I am trying to make a page filling picture with a relative coordinate system. I used geometry to set the margings to 0pt and am drawing the picture using tikz. It almoast worked, but I can still see white at the left of the page and I can't explain why.
MWE:
\documentclass[12pt]{article}
\usepackage[a3paper,margin=0pt]{geometry}%No margins, A3 paper
\usepackage{tikz}
\usetikzlibrary{arrows.meta,backgrounds,positioning,shadings}
\begin{document}%
\begin{tikzpicture}[x=0.01\paperwidth,y=0.01\paperheight, very thick]%Coordinates relative to paper size
\fill[color = green!70] (0,0) rectangle (20,100);%(0,0) should be at the very left of the page, but it is't.
\fill[left color = green!70,right color =blue!50] (20,0) rectangle (26,100);
\fill[color = blue!50] (26,0) rectangle (72,100);
\fill[left color =blue!50, right color = red!60] (72,0) rectangle (78,100);
\fill[color = red!60] (78,0) rectangle (100,100);
\end{tikzpicture}%
\end{document}
Output:
I did not expect to see that white bar at the left of the page, since I thought I had specified the coordinates in such a way that (0,0) is at the very left of the page. What went wrong?
