imagerotate
(PHP 4 >= 4.3.0, PHP 5) imagerotate -- Rotate an image with a given angle
Descriptionresource 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.
Пример 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);
