I am trying to horizontally combine some JPEG images in Python.
I have 3 images - each is 148 x 95 - see attached. I just made 3 copies of the same image - that is why they are the same.
I am trying to horizontally join them using the following code:
import sys
from PIL import Image
list_im = ['Test1.jpg','Test2.jpg','Test3.jpg']
new_im = Image.new('RGB', (444,95)) #creates a new empty image, RGB mode, and size 444 by 95
for elem in list_im:
for i in xrange(0,444,95):
im=Image.open(elem)
new_im.paste(im, (i,0))
new_im.save('test.jpg')
However, this is producing the output attached as test.jpg
.
Is there a way to horizontally concatenate these images such that the sub-images in test.jpg do not have an extra partial image showing?
I am looking for a way to horizontally concatenate n images. I would like to use this code generally so I would prefer to:
You can do something like this:
import sys
from PIL import Image
images = [Image.open(x) for x in ['Test1.jpg', 'Test2.jpg', 'Test3.jpg']]
widths, heights = zip(*(i.size for i in images))
total_width = sum(widths)
max_height = max(heights)
new_im = Image.new('RGB', (total_width, max_height))
x_offset = 0
for im in images:
new_im.paste(im, (x_offset,0))
x_offset += im.size[0]
new_im.save('test.jpg')
Test1.jpg
Test2.jpg
Test3.jpg
test.jpg
The nested for for i in xrange(0,444,95):
is pasting each image 5 times, staggered 95 pixels apart. Each outer loop iteration pasting over the previous.
for elem in list_im:
for i in xrange(0,444,95):
im=Image.open(elem)
new_im.paste(im, (i,0))
new_im.save('new_' + elem + '.jpg')
