ev3dev-lang-python, rpyc and PIL

Hi again! This is not a issue. I am working with rpyc. I need big fonts for lcd screen!

I got a beautiful example in ev3python (thanks @ndward!)

#!/usr/bin/env python3
from ev3dev.ev3 import *
from PIL import Image, ImageDraw, ImageFont  
from time import sleep

lcd = Screen()

f = ImageFont.truetype('/usr/share/fonts/truetype/msttcorefonts/Arial.ttf', 75)
lcd.draw.text((3,0), 'Hello', font=f)
lcd.draw.text((2,55), 'world', font=f)
lcd.update()

sleep(7)  # if run from Brickman, need time to see displayed image

The problem is ImageFont. How i can import the remote PIL module (and Image, ImageDraw, ImageFont)? is it possible? Any example? Any workaround?

P.S: I am considering seriously to use ev3dev and ev3dev lang python for robotic teaching. Interactive programming is so appealing… I only wish to get things done as simple as I can.

However i don´t know how upgrade to the last development version the ev3dev

Here is what I do to get the latest version installed (on EV3):

sudo apt-get remove python3-ev3dev
git clone https://github.com/rhempel/ev3dev-lang-python
cd ev3dev-lang-python
python3 setup.py bdist
sudo python3 setup.py install --force

If you are using the latest developement version of ev3dev-lang-python (soon to be released as 0.7.1), then you can use bitmap fonts distributed with the library (see #225 and http://python-ev3dev.readthedocs.io/en/latest/other.html#bitmap-fonts for more details). The following works for me:

import rpyc
conn = rpyc.classic.connect('ev3dev')
ev3 = conn.modules['ev3dev.ev3']
fonts = conn.modules['ev3dev.fonts']
s = ev3.Screen()
s.draw.text((10,10), 'Hello World', font = fonts.load('luBS14'))
s.update()

If you are working with the latest released version (0.7.0), you may still use @ndward’s example you referenced. The only change is that you need to import PIL.ImageFont remotely:

ImageFont = conn.modules['PIL.ImageFont']
f = ImageFont.truetype('/usr/share/fonts/truetype/msttcorefonts/Arial.ttf', 75) # EV3 path
s.draw.text((10,10), 'Hello World', font=f)
s.update()
