Create thumbnail by resizing image in Python
Sometimes we need to create thumbnails of certain size from image. In this post I show you how to create thumbnail by resizing image in Python. Here is the Python code for creating thumbnail / resizing an image: import Image def generate_and_save_thumbnail(imageFile, h, w, ext): image = Image.open(imageFile) image = image.resize((w, h), Image.ANTIALIAS) outFileLocation = "./images/" outFileName = "thumb" image.save(outFileLocation + outFileName + ext) # set the image file name here myImageFile = "myfile.jpg" # set the image file extension extension = ".jpg" # set height h = 200 # set width w = 200 generate_and_save_thumbnail(myImageFile, h, w, extension) The second argument of image.resize() is the filter. You have several options there: Image.ANTIALIAS Image.BICUBIC Image.BILINEAR Image.NEAREST Each uses different algorithm. For downsampling (reducing the size) you ...
