    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::borderImage()

    <?php
    function borderImage($imagePath, $color, $width, $height) {
        $imagick = new \Imagick(realpath($imagePath));
        $imagick->borderImage($color, $width, $height);
        header("Content-Type: image/jpg");
        echo $imagick->getImageBlob();
    }
    ?>
    
    To get an image with exact dimensions (i.e. add whitespace) use with borderImage: 
    $desired_width = 1000;
    $desired_height = 1000;
     $image->scaleImage($desired_width,$desired_height , true);
     $image->borderImage('white', ($image->getImageWidth() - $desired_width) / 2,($image->getImageHeight() - $desired_height ) / 2);
