Question

我刚刚找到了用于制作动画gif的php库我想我已经编辑了示例代码，但我得到了错误GIFEncoder V2.05: 0 Source is not a GIF image!。

任何使用过这个php课程的人都可以帮助我吗？下面是我使用的代码，我已经注释了＆＃34;示例＆＃34;代码。

<?php

include "GIFEncoder.class.php";
/*
Build a frames array from sources...

if ( $dh = opendir ( "frames/" ) ) {
while ( false !== ( $dat = readdir ( $dh ) ) ) {
    if ( $dat != "." && $dat != ".." ) {
        $frames [ ] = "frames/$dat";
        $framed [ ] = 5;
    }
}
closedir ( $dh );
} 
*/
$frames = array("http://www.hoppvader.nu/weatherpics/Windsock1/windsock-10.gif","http://www.hoppvader.nu/weatherpics/Windsock1/windsock-20.gif","http://www.hoppvader.nu/weatherpics/Windsock1/windsock-30.gif");
$framed = array(40, 80, 40);
/*
    GIFEncoder constructor:

    image_stream = new GIFEncoder   (

                        int                 'Source type'
                    );
*/
$gif = new GIFEncoder   (
                        $frames,
                        $framed,
                        0,
                        2,

echo    $gif->GetAnimation ( );

你应该使用Gifcreator：

https://github.com/Sybio/GifCreator

<?php
   include "GifCreator.php";

   // create an array with images
   $frames =  array(imagecreatefromjpeg("pic1.jpg"),
                    imagecreatefromjpeg("pic2.jpg"),
                    imagecreatefromjpeg("pic3.jpg"));

   // the time each image should be visible in ms
   $time = array(20,20,20); 

   // create the gif-image
   $gc = new \GifCreator\GifCreator();
   $gc->create($frames, $durations, 0);

   $gifBinary = $gc->getGif();

   header('Content-type: image/gif');
   header('Content-Disposition: filename="GIF-image"');

   //echo the GIF-image
   echo $gifBinary;

?>

我没有使用GIFencoder，但我使用过GIFcreator，这就是我建议的原因。

使用Gifencoderclass.php动画gif，源不是GIF
