PHP应用：利用php_imagick实现复古效果的方法

<?php
header('Content-type: image/jpeg');
$image = new Imagick('image.jpg');
// If 0 is provided as a width or height parameter,// aspect ratio is maintained
$image->thumbnailImage(100, 0);
echo $image;
?>

<?php
$images = new Imagick(glob('images/*.JPG'));
foreach($images as $image) {
// Providing 0 forces thumbnailImage to maintain aspect ratio
$image->thumbnailImage(1024,0);
}
$images->writeImages();
?>

<?php
/* Create a new imagick object and read in GIF */
$im = new Imagick("example.gif");
/* Resize all frames */
foreach ($im as $frame) {
/* 50x50 frames */
$frame->thumbnailImage(50, 50);
/* Set the virtual canvas to correct size */
$frame->setImagePage(50, 50, 0, 0);
}/* Notice writeImages instead of writeImage */
$im->writeImages("example_small.gif", true);
?>

//打开图片
$im = new Imagick('./hebe.jpg');
//新建图层,使用颜色`#C0FFFF`填充后,不透明度设为`44%`
$layer = new Imagick();
$layer->newImage($im->getImageWidth(), $im->getImageHeight(), '#C0FFFF');
$layer->setImageOpacity (0.44);
//叠加到原图上,图层混合模式为`柔光`
$im->compositeImage($layer, Imagick::COMPOSITE_SOFTLIGHT, 0, 0);
//新建图层,使用颜色`#000699`填充后,不透明设置为`48%`
$layer = new Imagick();
$layer->newImage($im->getImageWidth(), $im->getImageHeight(), '#000699');
$layer->setImageOpacity (0.48);
//叠加到原图上,图层混合模式为`排除` 
$im->compositeImage($layer, Imagick::COMPOSITE_EXCLUSION, 0, 0);
//完成!
$im->writeImage('./vintage.jpg');
