Приклад #1 imagegrabwindow() example
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");
imagedestroy($im);
?>Capture a window (IE for example) but with its content
<?php
$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
$browser->Visible = true;
$browser->Navigate("http://www.libgd.org");
/* Still working? */
while ($browser->Busy) {
com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
imagepng($im, "iesnap.png");
imagedestroy($im);
?>If you just want to take a screenshot of a website WITHOUT the ugly IE window around it, the easiest way is setting the "Fullscreen" property to TRUE.
$browser->Fullscreen = true;
This is basically the same as pressing F11 once the browser is open, so you just get the actual website.
