PDFRotate

PDFRotateTrait

This script allows to perform a rotation around a given center.

The rotation affects all elements which are printed after the method call (with the exception of clickable areas)

Remarks:

• Only the display is altered. The GetX() and GetY() methods are not affected, nor the automatic page break mechanism.
• Rotation is not kept from page to page. Each page begins with a null rotation.

Requires

Require use of PDFTransformTrait

Usage

The method to set a rotation is:

/**
 * Prints a character string with rotation
 *
 * @param float $x Abscissa of the origin.
 * @param float $y Ordinate of the origin.
 * @param string $txt String to print.
 * @param float $angle Angle in degrees.
 * @return void
 */
PDFRotateTrait::RotatedText(float $x, float $y, string $txt, float $angle);

/**
 * Puts an image with rotation
 *
 * @param string $file Path or URL of the image.
 * @param float $x Abscissa of the upper-left corner.
 * @param float $y Ordinate of the upper-left corner.
 * @param float $w Width of the image in the page.
 * @param float $h Height of the image in the page.
 * @param float $angle Angle in degrees.
 * @return void
 */
PDFRotateTrait::RotatedImage (string $file, float $x, float $y, float $w, float $h, float $angle)
