"""
Created by Biswakalyan Bhuyan
Registration number:18BCB0038
This is a python3 script reads the data of the members from a csv file and images saved as name of the respective members.
Output is saved in output/ with png at output/png/ and pdf at output/pdf/
-->I have included placeholder profile pictures (of lego faces, obviously) at dataset/images/ as the name of the respective members<--
Python Modules required:
1.img2pdf
2.PIL (Pillow)
