讲述了 maptiler的历史,现在开始坑钱了。

还 fork 了一个 php的 php-maptiler

下面是拼图程序:

<?php
$imgs = array();
$imgs[0] = 'imgs/1.jpg';
$imgs[1] = 'imgs/2.jpg';
$imgs[2] = 'imgs/3.jpg';
$imgs[3] = 'imgs/4.jpg';
$target = 'emp.jpg';//背景图片

$target_img = Imagecreatefromjpeg($target);

$source= array();

foreach ($imgs as $k=>$v){

$source[$k]['source'] = Imagecreatefromjpeg($v);

$source[$k]['size'] = getimagesize($v);

}

//imagecopy ($target_img,$source[0]['source'],2,2,0,0,$source[0]['size'][0],$source[0]['size'][1]);
//imagecopy ($target_img,$source[1]['source'],250,2,0,0,$source[1]['size'][0],$source[1]['size'][1]);
$num1=0;
$num=1;
$tmp=2;
$tmpy=2;//图片之间的间距
for ($i=0; $i<4; $i++){
imagecopy($target_img,$source[$i]['source'],$tmp,$tmpy,0,0,$source[$i]['size'][0],$source[$i]['size'][1]);

$tmp = $tmp+$source[$i]['size'][0];
$tmp = $tmp+5;
if($i==$num){
$tmpy = $tmpy+$source[$i]['size'][1];
$tmpy = $tmpy+5;
$tmp=2;
$num=$num+3;
}
}
Imagejpeg($target_img,'pin.jpg');

?>
<img src="pin.jpg">
