datamatrix barcodes

this is a module to create a datamatrix barcode here are a few webistes used to create this:

arm barcodes work to be done

[ ] add necessary codes and text for barcodes
[ ] add text to the bottom of the barcode
[ ] ensure the text at the bottom has correct leading zeros
[ ] format that text so it is large enough and readable
[ ] center the text
[ ] remove the boarder from the barcode (probably just top and sides)
[ ] invert the image to be white on black
[ ] add code to name and save the image
[ ] resize the image to fit within a 1/2" circle
[ ] a 1/2" circle could be drawn on the image to ensure it fits
[ ] create a loop to create all of the barcodes necessary
[ ] find out how to combine all of the images into rows and columns
[ ] create loop to combine some images to a certain width
[ ] create loop to combine some images to a certain height
[ ] check to ensure it's not too wide and tall, correct for that
[ ] create silhouette template for cutting everything out
[ ] do test prints on the laser printer to ensure it looks good
[ ] test the template to ensure it work
[ ] clean everything up to ensure the techs can use it easily

payload barcodes work to be done

[ ] reuse the code above
[ ] create barcode with necessary codes imbedded
[ ] put necessary text to the right
[ ] get lockheed logo and add/overlay it on image
[ ] format the text to look nice
[ ] resize the image to fit on the handcontrollers
[ ] do test prints on the laser printer to ensure it looks good
[ ] test the template to ensure it work
[ ] clean everything up to ensure the techs can use it easily

this is only needed the first time to install the necessary libraries

import sys !{sys.executable} -m pip install pyStrich

insert the necessary information to create barcodes below



In [24]:

    
part_number = 'replace this with part number' # replace the part number (i.e. ASM-00180-00)
starting_serial_number = 12358    # insert the serial number. DO NOT USE A LEADING ZERO (i.e. 1928 not 01928)
serial_numbers_to_create = 100

# select from the menu above: Cell -> Run All

print(len(str(serial_start))) print(type(serial_start)) print('0'+str(serial_start))



In [25]:

    
# import all the necessary libraries to make the script work
from pystrich.datamatrix import DataMatrixEncoder
from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw



In [40]:

    
output = part_number + str(starting_serial_number) + str(serial_numbers_to_create)
encoder = DataMatrixEncoder(output)
encoder.save("datamatrix_test.png")
# print(encoder.get_ascii())



In [43]:

    
img = Image.open('datamatrix_test.png')
width, height = img.size
msg = "sample text"
draw = ImageDraw.Draw(img)
w, h = draw.textsize('0'+str(starting_serial_number))
draw.text((((width-w)/2),(height-h)),'0'+str(starting_serial_number))
img.show()
