I have several images (PNG format) that I want to combine them into one image file in a grid structure (in such a way that I can set the No. of images shown in every row). Also, I want to add small empty space between images.
For example, assume that there are 7 images. And I want to set the No. of images shown in every row as 3. The general structure of the combined image will be:
Please let me know if you know a good way to do that (preferably using PIL/Pillow
or matplotlib
libraries). Thanks.

You can pass to the combine_images
function number of expected columns
, space
between images in pixels and the list of images
:
from PIL import Image
def combine_images(columns, space, images):
rows = len(images) // columns
if len(images) % columns:
rows = 1
width_max = max([Image.open(image).width for image in images])
height_max = max([Image.open(image).height for image in images])
background_width = width_max*columns (space*columns)-space
background_height = height_max*rows (space*rows)-space
background = Image.new('RGBA', (background_width, background_height), (255, 255, 255, 255))
x = 0
y = 0
for i, image in enumerate(images):
img = Image.open(image)
x_offset = int((width_max-img.width)/2)
y_offset = int((height_max-img.height)/2)
background.paste(img, (x x_offset, y y_offset))
x = width_max space
if (i 1) % columns == 0:
y = height_max space
x = 0
background.save('image.png')
combine_images(columns=3, space=20, images=['apple_PNG12507.png', 'banana_PNG838.png', 'blackberry_PNG45.png', 'cherry_PNG635.png', 'pear_PNG3466.png', 'plum_PNG8670.png', 'strawberry_PNG2595.png'])
Result for 7 images and 3 columns:
Result for 6 images and 2 columns:
