python-pillowHow to resize an image and maintain aspect ratio
from PIL import Image, ImageDraw, ImageFont
im = Image.open('/var/www/examples/heroine.png')
width = 100
height = width * im.size[1]/im.size[0]
im = im.resize((width, height))
im.show()ctrl + cPILimport Pillow package modules | Image.openopen given image with Pillow |
100resized image width | im.sizereturns original image width and height |
width * im.size[1]/im.size[0]calculates height so that aspect ratio is maintained | .resize(resizes given image to the specified size |
.show()displays resulting image | |
Usage example
from PIL import Image, ImageDraw, ImageFont
im = Image.open('/var/www/examples/heroine.png')
width = 150
height = round(width * im.size[1]/im.size[0])
im = im.resize((width, height))
im.show()
