1，首先你必须生成二维码具体代码如下：
class QRCode{
public $w;
public $h;
public $s;
function __construct($w1,$h1,$s1){
$this->w = $w1;
$this->h = $h1;
$this->s = $s1;
$this->outimgase();
}
function qrcode(){
$post_data = array();
$post_data['cht'] = 'qr';
$post_data['chs'] = $this->w."x".$this->h;
$post_data['chl'] = $this->s;
$post_data['choe'] = "UTF-8";
$url = "http://chart.apis.google.com/chart";
$data_Array = array();
foreach($post_data as $key => $value)
{
$data_Array[] = $key.'='.$value;
}
$data = implode("&",$data_Array);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
function outimgase(){
echo $this->qrcode();
}
}
header("Content-type:image/png");
$t = new QRCode(300,300,"tianxin");
2，然后通过一个php文件将二维码和你的目的图片画在一起代码如下：
$surl = $_POST["url"];
function GrabImage($url,$filename="") {
if($url==""):return false;endif;
if($filename=="") {
$ext=strrchr($url,".");
if($ext!=".gif" && $ext!=".jpg"):return false;endif;
$filename=date("dMYHis").$ext;
}
ob_start();
readfile($url);
$img = ob_get_contents();
ob_end_clean();
$size = strlen($img);
$fp2=@fopen($filename, "a");
fwrite($fp2,$img);
fclose($fp2);
返回$文件名；
}
$source = GrabImage("http://localhost/QRCode/QRCode.php","Myqrcode.png");
$water =GrabImage($surl,"t.png");
函数 getImageInfo($img){
$imageInfo = getimagesize($img);
if ($imageInfo !== false) {
$imageType = strtolower(substr(image_type_to_extension($imageInfo[2]), 1));
$imageSize = 文件大小($img);
$info = array(
"宽度" => $imageInfo[0],
"高度" => $imageInfo[1],
"类型" => $imageType,
"大小" => $imageSize,
"mime" => $imageInfo['mime']
);
返回$信息；
} else {
返回 false;
}
}
functionthumb($image, $thumbname, $type='', $maxWidth=200, $maxHeight=50, $interlace=true) {
//获取原图信息
$info = getImageInfo($image);
if ($info !== false) {
$srcWidth = $info['width'];
$srcHeight = $info['height'];
$type = 空($type) ? $info['type'] : $type;
$type = strtolower($type);
$交错 = $交错？ 1：0；
未设置($info);
$scale = min($maxWidth / $srcWidth, $maxHeight / $srcHeight); // 计算缩放比例
if ($scale >= 1) {
//超过原图大小不再缩放略
$width = $srcWidth;
$height = $srcHeight;
} else {
//最小尺寸
$width = (int) ($srcWidth * $scale);
$height = (int) ($srcHeight * $scale);
}
// 加载原图
$createFun = 'ImageCreateFrom' . ($type == 'jpg' ? 'jpeg' : $type);
$srcImg = $createFun($image);
//创建梦想
if ($type != 'gif' && function_exists('imagecreatetruecolor'))
$thumbImg = imagecreatetruecolor($width, $height);
其他
$thumbImg = imagecreate($width, $height);
// 复制图片
if (function_exists("ImageCopyResampled"))
imagecopyresampled($thumbImg, $srcImg, 0, 0, 0, 0, $width, $height, $srcWidth, $srcHeight) ;
else
imagecopyresized($thumbImg, $srcImg, 0, 0, 0, 0, $width, $height, $srcWidth, $srcHeight);
if ('gif' == $type || 'png' == $type) {
//imagealphablending($thumbImg, false);//取消默认的混色模式
//imagesavealpha( $thumbImg,true);//设置保存完整的alpha通道信息
$background_color = imagecolorallocate($thumbImg, 0, 255, 0); // 指派一个绿色
imagecolortransparent($thumbImg, $background_color); // 设置为透明颜色，若注释掉该行则输出绿色的图
}
//对jpeg图形设置隔行扫描
if ('jpg' == $type || 'jpeg' = = $type)
imageinterlace($thumbImg, $interlace);
//生成图片
$imageFun = 'image' . ($type == 'jpg' ? 'jpeg' : $type);
$imageFun($thumbImg, $thumbname);
imagedestroy($thumbImg);
imagedestroy($srcImg);
返回$thumbname;
}
返回 false；
}
功能水($source, $thumb, $savename="", $alpha=100){
//检查文件是否存在
if (!file_exists($source) || !file_exists($thumb))
返回 false;
//图片信息
$sInfo = getImageInfo($source);
$水 = 拇指($thumb,"wy.jpg","jpg",$sInfo["width"]/4,$sInfo["height"]/4);
$wInfo = getImageInfo($water);
//如果图片小于水印图片，不生成图片
if ($sInfo["width"] < $wInfo["width"] || $sInfo['height'] < $wInfo['高度'])
返回 false;
//创建图像
$sCreateFun = "imagecreatefrom" . $sInfo['类型'];
$sImage = $sCreateFun($source);
$wCreateFun = "imagecreatefrom" 。 $wInfo['类型'];
$wImage = $wCreateFun($water);
//设置图像的混色模式
imagealphablending($wImage, true);
//图像位置,默认为右下角右对齐
// $posY = $sInfo["height"] - $wInfo["height"];
// $posX = $sInfo["width"] - $wInfo["width"];
$posY = ($sInfo["height"] - $wInfo["height"])/2;
$posX = ($sInfo["width"] - $wInfo["width"])/2;
//生成混合图像
imagecopymerge($sImage, $wImage, $posX, $posY, 0, 0, $wInfo['width'], $wInfo['height'], $alpha);
//输出图像
$ImageFun = 'Image' . $sInfo['类型'];
//如果没有给出保存文件名，默认为原图像名
if (!$savename) {
$savename = $source;
@unlink($source);
}
//保存图片
$ImageFun($sImage, $savename);
imagedestroy($sImage);
}
水（$源，$水）；
在上面的代码中用3个函数 GrabImage（）函数是将生成二维码的文件转化成图片 接下来的函数就是处理图片的缩放 将目的图片添加到二位上。
3，在来一个入口文件index.html 代码如下：
<br>中间可以自己定义图片的二维码生成器 <br>
