Imagick::shearImage — Creating a parallelogram
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.
backgroundThe background color
x_shearThe number of degrees to shear on the x axis
y_shearThe number of degrees to shear on the y axis
成功时返回 true。
| 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 #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();
}
