I am drawing a block diagram with TikZ. While everything is working like a charm, I cannot draw in the background. My code is
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes,snakes,automata,backgrounds,petri,shadows}
\pgfdeclarelayer{background}
\newcommand{\eng}[1]{\latintext#1\greektext}

I have forgoten to add \usetikzlibrary{backgrounds}
in main's preamble… When I did something really weird happened… Rectangles are not filled with color, background rextangles are not filled with color as well and you can see some shading float around page.
I don't have a clue on what's going on…
Best Answer
You have to tell TikZ in what order to stack the layers via
\pgfsetlayers{<layers>}
, where<layers>
is a comma separated list of layers from back to front. All commands which are not inside apgfonlayer
environment will be assigned to the layermain
which is always defined. To have such commands on the right layer,main
should always appear in the<layers>
specification. TikZ will not throw an error when not using\pgfsetlayers{<layers>}
, however it will act rather strange and leave out commands for most layers. When leaving out the\pgfsetlayers{<layers>}
it didn't matter in what orderbackground
orforeground
were declared or used, thebackround
was always shown and theforeground
never, which is really strange. So I guess the advice is always to remember writing\pgfsetlayers{<layers>}
as otherwise strange results may occur.Code
