Image Resize

Background

I wanted to create my own sticker pack in Telegram. But the Telegram Bot have a dimenssion requirements where it needs either side of the images to be 512px.

The problem is all images are in all different dimensions and it is a trouble to manually change the dimensions to fit the 512px requirements.

Hence I codeed a python script to do all the adjustments automatically

The Code

from PIL import Image
import os 

os.chdir("image") # create a image file 

for each in os.listdir():
    if each.endswith("jpg") or each.endswith("JPG") or each.endswith("png") or each.endswith("PNG"):
        photo = Image.open(each)
        length=photo.size[0]
        width=photo.size[1]

        if length > width:
            ratio = length/512
            new_length=512
            new_width=round(width/ratio)

        else:
            ratio = width/512
            new_width=512
            new_length=round(length/ratio)

        photo= photo.resize((new_length,new_width), Image.ANTIALIAS)
        photo.save('mini' + each, quality =95)

Explanation

• Mainly it is the PIL packages
• The script will loop through all the files in a dir called image and find any files that is JPG or PNG
• Then it will get the length and width of the image
• Find the longer end will be down size to 512 and the shorter end will be down to the respective length ratio and the whole image will be saved with a new name mini together with the old name
