(1)first i new an (512,512,3) zeros array,like this: bgr = np.zeros((512,512,3),dtype=np.int)
(2)then i process every pixels like this: for j in range(512): for i in range(512): bgr[i][j][0] = b[0][i][j] bgr[i][j][1] = g[0][i][j] bgr[i][j][2] = r[0][i][j]
(3)at last i use imshow("image",bgr) to show the image. but there is nothing
(4)at the same time, i use imwrite("image.jpg",bgr),the file writed right.
