imagerotate -- Rotate an image with a given angle

Syntax

resource imagerotate ( resource src_im, float angle, int bgd_color )

Rotates the src_im image using a given angle in degrees. bgd_color specifies the color of the uncovered zone after the rotation.

The center of rotation is the center of the image, and the rotated image is scaled down so that the whole rotated image fits in the destination image - the edges are not clipped.

Example 1. Rotate an image 180 degrees

This example rotates an image 180 degrees - upside down.


// File and rotation
$filename = 'test.jpg';
$degrees = 180;

// Content type
header('Content-type: image/jpeg');

// Load
$source = imagecreatefromjpeg($filename);

// Rotate
$rotate = imagerotate($source, $degrees, 0);

// Output
imagejpeg($rotate);

Note: This function is only available if PHP is compiled with the bundled version of the GD library.
