Hello,
I want to capture a widget bitmap and save it to disk, I can do it
without any problem if the widget is shown on screen, but I would like
to do it without being shown, so I can build it on the background.
This code do the job, but on Vista, not in XP, that is, it creates a
window off screen and captures the bitmap, but the same code on XP it
creates a black bitmap:
<?php
if (!class_exists('gtk')) {
die("Please load the php-gtk2 module in your php.ini\r\n");
}
$btnLogin = new GtkCalendar();
$wnd = new GtkWindow();
$wnd->set_decorated(false);
$wnd->set_skip_taskbar_hint(false);
$wnd->move(-1000,-1000);
$wnd->add($btnLogin);
$wnd->show_all();
savewidgetbitmap($btnLogin, 't.bmp');
function savewidgetbitmap($widget, $filename)
{
$widget->show();
while (Gtk::events_pending())
{
Gtk::main_iteration();
}
$window= $widget->window;
list($width, $height)=$window->get_size();
$pixbuf = new GdkPixbuf(Gdk::COLORSPACE_RGB, TRUE, 8, $width, $height);
$pixbuf->get_from_drawable ($widget->window,
$widget->window->get_colormap(), 0, 0, 0, 0, $width, $height);
$pixbuf->save($filename,'bmp');
}
?>
Any other method that works on Vista and XP?
Thanks in advance.
Regards
