ie6 - gd和php图像输出 [英] ie6 - gd and php image outputting

问题描述

我正在尝试使用灰度滤镜显示图像。这是我的代码：

i'm trying to show image with grayscale-filter. Here is my code:

$images = glob('gallery/*small*');
shuffle($images);
array_splice($images, 3);

$imgHandles = array();
$imgBuffered = array();
for( $i = 0; $i < 3; $i++)
{  
   $imgHandles[$i] = imagecreatefromstring( file_get_contents($images[$i]) ); 
   imagefilter( $imgHandles[$i], IMG_FILTER_GRAYSCALE ); 

   ob_start();
   imagepng( $imgHandles[$i] ); 
   $imgBuffered[$i] = ob_get_contents();
   ob_end_clean();
   imagedestroy( $imgHandles[$i] ); 
} 

输出：

for( $i = 0; $i < 3; $i++ )
{  
   echo "<a href=\"gallery.php\">
   <img class=\"photo\" src='data:image/png;base64,".base64_encode( $imgBuffered[$i] )."' /></a>";                                                                                    
}

在歌剧，ff，chrome，safari中一切都很好，但ie6没有' t显示图像。为什么？

我在页面上创建了代码： http://dean.edwards.name/weblog/2005/06/base64-ie/
我看到图片，但在几秒钟内他们隐藏了......我真的不知道为什么。你可以帮我解决这个问题吗？

In opera, ff, chrome, safari everything is fine, but ie6 doesn't show images. Why?

I made code like at page: http://dean.edwards.name/weblog/2005/06/base64-ie/ I see pictures, but in some seconds they hide... I really don't know why. Can you help me with this stuff?

推荐答案

数据URI方案不支持 =nofollow noreferrer>。您需要将图像保存到某处并以 img src 的形式提供保存图像的URL，或者您需要通过单独的脚本动态生成它并执行类似 img src =path / to / image_generator.php。

The data URI scheme isn't supported in IE6 (nor IE7, apparently). You'll need to save the image somewhere and provide the URL to the saved image as the img src, or you'll need to generate it on the fly via a separate script and do something like img src="path/to/image_generator.php".
