  • Imagick::shearImage()

    (PECL imagick 2.0.0)

    Creating a parallelogram

    说明

    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.

    参数

    $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

    返回值

    成功时返回TRUE

    更新日志

    版本说明
    2.1.0 Now allows a string representing the color as the first parameter. Previous versions allow only an ImagickPixel object.

    范例

    Example #1 Imagick::shearImage()

    <?php
    function shearImage($imagePath, $color, $shearX, $shearY) {
        $imagick = new \Imagick(realpath($imagePath));
        $imagick->shearimage($color, $shearX, $shearY);
        header("Content-Type: image/jpg");
        echo $imagick->getImageBlob();
    }
    ?>
    
    Eg:
    <?php
    $image = new Imagick('pic.png');
    $image ->shearImage('grey', 10 , 5);
    $image ->writeImage('final.png');
    ?>
