ROTATE(1)						      General Commands Manual							 ROTATE(1)

NAME

       rotate - Rotate, mirror, and transpose JPEG images (losslessly whenever possible)

SYNOPSIS

       rotate { options } file [ file ... ]

DESCRIPTION

       rotate  is  a  convenience frontend to jpegtran, allowing JPEG images to be rotated, mirrored, or transposed in several ways.  These opera-
       tions are conducted losslessly (i.e., no image recompression) and keep all EXIF metadata intact.

OPTIONS

       -f, -flip, --flip {horizontal | vertical}
	      horizontal: Mirror image horizontally (left-right).
	      vertical	: Mirror image vertically (top-bottom).

       -r, -rotate, --rotate {90 | 180 | 270}
	      90 : Rotate image 90 degrees clockwise.
	      180: Rotate image 180 degrees.
	      270: Rotate image 270 degrees clockwise (or 90 ccw).

       -tp, -transpose, --transpose
	      Transpose image (across UL-to-LR axis).

       -tv, -transverse, --transverse]
	      Transverse transpose (across UR-to-LL axis).

imagerotate - Rotate an image with a given angle

SYNOPSIS

       resource imagerotate (resource  $image, float  $angle, int  $bgd_color, [int  $ignore_transparent])

DESCRIPTION

	Rotates the $image image using the given $angle in degrees.

	The center of rotation is the center of the image, and the rotated image may have different dimensions than the original image.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $angle
		- Rotation angle, in degrees. The rotation angle is interpreted as the number of degrees to rotate the image anticlockwise.

	      o $bgd_color
		- Specifies the color of the uncovered zone after the rotation

	      o $ignore_transparent
		- If set and non-zero, transparent colors are ignored (otherwise kept).

RETURN VALUES

	Returns an image resource for the rotated image, or FALSE on failure.

EXAMPLES

       Example #1

	      Rotate an image 180 degrees

	       This example rotates an image 180 degrees - upside down.

	      <?php
	      // 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);

	      // Free the memory
	      imagedestroy($source);
	      imagedestroy($rotate);
	      ?>

	      The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : Rotate an image 180 degrees

NOTES

       Note

	      This function is affected by the interpolation method set by imagesetinterpolation(3).
