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);
