All you need

• Certificate
  • Design a simple template on Canva
• Logo
  • If you want to add your logo to the template, get a transparent .png file of your logo like this.
• Font
  • A .ttf (True-Type Font) file like this, can simply be downloaded from here.
• Names
  • Finally, a list of names in a .txt format or a .csv format.

Pillow module

Using the pillow module to make changes.

• Calculating and declaring default values.

from PIL import Image, ImageFont, ImageDraw

'''Global Variables'''
FONT_FILE = ImageFont.truetype(r'resources/font/GreatVibes-Regular.ttf', 180)
FONT_COLOR = "#FFFFFF"

template = Image.open(r'resources/templates/template.png')
WIDTH, HEIGHT = template.size

• Placing the name on the certificate and saving to a different directory.

def make_certificates(name):
  '''Function to save certificates as a .png file
  Finding the width and height of the text. 
  Placing it in the center, then making some adjustments.
  Saving the certificates in a different directory.
  '''

  image_source = Image.open(r'resources/templates/template.png')
  draw = ImageDraw.Draw(image_source)
  name_width, name_height = draw.textsize(name, font=FONT_FILE)
  draw.text(((WIDTH - name_width) / 2, (HEIGHT - name_height) / 2 - 30), name, fill=FONT_COLOR, font=FONT_FILE)

  image_source.save("./out/" + name + ".png")
  print('Saving Certificate of:', name)

Logo

• Setting up the logo file to place in the template

# Adding the logo
logo = Image.open(r'resources/logo/logo.png')
logo_width, logo_height = logo.size

# Placing it in the top middle
logo_position = ((WIDTH - logo_width) // 2, (HEIGHT - logo_height) // 12)
image_source.paste(logo, logo_position, logo)

Names

• Using readlines() method with a .txt format.

names = []

with open('names.txt') as f:
    content = f.readlines()
    for item in content:
        names.append(item[:-1].title())

• Using pandas to read a .csv file.

import pandas
names = pandas.read_csv('names.csv', sep='#')
