watermarktext – Set the text to use as a Watermark

Description

<watermarktext  $content [ $alpha ] />

Set the text to use as a Watermark. The watermark is a semi-transparent background printed on each page, used for text such as “DRAFT”. The watermark will be added to each page when the Footer is printed if the variable showWatermark is set to 1 or TRUE

Parameters

$content

This parameter defines the text to use for the watermark.

$content cannot contain any of the characters: < > & ‘ or “ and must use the appropriate HTML entities e.g. <watermarktext content=”Brian&#039;s document” />  It is recommended that you use htmlspecialchars(‘Content’, ENT_QUOTES) for this.

If the text is blank, it will clear the watermark text, so nothing appears.

DEFAULT: BLANK

$alpha

This parameter defines the transparency value (alpha) to use for the watermark: either text or image. The Value should be between 0 and 1.

DEFAULT: 0.2
