Image processing with PIL (Pillow)

I wrote an article about Image processing with ImageMagic before. This time, I would like to write about image processing using Python's PIL library.

I will use the image below (800 * 600) this time as well. resize_img.jpg

Image size adjustment

from PIL import Image

#Read an existing file
img = Image.open('testimg/bb8.jpg', 'r')
#Resize. Specify the width and height.
resize_img = img.resize((800,600))
#Save the image. Save the resized image.
resize_img.save('testimg/resize_img.jpg')

The above image to be processed this time is the one of (4032 * 3024) resized above!

rotation

rotate_img = img.rotate(45)

rotate_img.jpg

Now this! The end part is black when it is rotated. It's different from ImageMagic.

Side by side two images

def canvasimage(inimg1, inimg2, outimg):
	img1 = Image.open(inimg1, 'r')
	img2 = Image.open(inimg2, 'r')

	canvas = Image.new('RGB', (800, 1200), (255, 255, 255))

	canvas.paste(img1, (0, 0))
	canvas.paste(img2, (0, 600))

	canvas.save(outimg, 'JPEG')

Lined! !! !!

canvas_img.jpg

Question

How to prevent black from entering when rotating! Examine you.
