how to set colored image

[angle2392]

Hello pyKinectAzure(s),

I am using parts of pyKinectAzure but "offline" on RGB and depth data. I recorded .jpeg images and .png images from a scene and want to pass it to a "Capture" object. There are some functions to pass images to a capture.

It works for me with depth data:

depth_im = cv2.imread("./depth.png",cv2.IMREAD_ANYDEPTH)
h, w = depth_im.shape
depth_image_np = np.array(depth_im)
#Convert numpy array to a ctypes array:
ctypes_data = depth_image_np.ctypes.data_as(ctypes.POINTER(ctypes.c_uint8))
 
depth_image_k4a = _k4a.k4a_image_t()
_k4a.VERIFY(_k4a.k4a_image_create_from_buffer(_k4atypes.K4A_IMAGE_FORMAT_DEPTH16, w, h, depth_image_np.nbytes//h, ctypes_data, depth_image_np.nbytes , None, None, depth_image_k4a)," failed!")
_k4a.k4a_capture_set_depth_image(capture_handle, depth_image_k4a)

However, it does not work for RGB data:

im = cv2.imread("./rgb.jpeg", cv2.IMREAD_COLOR)
h_im, w_im, c = im.shape
image_np = np.array(im).flatten()
ctypes_data_im = image_np.ctypes.data_as(ctypes.POINTER(ctypes.c_uint8))
	
color_image_k4a = _k4a.k4a_image_t()
_k4a.VERIFY(_k4a.k4a_image_create_from_buffer(_k4atypes.K4A_IMAGE_FORMAT_COLOR_MJPG, w_im, h_im, w_im, ctypes_data_im, image_np.nbytes, None, None, color_image_k4a)," failed!")
_k4a.k4a_capture_set_color_image(capture_handle, color_image_k4a)

What am I doing wrong? Any clue why it does not take the RGB data?

Thanks in advance!
