This gets around a wrinkle in the memory management which would otherwise require us to manually clean up the pixbuf object when we’re done with it.

We don’t display the pixbuf directly but instead display a copy of it.

the number of channels times the width in pixels). frame.shape is the image width and frame.shape is the image height, and the last argument is the number of bytes in one row of the image (ie. The False argument is to say there is no alpha channel. We then use _from_data to convert this to a pixbuf.

To get the data into a form that GtkImage understands, we first convert the numpy ndarray to a byte array using.OpenCV natively generates BGR, not RGB, so even to display colour you need to do a conversion. GTK+ can apparently only handle the RGB colourspace, so you need to end up there one way or another. To convert to greyscale, I first convert BGR to greyscale and then greyscale to RGB.I’m resizing the video to twice it’s native resolution.Otherwise it can be quite difficult to kill the program (Ctrl+C doesn’t work try Ctrl+Z and then kill -9 %1). It’s quite important to handle the window’s delete_event signal.Note that the developers are all Americans and so spell ‘grey’ and ‘colour’ wrong.įrom gi.repository import Gtk, Gdk, GLib, GdkPixbufįrame = cv2.resize(frame, None, fx=2, fy=2, interpolation = cv2.INTER_CUBIC)įrame = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)įrame = cv2.cvtColor(frame, cv2.COLOR_GRAY2RGB)įrame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB) I’ve also added a button to switch between greyscale and colour. Each frame, we’ll replace the GtkImage’s image data with the frame from the camera. The main thing to note here is that we’re using a GtkImage object to display the video.

Here’s code that takes an OpenCV feed from a webcam and displays it in a Glade UI. Once you’ve found the documentation, it’s pretty easy to use. What’s really really dumb about it is calling it ‘gi’. Any new GObject-based library that’s written is immediately available in Python. What it does is pretty cool – it can expose any GObject-based library in Python. What we have now is called GObject Introspection – or ‘gi’. Time was, to use GTK in Python you installed PyGTK. Since it’s not at all obvious even where to find the documentation, I’m writing it down here.

Zipimport.I’ve just spent an hour or so figuring out how to display an OpenCV image in a GTK+ 3 window that’s created through a Glade UI using Python 3.

I'm trying to install Tensorflow for python 3.5 using pip3 - for reasons described in this github issue - but when I install using sudo pip3 install *.whl it installs to python 3.4.
