PHP修改图片尺寸并输出(附API)

图片尺寸什么的一直很烦人,太大?太小?占带宽?七牛有一个缩略图的API,不过可惜的是那个缩略图API只能在七牛的文件使用,变大变小都不能随心所欲!那么怎么办呢?机智的小幻有想弄了一个修改尺寸的API,直接弄进去,然后输出好了的尺寸不就OK了?

当然,这个API各种伪静态未作,如果你有兴趣,可以修改下,用这个生成修改尺寸的图片,然后由七牛缓存,这一切都是可以实现的,不过对于我这样的渣渣来说,伪静态,不会啊!

php修改图片尺寸API源码:

<?php
// The file
if($_GET["url"]){
    $filename=$_GET["url"];
// Set a maximum height and width
if($_GET["w"]){
    $width=$_GET["w"];
}else{
$width="2156";
}
if($_GET["h"]){
    $width=$_GET["h"];
}else{
$height="2156";
}

// Content type
header('Content-Type: image/jpeg');

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, null, 100);
}else{
header('Content-Type: text/html; charset=utf-8');
echo'<meta http-equiv="refresh" content="3;url=http://tu.ihuan.me">';
echo"您输入的参数有误,请重新输入———小幻美图(tu.ihuan.me)";
}
?>

是按照比例进行修改的,欢迎各位大神挑刺!

下面弄个图像吧image.php(生成的300宽图像原图1366)

好了,当然我这里也有API的

网络图片尺寸修改API

图片尺寸修改API地址:http://tu.ihuan.me/api/image.php?url=http://xxx.xxx&w=xxx&h=xxx

其中url=后参数必须填写,其他可不填写,填写w或h其中一项则按照其中的参数成比例修改尺寸

  • url=其后接需要修改图片的网址以http或https开头
  • w=后接修改后图片宽度
  • h=后接修改后图片高度

示例:http://tu.ihuan.me/api/image.php?url=http://s.cn.bing.net/az /hprichbg/rb/PetrifiedForestNP_ZH-CN10820635777_1366x768.jpg&w=500

但是,我这里不能进行缓存,如果自己想要,可以把上面的文件弄下来,然后自己修改下,存到七牛里(真是太机智了!)

如果有写好了的伪静态规则,给我份吧!我是真的不会写,简单的还行,可是这个不简单。

好了,就这些了,欢迎大家食用,流量大的还是用自己的空间来执行吧,小站受不了!

最后打个AD:欢迎大家食用本站的随机图片等API,已经有100张图了,配合一下上面的API食用更美味!

    I needed to send you that little remark to say thanks a lot once again just for the spectacular opinions you have shown at this time. It has been simply particularly open-handed of you to convey unreservedly precisely what many people might have made available for an e-book to get some profit for their own end, notably since you might have done it if you ever considered necessary. These things additionally acted to be a easy way to know that many people have the same eagerness the same as my personal own to realize significantly more in respect of this matter. I know there are a lot more pleasant periods ahead for many who read your blog post.
