内容图文

大家估计都用手机玩过 化妆整人的程序

也就是对照片加工处理 添加饰物 然后生成一张图片 可以搞笑娱乐大家

本文主要采用的技术有

1.jquery的拖拽 drag& drop技术

2.PHP转换Json data

3.CSS3 +ＨＴＭＬ５

首先我们建立一个大体的框架

?采用的ｃｓｓ　

#content{
    position:relative;
    width:1105px;
    height:500px;
    margin:40px auto 0px auto;
    background-color:#F9F9F9;
    -moz-border-radius:6px;
    -webkit-border-radius:6px;
    border-radius:6px;
    -moz-box-shadow:0px 0px 8px #ccc;
    -webkit-box-shadow:0px 0px 8px #ccc;
    box-shadow:0px 0px 8px #ccc;
}
.background{
    position:absolute;
    width:640px;
    height:480px;
    top:10px;
    left:215px;
    -moz-box-shadow:0px 0px 3px #bbb;
    -webkit-box-shadow:0px 0px 3px #bbb;
    box-shadow:0px 0px 3px #bbb;
}

?然后是拖拽的元素和图片的　ｃｓｓ样式

#objects{
    width:210px;
    height:486px;
    top:10px;
    left:10px;
    position:absolute;
}
.obj_item{
    width:70px;
    height:70px;
    float:left;
}
#tools{
    width:230px;
    top:8px;
    right:10px;
    position:absolute;
    height:420px;
    overflow-y:scroll;
    overflow-x:hidden;
}
.item{
    border:3px solid #fff;
    background-color:#ddd;
    height:60px;
    position:relative;
    margin:2px 5px 2px 2px;
    -moz-border-radius:3px;
    -webkit-border-radius:3px;
    border-radius:3px;
    -moz-box-shadow:0px 0px 2px #999;
    -webkit-box-shadow:0px 0px 2px #999;
    box-shadow:0px 0px 2px #999;
}
.thumb{
    width:50px;
    height:50px;
    margin:5px;
    float:left;
}
.slider{
    float: left;
    width: 115px;
    margin: 30px 0px 0px 5px;
    background-color:#fff;
    height:10px;
    position:relative;
}
.slider span{
    font-size:10px;
    font-weight:normal;
    margin-top:-25px;
    float:left;
}
.slider span.degrees{
    position:absolute;
    right:-22px;
    top:20px;
    width:20px;
    height:20px;
}
.slider .ui-slider-handle {
    width:10px;
    height:20px;
    outline:none;
}
a.remove{
    width:16px;
    height:16px;
    position:absolute;
    top:0px;
    right:0px;
    background:transparent url(../images/cancel.png) no-repeat top left;
    opacity:0.5;
    cursor:pointer;
}
a.remove:hover{
    opacity:1.0;
}

饰品元素　被存储在ｊｓｏｎ　ｄａｔａ中

var data = {
    "images": [
        {"id" : "obj_0" ,"src" : "", "width" : "640", "height" : "480"}
    ]
};

?另外元素可以放大缩小　并且可以拖拽

$('#objects img').resizable({
    handles : 'se',
    stop    : resizestop
}).parent('.ui-wrapper').draggable({
    revert  : 'invalid'
});

$('#background').droppable({
    accept  : '#objects div', /* accept only draggables from #objects */
    drop    : function(event, ui) {
        var $this       = $(this);
        ++count_dropped_hits;
        var draggable_elem = ui.draggable;
        draggable_elem.css('z-index',count_dropped_hits);
        /* object was dropped : register it */
        var objsrc      = draggable_elem.find('.ui-widget-content').attr('src');
        var objwidth    = parseFloat(draggable_elem.css('width'),10);
        var objheight   = parseFloat(draggable_elem.css('height'),10);
 
