How does the server deliver pictures

[Zhangbecool]

I added an object and I want to add a picture type variable but I don't know how to submit the picture

Picture Type is abstract, you have to use ImageBMP, ImageGIF, ImageJPG or ImagePNG. They are just ByteStrings => Python bytes.
image = b'0x123455'

[Zhangbecool]

 `self.img = self.myobj.add_variable(idx, 'image', None, datatype=ua.ObjectIds.ImageJPG)
    with open('1.jpg', 'rb') as f:
        encode_img_info = base64.b64encode(f.read())
    self.img.set_value(encode_img_info)`

Is that what you mean

[oroulet]

no need for encoding, write the bytes directy

[Zhangbecool]

thank you it's working

[oroulet]

so read_value() and write_value() on the node

[Zhangbecool]

I mean, how to transfer pictures on the server side

[AndreasHeine]

transfer is client part!
