[Tex/LaTex] Watermark image

graphicstutorialswatermark

Please note I'm new to LaTeX so don't know much about it (yet). I've looked on-line about how to add a watermark image but don't know how to do it. I've seen sites that show something about it but they seem to be aimed at people who know how to add extra packages, something I don't know how to do (yet).

Does anyone know of a site or tutorial that takes 'newbies' through the process on a step by step basis? I will need o have text easily readable on the page so the colors as I want to have it centered on the page both horizontally and vertically but automatically adjusted to fill the page to the margins up but keep the aspect ratio of the original image.

How about a simple example like the following? Create the image file, name it test.png, then compile the document via pdflatex.

\documentclass{article}
\usepackage{graphicx}
\usepackage{draftwatermark}
\SetWatermarkText{\includegraphics{test.png}}
\begin{document}
Some text.
\end{document}

There is also the eso-pic package, but I have not used it myself.

[Tex/LaTex] How to write multiple lines as watermark?… and images with transparency

Using the draftwatermark package, you can use a \parbox, or a minipage, to have the text spanning several lines:

\documentclass{article}
\usepackage[a6paper]{geometry}
\usepackage{draftwatermark}
\usepackage{url}
\usepackage{lipsum}

\SetWatermarkText{\parbox{12cm}{%
  Mika Ike \\
  \url{mikaike@mikaike.mikaike} \\ 
  At My house}}
\SetWatermarkScale{.5}
\SetWatermarkColor{red}

\begin{document}

\lipsum[4]\lipsum[4]
\lipsum[4]\lipsum[4]

\end{document}

enter image description here

In the case of opacity for images, the draftwatermark package apparently doesn't provide many possibilities.

As an alternative, I'd suggest you to use the background package; since this package internally uses TikZ, you can easily control the attributes (opacity, color, position, etc.) for the background material. A little example:

\documentclass{article}
\usepackage[a6paper]{geometry}
\usepackage[scale=2.5,opacity=1,color=red]{background}
\usepackage{url}
\usepackage{varwidth}
\usepackage{lipsum}

\backgroundsetup{
contents={\begin{varwidth}{8cm}{%
  Mika Ike \\
  \url{mikaike@mikaike.mikaike} \\ 
  At My house}\end{varwidth}}
}

\begin{document}

\lipsum[4]\lipsum[4]
\lipsum[4]\lipsum[4]

\end{document}

The varwidth environment was used to have a box of adjustable width allowing multiple lines of text; a minipage or a \parbox could also have been used instead.

And, using an image:

\documentclass{article}
\usepackage[a6paper]{geometry}
\usepackage[scale=1,opacity=0.75,angle=0]{background}
\usepackage{url}
\usepackage{varwidth}
\usepackage{lipsum}

\backgroundsetup{
contents={\includegraphics[height=\textheight,width=\textwidth,keepaspectratio]{ctanlion}}
}

\begin{document}

\lipsum[4]\lipsum[4]
\lipsum[4]\lipsum[4]

\end{document}

[Tex/LaTex] Blur the whole document and add a demo watermark on each page

Using Gonzalo's code with tikz

\documentclass{article}
\usepackage[printwatermark]{xwatermark}
\usepackage{xcolor}
\usepackage{tikz}
\usepackage{lipsum}

\newsavebox{\waterbox}
\begin{lrbox}{\waterbox}
\begin{tikzpicture}[remember picture]
 \fill[draw,white,opacity=0.7] ([shift={(2,2)}]current page.south west) rectangle (current page.north east);
 \node[text width = 2in,rotate=-45] at ([shift={(10mm,10mm)}]current page.center) {Some text here that appeas dark and rest is blurred};
\end{tikzpicture}
\end{lrbox}

\newwatermark*[allpages,angle=45,scale=3,xpos=0,ypos=0]{\usebox{\waterbox}}

\begin{document}

\lipsum[1-2]
\begin{figure}[!ht]
\centering
\includegraphics[width=3cm]{example-image-a}
\end{figure}
\lipsum[1-2]
\lipsum[1-20]
\end{document}

enter image description here

You have to adjust the position of text in

\node[text width = 2in,rotate=-45] at ([shift={(10mm,10mm)}]current page.center) {Some text here that appeas dark and rest is blurred};

Now with eso-pic.

\documentclass{article}
\usepackage{tikz}
\usepackage{lipsum}

\newsavebox{\waterbox}
\begin{lrbox}{\waterbox}
\begin{tikzpicture}[remember picture]
 \fill[draw,white,opacity=0.7] ([shift={(2,2)}]current page.south west) rectangle (current page.north east);
 \node[rotate=45,text width = 0.5\textwidth,scale=2,anchor=center,align=center] at ([shift={(0.6\paperwidth,1cm)}]current page.west) {Some text here that appeas dark and rest is blurred};
\end{tikzpicture}
\end{lrbox}

\usepackage{eso-pic}
\AddToShipoutPictureFG{%
\usebox{\waterbox}
}

\begin{document}

\lipsum[1-2]
\begin{figure}[!ht]
\centering
\includegraphics[width=3cm]{example-image-a}
\end{figure}
\lipsum[1-2]
\lipsum[1-20]
\end{document}
