这篇文章主要介绍了PHP基于php_imagick_st-Q8.dll实现JPG合成GIF图片的方法,需要的朋友可以参考下
一、概述:
本文详解了PHP基于php_imagick_st-Q8.dll实现JPG合成GIF图片的方法。
首先要实现PHP使用php_imagick_st-Q8.dll类库,把JPG图片连接生成GIF动画图片,需要事先下载好php_imagick_st-Q8.dll动态链接库文件,并配置php.ini文件,启用php_imagick_st-Q8.dll。
二、配置方法如下:
1、将下载的php_imagick_st-Q8.dll文件放到PHP默认的扩展目录,也就是:php/ext/目录内;
2、打开php.ini,在extension区域新加入此行,注意前面不要有“;”,即:
extension=php_imagick_st-Q8.dll
3、重启apache或IIS。
三、PHP实现代码如下:
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 . '
';
echo "";
}
else
{
echo '已生成gif图片: ' . $images . '
';
}
//删除原来保存的图片
unlink($images);
}
?>
