PHP抓屏函数实现屏幕快照代码分享

复制代码 代码如下:

* 屏幕快照
$im = imagegrabscreen();
imagepng($im, "myscreenshot.png");

* 抓取一个窗口(IE为例)

$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
$browser->Visible = true;
$im = imagegrabwindow($handle);
$browser->Quit();
imagepng($im, "iesnap.png");
$im = imagegrabscreen();

// 抓取IE窗口及窗口内容(IE为例)

$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
$browser->Visible = true;
$browser->Navigate("http://www.jb51.net");

/* Still working? */
while ($browser->Busy) {
com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
imagepng($im, "iesnap.png");

//IE全屏模式

$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;

$browser->Visible = true;
$browser->FullScreen = true;
$browser->Navigate("http://www.jb51.nett");

/* Is it completely loaded? (be aware of frames!)*/
while ($browser->Busy) {
com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
imagepng($im, "iesnap.png");
?>

需要说明几点
1.这二种方法只能工作在windows下面,
2. 黑屏解决办法--->>web 服务器(iis或apache)做为windows服务时，必须打开"允许与桌面交互"的选项.(点击服务属性->登录->勾选"允许与桌面 交互".(一定要记得重起apache或其他的服务器才会有用,我已经成功，无庸质疑)
3.需要gb库版本为2.0.34(php5.2.2默认自带)
