i have made python program to make barcode and write on it by using python-barcode,PIL library now i use PIL to resize image then write on it example:

with image.open("namr"+".png") as img:
 img=img.resize((143,76),PIL.Image.LANCZOS)
img.save(file="file.png")

now i want the barcode to be in sticker 3.8×2 cm but when i resize barcode it pixelated i want it to be clear to be printed and scanned to be on products

i tried using Image.LANCZOS but didnt work
