生成海报网上有很多,其主要方法都一致,这个存储只是我不想再去百度了噻

核心方法如下:各位看下就可

/**
 * 生成宣传海报
 * @param array  参数,包括图片和文字
 * @param string  $filename 生成海报文件名,不传此参数则不生成文件,直接输出图片
 * @return [type] [description]
 */
function createPoster($config=array(),$filename="")
{
    #如果要看报什么错,可以先注释调这个header
    if(empty($filename)) header("content-type: image/png");
    $imageDefault = [
        \'left\'=>0,
        \'top\'=>0,
        \'right\'=>0,
        \'bottom\'=>0,
        \'width\'=>100,
        \'height\'=>100,
        \'opacity\'=>100
    ];
    $textDefault = [
        \'text\'=>\'\',
        \'left\'=>0,
        \'top\'=>0,
        \'fontSize\'=>32,       //字号
        \'fontColor\'=>\'255,255,255\', //字体颜色
        \'angle\'=>0,
    ];

    $background = $config[\'background\'];//海报最底层得背景

    #背景方法
    $backgroundInfo = getimagesize($background);
    $backgroundFun = \'imagecreatefrom\'.image_type_to_extension($backgroundInfo[2], false);
    $background = $backgroundFun($background);
    $backgroundWidth = imagesx($background);  //背景宽度
    $backgroundHeight = imagesy($background);  //背景高度
    $imageRes = imageCreatetruecolor($backgroundWidth,$backgroundHeight);
    $color = imagecolorallocate($imageRes, 0, 0, 0);
    imagefill($imageRes, 0, 0, $color);

    // imageColorTransparent($imageRes, $color);  //颜色透明
    imagecopyresampled($imageRes,$background,0,0,0,0,imagesx($background),imagesy($background),imagesx($background),imagesy($background));

    #处理图片
    if(!empty($config[\'image\'])){
        foreach ($config[\'image\'] as $key => $val) 
        {
            $val = array_merge($imageDefault,$val);
            $info = getimagesize($val[\'url\']);
            $function = \'imagecreatefrom\'.image_type_to_extension($info[2], false);

            #如果传的是字符串图像流
            if($val[\'stream\'])
            {   
                $info = getimagesizefromstring($val[\'url\']);
                $function = \'imagecreatefromstring\';
            }
            $res = $function($val[\'url\']);
            $resWidth = $info[0];
            $resHeight = $info[1];

            #建立画板 ,缩放图片至指定尺寸
            $canvas=imagecreatetruecolor($val[\'width\'], $val[\'height\']);
            imagefill($canvas, 0, 0, $color);

            #关键函数,参数(目标资源,源,目标资源的开始坐标x,y, 源资源的开始坐标x,y,目标资源的宽高w,h,源资源的宽高w,h)
            imagecopyresampled($canvas, $res, 0, 0, 0, 0, $val[\'width\'], $val[\'height\'],$resWidth,$resHeight);
            $val[\'left\'] = $val[\'left\']<0?$backgroundWidth- abs($val[\'left\']) - $val[\'width\']:$val[\'left\'];
            $val[\'top\'] = $val[\'top\']<0?$backgroundHeight- abs($val[\'top\']) - $val[\'height\']:$val[\'top\'];
            #放置图像
            imagecopymerge($imageRes,$canvas, $val[\'left\'],$val[\'top\'],$val[\'right\'],$val[\'bottom\'],$val[\'width\'],$val[\'height\'],$val[\'opacity\']);//左,上,右,下,宽度,高度,透明度
        }
    }

    #处理文字
    if(!empty($config[\'text\']))
    {
        foreach ($config[\'text\'] as $key => $val) 
        {
            $val = array_merge($textDefault,$val);
            list($R,$G,$B) = explode(\',\', $val[\'fontColor\']);
            $fontColor = imagecolorallocate($imageRes, $R, $G, $B);
            $val[\'left\'] = $val[\'left\']<0?$backgroundWidth- abs($val[\'left\']):$val[\'left\'];
            $val[\'top\'] = $val[\'top\']<0?$backgroundHeight- abs($val[\'top\']):$val[\'top\'];
            imagettftext($imageRes,$val[\'fontSize\'],$val[\'angle\'],$val[\'left\'],$val[\'top\'],$fontColor,$val[\'fontPath\'],$val[\'text\']);
        }
    }
    
    #生成图片
    if(!empty($filename))
    {
        $res = imagejpeg ($imageRes,$filename,90); //保存到本地
        imagedestroy($imageRes);
        if(!$res) return false;
        return $filename;
    }else{
        imagejpeg ($imageRes);     //在浏览器上显示
        imagedestroy($imageRes);
    }
}

 

然后对应方法调用即可

本人使用方法,看下就行,比较辣鸡

#两张调用
function addTwoimage($reqrcode,$bjimg,$filename)
{
    $reqrcodes = ROOT_PATH . \'/public\'.$reqrcode; //背景图目录
    // $reqrcodes = ROOT_PATH . \'/public\'; //背景图目录
    $config = array(
            \'image\'=>array(
                array(
                    \'url\'=>$reqrcodes,      //二维码资源
                    \'stream\'=>0,
                    \'left\'=>177,
                    \'top\'=>470,
                    \'right\'=>0,

    return createPoster($config,$filename);
}

        ),
       \'image\'=>array(
            array(

    return  createPoster($config,$filename);
}
