php實現截屏功能代碼

PHP使用GD庫實現截屏

PHP5.2.2以上版本的GD庫實現了兩個截屏函數 imagegrabscreen 和 imagegrabwindow
分別用於截取整個螢幕和截取某個視窗（同ALT+PrintScreen）的螢幕。

1. 截取整個螢幕 Screenshot

<?php
$im = imagegrabscreen();
imagepng($im, "myscreenshot.png");
?>

2. 截取一個視窗 Capture a window (IE for example)

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

3. 截取IE內容 Capture a window (IE for example) but with its content!

<?php
$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
$browser->Visible = true;
$browser->Navigate("http://www.21andy.com/blog/");
 
/* Still working? */
while ($browser->Busy) {
    com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
imagepng($im, "iesnap.png");
?>

4. 截取IE的全螢幕模式 IE in fullscreen mode

<?php
$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
 
$browser->Visible = true;
$browser->FullScreen = true;
$browser->Navigate("http://www.111cn.net");
 
/* 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");
?>
