I have created a small python script to generate a bunch of QR Codes using pyqrcode and using PIL to write the QR code value just below the QR code. The text is being written to the image using the following code:

def writeText(img,text):
    img = Image.open(img)
    draw = ImageDraw.Draw(img)
    w,h = img.size

    font = ImageFont.truetype('/Library/Fonts/Arial Black.ttf',20)
    text_w,text_h = draw.textsize(text,font)

    draw.text(((w-text_w) // 2, h-text_h-12), text,font=font)

    img.save("new.png")

The output text on the image is not smooth (see image) and the edges are not smooth lines. How can I achieve a high quality text on the image. Any changes in the code?

Could not get a proper and clear solution from the link posted. – Aneesh Relan Dec 06 '16 at 14:08
Try to render the text on an imager bigger than your target size, then resizing it down to the original size using ANTIALIAS flag – kmaork Dec 06 '16 at 14:53
I have tried creating at about 700x700 px and then resizing it to about 210,210 but the text is almost same. – Aneesh Relan Dec 06 '16 at 15:48
Did you use the flag? – kmaork Dec 06 '16 at 17:21
Yes I did. `img = img.resize((w,h),Image.ANTIALIAS)` – Aneesh Relan Dec 06 '16 at 19:32
Try and create a bigger image. If it doesn't get better at all you know it's a problem in your code – kmaork Dec 07 '16 at 07:04
I tried creating it at 2100x2100 px and then resizing it to 210x210 px. But the text is nearly the same. Please check if any problem in code. – Aneesh Relan Dec 08 '16 at 10:29
post your new code then – kmaork Dec 08 '16 at 10:30
