposter.
Now I would like to place a box at the bottom of the page.
It should be as wide as the complete poster.
It should "touch" both the sides of the poster and the bottom of the poster.
The box should not replace the title – I need that too.
How can this be done?
Thank you for your time.
I ended up solving it myself. Below is the code I used; if you put it in myposter.sty then use \usepackage[colalign]{myposter} to enable the alignment.
It works by saving the natural heights of all columns into the aux file, along with how many blocks there are. Then next compilation, for each column, it looks at the difference between the stored height and the maximum stored height, divides that by the number of blocks, and adds that much padding inside each block (at the top and bottom.)
\usepackage{letltxmacro}
\usepackage{ifthen}

\DeclareOption{colalign}{
\my@colaligntrue

After issuing
\geometry{paperwidth=42in, paperheight=60in}
you have to recalculate \TP@visibletextwidth and \TP@visibletextheight. So, after that line, add
\makeatletter
\setlength{\TP@visibletextwidth}{\textwidth-2\TP@innermargin}
\setlength{\TP@visibletextheight}{\textheight-2\TP@innermargin}
\makeatother
MWE:
\RequirePackage[demo]{graphicx} % remove this line in your document
\documentclass[17pt, a0paper, landscape]{tikzposter}
\geometry{paperwidth=42in, paperheight=60in}
\makeatletter
\setlength{\TP@visibletextwidth}{\textwidth-2\TP@innermargin}
\setlength{\TP@visibletextheight}{\textheight-2\TP@innermargin}

The whole
tikzposteris essentially onetikzpicture. Further, the class defines a coordinatebottomleftat the lower left corner of the paper, so you could probably just add something likejust before
