Python uses a combination of loops to arrange and output images,

This example describes how to combine and output images in a ring form in python. Share it with you for your reference. The specific analysis is as follows:

This code can customize a blank canvas, and then arrange the specified images in a ring-like manner, using the pil library, you can use:
Pip install pil.

The Code is as follows:

Import math
From PIL import Image
Def arrangeImagesInCircle (masterImage, imagesToArrange ):
ImgWidth, imgHeight = masterImage. size
# We want the circle to be as large as possible.
# But the circle shouldn't extend all the way to the edge of the image.
# If we do that, then when we paste images onto the circle, those images will partially fall over the edge.
# So we reduce the diameter of the circle by the width/height of the widest/tallest image.
Diameter = min (
ImgWidth-max (img. size [0] for img in imagesToArrange ),
ImgHeight-max (img. size [1] for img in imagesToArrange)
)
Radius = diameter/2
CircleCenterX = imgWidth/2
CircleCenterY = imgHeight/2
Theta = 2 * math. pi/len (imagesToArrange)
For I in range (len (imagesToArrange )):
CurImg = imagesToArrange [I]
Angle = I * theta
Dx = int (radius * math. cos (angle ))
Dy = int (radius * math. sin (angle ))
# Dx and dy give the coordinates of where the center of our images wocould go.
# So we must subtract half the height/width of the image to find where their top-left corners shoshould be.
Pos = (
CircleCenterX + dx-curImg. size [0]/2,
CircleCenterY + dy-curImg. size [1]/2
)
MasterImage. paste (curImg, pos)
Img = Image. new ("RGB", (500,500), (255,255,255 ))
# The following three images are 3 50x50 pngs images. If you use an absolute path, replace it with your image path.
ImageFilenames = ["d:/www.jb51.net/images/1.png", "d:/www.jb51.net/images/2.png", "d:/www.jb51.net/images/3.png"] * 5
Images = [Image. open (filename) for filename in imageFilenames]
ArrangeImagesInCircle (img, images)
Img. save ("output.png ")
