Imagick::shearImage

    (PECL imagick 2, PECL imagick 3)

    Imagick::shearImage — Creating a parallelogram

    说明

    publicImagick::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
    PECL imagick 2.1.0 Now allows a string representing the color as the first parameter. Previous versions allow only an ImagickPixel object.

    示例

    示例 #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();
    }

    ?>
