Imagick::shearImage
(PECL imagick 2, PECL imagick 3)
Imagick::shearImage — Creating a parallelogram
Description
public Imagick::shearImage
( mixed $background
, float $x_shear
, float $y_shear
) : bool
Slides one edge of an image along the X or Y axis, creating a parallelogram. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis. The amount of the shear is controlled by a shear angle. For X direction shears, x_shear is measured relative to the Y axis, and similarly, for Y direction shears y_shear is measured relative to the X axis. Empty triangles left over from shearing the image are filled with the background color.
Parameters
background- The background color
x_shear- The number of degrees to shear on the x axis
y_shear- The number of degrees to shear on the y axis
Return Values
Returns TRUE on success.
Changelog
| Version | Description |
|---|---|
| PECL imagick 2.1.0 | Now allows a string representing the color as the first parameter.
Previous versions allow only an ImagickPixel object. |
Examples
Example #1 Imagick::shearImage()
<?phpfunction shearImage($imagePath, $color, $shearX, $shearY) { $imagick = new \Imagick(realpath($imagePath)); $imagick->shearimage($color, $shearX, $shearY); header("Content-Type: image/jpg"); echo $imagick->getImageBlob();}?>
