Title Slide

Learning Objectives

• Create and customize watermarks using the draftwatermark package
• Control watermark visibility on specific pages
• Use the eso-pic package for watermarking over the images

System Requirements

• Linux Mint OS version 21.3
• Texworks version 0.6.6

Pre-requisites

Code files

The following code files are required to practice this tutorial:

1. draftwatermark-eg.tex

2. Free-Stock-Photos.jpg

These files are provided in the Code Files link of this tutorial page.

\usepackage{draftwatermark}

Click the green Typeset button and show the output

Here is the output

Default watermark DRAFT is printed across all the pages

uncomment line 8

Run the code and show the output

uncomment line 8.

Let’s run the code.

The watermark is printed only on the first page.

uncomment line 7, 12

Run the code

Highlight:

line 12

uncomment lines 7 and 12.

Run the code

Watermark Draftcopy is printed across all the pages.

Observe the options given in the \DraftwatermarkOptions command.

uncomment line 27

Run the code and show the output

Cursor on the text keyword.

Cursor on the changed watermark.

uncomment line 27.

Run the code

text keyword in the command changes the watermark text.

Here the watermark changes to Sample.

Run the code and show the output

color keyword changes the watermark colour.

Here it changes to blue

We can also use values like [gray]{0.5} or [rgb]{1, 0, 1}.

That is by name and its strength or with the rgb option.

For that we have to load \usepackage{xcolor} in the preamble.

Run the code and show the output

Run the code

fontsize keyword changes the watermark’s fontsize.

Run the code and show the output

Run the code

Here is the output.

hpos keyword

changes the horizontal position of the watermark.

Run the code and show the output

Run the code

Here is the output.

vpos keyword changes the vertical position of the watermark.

Run the code and show the output

Run the code.

angle keyword in the command changes the angle of the watermark

Here it changes to 60 degrees.

Run the code and show the output

Run the code

Stamp keyword is set to true or false.

Here false makes the watermark vanish from all the pages.

uncomment line 34

Run the code and show the output

Highlight:

Highlight lines 27 to 33 and then Highlight line 34.

Highlight the text EduPyramids in the code.

Uncomment the line 34

Run the code.

Notice that all the options are given in a single line of code.

Here watermarking text is EduPyramids.

Now, let us see how to get the watermark on top of the image too.

Highlight lines 37 to 43

Highlight Line 46

We use this package to get a watermark on top of the images.

In lines 37 to 43 we define a new command called MyWatermark.

This command defines the watermark’s text colour to blue and the text to Confidential.

Line 46 instructs the compiler to ship out every page with the watermark on foreground.

Cursor on the Output

Now we see the watermark on the image too.

Watermarking it with blue colour and with the text Confidential.

Summary

In this tutorial, we have learnt to:

• Create and customize watermarks using the draftwatermark package
