Rotate an image - Anthony 14/6/2008

Rotate an image; again a lot more complicated than using Imagemagick.

  1. <?php
  2. // Set the path to the image to rotate
  3. $input_image = "House.jpg";
  4. //How many degrees you wish to rotate
  5. $degrees = 180;
  6. // Create the canvas
  7. $canvas = imagecreatefromjpeg( $input_image ) ;
  8. // Rotates the image
  9. $rotate = imagerotate( $canvas, $degrees, 0 ) ;
  10. // Save the image as output.jpg
  11. imagejpeg( $rotate, "output.jpg" );
  12. // Clear the memory of the tempory image
  13. imagedestroy( $canvas );
  14. ?>
