[Tex/LaTex] How to create a rectangle filled with image using TikZ

tikz-pgf

I want to create a rectangle with tikz and fill it with a predefined image.

For example the following line fill the rectangle with a color. How can I fill with my images instead?

\fill[color=sthlmRed] (0, 4cm) rectangle(\paperwidth, 0.5\paperheight);

Best Answer

The following uses TikZ image fill extensions from the tcolorbox package:

\documentclass{article}

\usepackage[skins]{tcolorbox}

\begin{document}

\noindent\begin{tikzpicture}
\path[fill overzoom image=example-image-a] (0,0) rectangle (\textwidth,4cm);
\end{tikzpicture}

\medskip

\noindent\begin{tikzpicture}
\path[fill stretch image=example-image-b] (0,0) rectangle (\textwidth,4cm);
\end{tikzpicture}

\medskip

\noindent\begin{tikzpicture}
\path[fill tile image*={height=3cm}{example-image-c}] (0,0) rectangle (\textwidth,4cm);
\end{tikzpicture}

\end{document}

[Tex/LaTex] How to draw a filled rectangle without a border using TikZ

The border of the rectangle is drawn because you are using the \draw command, which, by definition, draws the specified path (here the rectangle). The fact that you are adding the option fill=orange just tells TikZ that in addition it should fill the path with orange. Replacing \draw with \fill will do what you are expecting.

\documentclass{article}
\usepackage{tikz}

\begin{document}

\tikz \fill [orange] (0.1,0.1) rectangle (0.2,0.2);

\end{document}

As noted in the comments, another option is to use \draw [fill=orange,draw=none]. This amounts to telling TikZ to draw the path with an invisible color and fill it with orange, hence the result is the same. As drawing the path with an invisible color is maybe a little strange, it is perhaps more natural to use instead the general \path [fill=orange]. Note that \draw is simply a shortcut for \path [draw] and in a similar manner, \fill is a shortcut for \path [fill]. Similarly, you have the command \filldraw which is an abbreviation for \path [fill,draw]. In full generality, colors to use for either filling or drawing can be specified by replacing fill or draw by fill=color or draw=color in the options.

All these commands are documented in section 15 of the TikZ manual (and especially 15.3 and 15.4), with details and examples (accessible by the command texdoc tikz in a shell or here).

The answer Torbjørn points in the comments is related, but the circles there have always the same radius.

Another approach:

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{fadings,shapes.arrows,shadows}

\usepackage{xparse}

\tikzfading[name=arrowfading, top color=transparent!0, bottom color=transparent!95]
\tikzset{arrowfill/.style={#1,general shadow={fill=black, shadow yshift=-0.8ex, path fading=arrowfading}}}
\tikzset{arrowstyle/.style n args={3}{draw=#2,arrowfill={#3}, single arrow,minimum height=#1, single arrow,
single arrow head extend=.3cm,}}

\NewDocumentCommand{\tikzfancyarrow}{O{2cm} O{FireBrick} O{top color=OrangeRed!20, bottom color=Red} m}{
\tikz[baseline=-0.5ex]\node [arrowstyle={#1}{#2}{#3}] {#4};
}

% Parameters

\def\height{5}
\def\width{10}
\def\numpoints{500}
\def\maxpointwidth{1.75}

\begin{document}


\begin{tikzpicture}
\path (0,0) rectangle (\width,\height);

\foreach \point in {1,...,\numpoints}{
  \pgfmathparse{random()}
  \pgfmathsetmacro\xpos{\width*\pgfmathresult}
  \pgfmathparse{random()}
  \pgfmathsetmacro\ypos{\height*\pgfmathresult}
  \pgfmathrandom{0.1,\maxpointwidth}
  \let\pointwidth\pgfmathresult

  \node[circle,inner sep=\pointwidth pt,fill=blue!30] (point-\point) at (\xpos,\ypos) {};
}

\node [arrowstyle={\height cm}{black}{top color=orange,bottom color=yellow,shape border rotate=270}] at (\width/2,\height/2) {};

\end{tikzpicture}


\end{document}

This uses Fancy arrows with TikZ to create the gradient and the various parameters could be set in the preamble.

This could be probably an overkilling solution, but allows to achieve an higher customization:

   \node [arrowstyle={\height cm}{\arrowbordercolor}{top color=\arrowtopcolor, bottom color=\arrowbottomcolor,shape border rotate=270}, anchor=north] at (\width/2,\height) {};
  }
}

% that's just an alias for \node
\makeatletter
\def\drawdiagram{\tikz@path@overlay{node}}
\makeatother

\begin{document}

\begin{tikzpicture}

\end{tikzpicture}

\begin{tikzpicture}[height rect=4,width rect=8,
 num points=600,
 point style={/tikz/point style type/vertical shade},

\drawdiagram[random point diagram] at (0,0) {};

The first example with the default values gives the previous picture, while the second customized example:
