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 "PHP基于php_imagick_st-Q8.dll实现JPG合成GIF图片的方法"; } else { echo '已生成gif图片: ' . $images . '
'; } //删除原来保存的图片 unlink($images); } ?>
