[Interest] Using Qt Webengine to render to an image

[Kevin Mcintyre]

I do using pyqt.  Sometimes it's necessary to use QWebChannel to set
additional params like clipping properties.

class App(QApplication):

    def initCapture(self):
        self.capture = True
        self.opengl = None

    def toImage(self, location = None):
        png = '/tmp/capture.png'
        if location:
            png = location
        print 'toImage:', location
        if not self.opengl:
            print 'no opengl'
            return
        print 'IMAGE CAPTURE', png, self.opengl
        self.opengl.grabFramebuffer().save(png, 'PNG')


    def notify(self, receiver, event):
        if self.capture and isinstance(receiver, QOpenGLWidget):
            if self.opengl is None or self.opengl != receiver:
                #print '    SET OPENGL:', receiver
                self.opengl = receiver
        return super(App, self).notify(receiver, event)
