PHP implements the method of synthesizing GIF images from JPG based on php_imagick_st-Q8.dll, _PHP tutorial

PHP implements the method of synthesizing JPG into GIF images based on php_imagick_st-Q8.dll,

1. Overview:

This article explains in detail how PHP implements JPG synthesis of GIF images based on php_imagick_st-Q8.dll.
First, you need to implement PHP using the php_imagick_st-Q8.dll class library to connect JPG images to generate GIF animated images. You need to download the php_imagick_st-Q8.dll dynamic link library file in advance, configure the php.ini file, and enable php_imagick_st-Q8. .dll.

2. The configuration method is as follows:

1.

Put the downloaded php_imagick_st-Q8.dll file into the PHP default extension directory, which is: php/ext/ directory ; 2. Open php.ini and add this line in the extension area. Be careful not to have ";" in front of it, that is:
extension=php_imagick_st-Q8.dll
3.
Restart apache or IIS.

3. The PHP implementation code is as follows:

<&#63;php
//定义JPG的图片序列
$filelist = array(
  '1.jpg',
  '2.jpg',
  '3.jpg',
  '4.jpg'
);
$type = 'gif';
$num = 200;
$qian = 'new_';
$path = './gif/';
$is = 1;
//生成gif图片的函数
get_img($filelist, $type, $num, $qian, $path, $is);
/*
 * get_img 图片合并,生成gif动态
 * $filelist 要合并的图片数组
 * $type 生成的类型
 * $num 生成的帧数
 * $qian 新文件名前缀
 * $path 保持路径
 * $is 是否预览
 */
function get_img($filelist, $type, $num, $qian, $path, $is)
{
 //初始化类
 $animation = new Imagick();
 //设置生成的格式
 $animation->setFormat($type);
 foreach ( $filelist as $file ){
 $image = new Imagick();
 $image->readImage( $file );  //合并图片
 $animation->addImage( $image ); //加入到对象
 $animation->setImageDelay($num); //设定图片帧数
 unset( $image );    //清除内存里的图像，释放内存
 }
 //以下两行是调试时用的，测试是否生成了gif图片
 //header( "Content-Type: image/gif" );
 //echo( $animation->getImagesBlob() );
 //生成的GIF文件名组合
 $images = $qian . time(). '.' . $type;
 //生成GIF图片
 $animation->writeImages( $images,true );
 //保存GIF到指定文件夹
 copy($images, $path . $images);
 //是否预览
 if($is)
 {
 echo '已生成gif图片: ' . $images . '<br />';
 echo "<img  src='" . $path . $images . "' / alt="PHP implements the method of synthesizing GIF images from JPG based on php_imagick_st-Q8.dll, _PHP tutorial" >";
 }
 else
 {
 echo '已生成gif图片: ' . $images . '<br />';
 }
 //删除原来保存的图片
 unlink($images);
}
