利用wxpython显示OpenCV图像

import wx, cv2
import numpy as np

# Start with a numpy array style image I‘ll call "source"

# convert the colorspace to RGB from cv2 standard BGR, ensure input is uint8
img = cv2.cvtColor(np.uint8(source), cv2.cv.CV_BGR2RGB) 

# get the height and width of the source image for buffer construction
h, w = img.shape[:2]

# make a wx style bitmap using the buffer converter
wxbmp = wx.BitmapFromBuffer(w, h, img)

# Example of how to use this to set a static bitmap element called "bitmap_1"
self.bitmap_1.SetBitmap(wxbmp)
