以下代码是imagick Imagick::annotateImage()
函数的一个非常基本的示例。如何在保留背景图像的同时屏蔽文本的上半部分?
<?php
/* Create some objects */
$image = new Imagick('bg.jpg');
$draw = new ImagickDraw();
$pixel = new ImagickPixel( 'transparent' );
/* New image */
$image->newImage(800, 75, $pixel);
/* Black text */
$draw->setFillColor('black');
/* Font properties */
$draw->setFont('Bookman-DemiItalic');
$draw->setFontSize( 30 );
/* Create text */
$image->annotateImage($draw, 10, 45, 0, 'The quick brown fox jumps over the lazy dog');
/* Give image a format */
$image->setImageFormat('png');
/* Output the image with headers */
header('Content-type: image/png');
echo $image;
?>
