def __init__(self):
wx.Frame.__init__(self,None,-1,'camera')
self.SetClientSize((640,480))
self.cap = cvCreateCameraCapture(0)
self.Bind(wx.EVT_IDLE,self.onIdle)
def onIdle(self,event):
img = cvQueryFrame(self.cap)
self.displayImage(img)
event.RequestMore()
def displayImage(self,img,offset=(0,0)):
bitmap = wx.BitmapFromBuffer(img.width,img.height,img.imageData)
dc = wx.ClientDC(self)
dc.DrawBitmap(bitmap,offset[0],offset[1],False)
if __name__ == '__main__':
app = wx.App()
frame = MyFrame()
frame.Show(True)
