There is imagegrabscreen() and imagegrabwindow(), which would allow you to programmatically create screenshots from a browser running on the same machine via COM (Win only though). See the comments in the manual for how to omit the browser’s chrome. With DCOM enabled, this would also work with remote windows machines that have been setup to … Read more
First you’ll need to add references for the following namespaces: using System.Drawing; using System.Drawing.Imaging; using System.Windows.Forms; Then enumerate your monitors to get the bounding rectangle for all display surfaces and pass that in to the Graphics.CopyFromScreen() method call: private static BitmapSource CopyScreen() { var left = Screen.AllScreens.Min(screen => screen.Bounds.X); var top = Screen.AllScreens.Min(screen => screen.Bounds.Y); … Read more
You should use it this way: $(‘body’).html2canvas(); var queue = html2canvas.Parse(); var canvas = html2canvas.Renderer(queue,{elements:{length:1}}); var img = canvas.toDataURL(); window.open(img); It took me few hours to figure it out, how to use it the right way. The {elements:{length:1}} is required, due to incomplete implementation of the plugin, otherwise you’ll get an error. Good luck!
This piece of code captures the OpenGL window and export to a BMP file. You must have FreeImage library to run it. // Make the BYTE array, factor of 3 because it’s RBG. BYTE* pixels = new BYTE[3 * width * height]; glReadPixels(0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, pixels); // Convert to FreeImage format & … Read more
Most streaming media services now make use of EME https://en.wikipedia.org/wiki/Encrypted_Media_Extensions. The media players built by these services make use of EME to invoke the underlying DRM (Digital Rights Management) WebBrowser -> HTML5/Javascript -> EME -> DRM And yes, of course you can build your own solution using EME.
It’s just as simple as command+s or File > Save Screen Shot in iOS Simulator. It will appear on your desktop by default.
The immediate idea that comes to mind is to use java.awt.Robot to capture a screen shot, paint that to frameless window. From there you can simply draw a rectangle on it Updated with example … Took some time … public class SelectionRectangle { public static void main(String[] args) { new SelectionRectangle(); } public SelectionRectangle() { … Read more
Here’s how you can do it using PIL on win32. Given a window handle (hwnd), you should only need the last 4 lines of code. The preceding simply search for a window with “firefox” in the title. Since PIL’s source is available, you should be able to poke around the ImageGrab.grab(bbox) method and figure out … Read more
New API has been added since iOS 7, that should provide efficient way of getting snapshot snapshotViewAfterScreenUpdates: renders the view into a UIView with unmodifiable content resizableSnapshotViewFromRect:afterScreenUpdates:withCapInsets : same thing, but with resizable insets drawViewHierarchyInRect:afterScreenUpdates: : same thing if you need all subviews to be drawn too (like labels, buttons…) You can use the UIView … Read more
If you have GTK, then you can use the gtk.gdk.Display class to do most of the work. It controls the keyboard/mouse pointer grabs a set of gtk.gdk.Screen objects.
