Python API

The Basic API

from papirus import Papirus

# The epaper screen object
screen = Papirus()

# Write a bitmap to the epaper screen
screen.display('./path/to/bmp/image')

# Perform a full update to the screen (slower)
screen.update()

# Update only the changed pixels (faster)
screen.partial_update()

# Change screen size
# SCREEN SIZES 1_44INCH | 1_9INCH | 2_0INCH | 2_6INCH | 2_7INCH
screen.set_size(papirus.2_7INCH)

The Text API

from papirus import PapirusText

text = PapirusText()

# Write text to the screen
# text.write(text)
text.write("hello world")

# Write text to the screen at selected point
# text.write(text, (x,y))
text.write("hello world", (10, 10) )

The Image API

from papirus import PapirusImage

image = PapirusImage()

# easy write image to screen
# image.write(path)
image.write('/path/to/image')

# write image to the screen with size and position
# image.write(path, width, (x,y))
image.write('/path/to/image', 20, (10, 10) )

Your python script must be running with root previlages update the screen and change sizes. This code will only allow the script to run as root

import os
import sys

user = os.getuid()
if user != 0:
    print "Please run script as root"
    sys.exit()