        /* for top and left we decrease the top and left of the droppable element */
        var objtop      = ui.offset.top - $this.offset().top;
        var objleft     = ui.offset.left - $this.offset().left;
 
        var objid       = draggable_elem.find('.ui-widget-content').attr('id');
        var index       = exist_object(objid);
        if(index!=-1) { //if exists update top and left
            data.images[index].top  = objtop;
            data.images[index].left = objleft;
        }
        else{
            /* register new one */
            var newObject = {
                'id'        : objid,
                'src'       : objsrc,
                'width'     : objwidth,
                'height'    : objheight,
                'top'       : objtop,
                'left'      : objleft,
                'rotation'  : '0'
            };
            data.images.push(newObject);
            /* add object to sidebar*/
 
            $('',{
                className   :   'item'
            }).append(
                $('',{
                    className   :   'thumb',
                    html        :   ''
                })
            ).append(
                $('',{
                    className   :   'slider',
                    html        :   'Rotate0'
                })
            ).append(
                $('',{
                    className   :   'remove'
                })
            ).append(
                $('',{
                    type        :   'hidden',
                    value       :   objid       // keeps track of which object is associated
                })
            ).appendTo($('#tools'));
            $('.slider').slider({
                orientation : 'horizontal',
                max         : 180,
                min         : -180,
                value       : 0,
                slide       : function(event, ui) {
                    var $this = $(this);
                    /* Change the rotation and register that value in data object when it stops */
                    draggable_elem.css({
                        '-moz-transform':'rotate('+ui.value+'deg)',
                        '-webkit-transform':'rotate('+ui.value+'deg)'
                    });
                    $('.degrees',$this).html(ui.value);
                },
                stop        : function(event, ui) {
                    newObject.rotation = ui.value;
                }
            });
        }
    }
});

?下面是整体的ｐｈｐ文件

$res = JSON_decode(stripslashes($_POST['JSONdata']), true);
/* get data */
$count_images   = count($res['images']);
/* the background image is the first one */
$background     = $res['images'][0]['src'];
$photo1         = imagecreatefromjpeg($background);
$foto1W         = imagesx($photo1);
$foto1H         = imagesy($photo1);
$photoFrameW    = $res['images'][0]['width'];
$photoFrameH    = $res['images'][0]['height'];
$photoFrame     = imagecreatetruecolor($photoFrameW,$photoFrameH);
imagecopyresampled($photoFrame, $photo1, 0, 0, 0, 0, $photoFrameW, $photoFrameH, $foto1W, $foto1H);
 
/* the other images */
for($i = 1; $i < $count_images; ++$i){
    $insert         = $res['images'][$i]['src'];
    $photoFrame2Rotation = (180-$res['images'][$i]['rotation']) + 180;
 
    $photo2         = imagecreatefrompng($insert);
 
    $foto2W         = imagesx($photo2);
    $foto2H         = imagesy($photo2);
    $photoFrame2W   = $res['images'][$i]['width'];
    $photoFrame2H   = $res['images'][$i]['height'];
 
    $photoFrame2TOP = $res['images'][$i]['top'];
    $photoFrame2LEFT= $res['images'][$i]['left'];
 
    $photoFrame2    = imagecreatetruecolor($photoFrame2W,$photoFrame2H);
    $trans_colour   = imagecolorallocatealpha($photoFrame2, 0, 0, 0, 127);
    imagefill($photoFrame2, 0, 0, $trans_colour);
 
    imagecopyresampled($photoFrame2, $photo2, 0, 0, 0, 0, $photoFrame2W, $photoFrame2H, $foto2W, $foto2H);
 
    $photoFrame2    = imagerotate($photoFrame2,$photoFrame2Rotation, -1,0);
    /*after rotating calculate the difference of new height/width with the one before*/
    $extraTop       =(imagesy($photoFrame2)-$photoFrame2H)/2;
    $extraLeft      =(imagesx($photoFrame2)-$photoFrame2W)/2;
 
    imagecopy($photoFrame, $photoFrame2,$photoFrame2LEFT-$extraLeft, $photoFrame2TOP-$extraTop, 0, 0, imagesx($photoFrame2), imagesy($photoFrame2));
}
// Set the content type header - in this case image/jpeg
header('Content-type: image/jpeg');
imagejpeg($photoFrame, $targetfile);
imagedestroy($photoFrame);
