类的代码:

本文实例讲述了php_imagick实现图片剪切、旋转、锐化、减色或增加特效的方法。分享给大家供大家参考。具体分析如下:

复制代码 代码如下:

一个可以供PHP调用ImageMagick功能的PHP扩展。使用这个扩展可以使PHP具备和ImageMagick相同的功能。

ImageMagick是一套功能强大、稳定而且免费的工具集和开发包,可以用来读、写和处理超过185种基本格式的图片文件,包括流行的TIFF, JPEG, GIF, PNG, PDF以及PhotoCD等格式。利用ImageMagick,你可以根据web应用程序的需要动态生成图片, 还可以对一个(或一组)图片进行改变大小、旋转、锐化、减色或增加特效等操作,并将操作的结果以相同格式或其它格式保存。

将上面的代码保存为 class_qrcode.php
调用方法:

效果演示:

说明:

因为这个类的代码太长了,每次发布的时候cnblog都报错,所以只好使用代码加密的方式,已达到缩短代码的目的

  • PHP开发框架Laravel数据库操作方法总结
  • Laravel使用PHPQRCODE实现生成带有LOGO的二维码图片功能示例

1、下载 ImageMagick并安装

2、下载php_imagick.dll

如果你用的是线程安全的php,请下载

windows-builds/php53/imagick-2.3.0-dev/vc9_zts/php_imagick.dll

3、设置

在php.ini中添加

extension=php_imagick.dll ,重启web server

二、linux下安装Imagick扩展:

1.yum安装ImageMagick

yum install ImageMagick ImageMagick-devel

2.测试是否安装成功

convert -version

3.安装imagick扩展
 
01.wget xzvf imagick-3.1.0RC2.tgz03.cd imagick-3.1.0RC204.phpize05../configure06.make07.make install

4.编辑php.ini文件,在文件末尾添加如下代码

extension=imagick.so

  1. 重新启动apache服务器

service httpd restart

三、案例

  1. 边框处理

复制代码 代码如下:

header('Content-type: image/jpeg'); 
$image = new Imagick('test.jpg'); 
$color=new ImagickPixel(); 
$color->setColor("rgb(220,220,220)"); 
$image->borderImage($color,5,4); 
$image->blurImage(5,5,imagick::CHANNEL_GREEN); 
echo $image;

我们先来看个简单的实例

php_imagick程序示例

1.创建一个缩略图并显示出来

复制代码 代码如下:

<?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; 
?>

2.创建一个目录下的缩略图,并保存

复制代码 代码如下:

<?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(); 
?>

3.缩略GIF动画图片

复制代码 代码如下:

<?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); 
?>

现在我们进入正题吧,

示例:

裁切/生成缩略图/添加水印, 自动检测和处理 GIF

调用方式:

复制代码 代码如下:

include 'imagick.class.php'; 
$image = new lib_image_imagick(); 
$image->open('a.gif'); 
$image->resize_to(100, 100, 'scale_fill'); 
$image->add_text('1024i.com', 10, 20); 
$image->add_watermark('1024i.gif', 10, 50); 
$image->save_to('x.gif');
imagick.class.php

                $canvas->setImageDelay( $img->getImageDelay() ); 
                $canvas->setImagePage($width, $height, 0, 0); 
            }
