Hello Python community :)
I'm trying to write a python script using Pillow :
count files ( png images ) number create an image for every 64 images. example: if the folder containing 640 images, I will get 10 images as a thumbnail of 64 images/outputimage
just, before adding "for" instruction, I can get a result, but manually and only with the same image ( a duplication of image).
any idea?
I started by this step :
by the way, the png folder contains images named from 0.png to 640.png
I appreciate if you could take a look at this issue.
Thank you in advance.

I started by this step :
import os import os.path from PIL import Image def drange(start, stop, step): while start < stop: yield start start += step list = os.listdir(".") # directory path number_files = len(list) print (number_files) new_im = Image.new('RGB', (800, 800)) for x in drange(0, number_files, 64): im = Image.open(list[x]) im.thumbnail((100, 100)) for i in xrange(0, 800, 100): for j in xrange(0, 800, 100): new_im.paste(im, (i, j)) new_im.save(os.path.expanduser('out.png'))someone suggest me another solution :
import os.path from PIL import Image image_files = os.listdir(".") n_files = len(image_files) target_img = None n_targets = 0 collage_saved = False for n in range(n_files): img = Image.open(image_files[n]) img.thumbnail((100, 100)) if n % 64 == 0: # create an empty image for a collage target_img = Image.new("RGB", (800, 800)) n_targets += 1 collage_saved = False # paste the image at the correct position i = int(n / 8) j = n % 8 target_img.paste(img, (100*i, 100*j)) if (n + 1) % 64 == 0 and target_img is not None: # save a finished 8x8 collage target_img.save("{0:04}.png".format(n_targets)) collage_saved = True # save the last collage if not collage_saved: target_img.save("{0:04}.png".format(n_targets))so I modified his solution in order to run the script outside png folder :
import os.path from PIL import Image fileList = [] where_to_look = "png/" for f in os.listdir(where_to_look): if os.path.isfile(os.path.join(where_to_look, f)): fileList.append(f) print (len(fileList)) target_img = None n_targets = 0 collage_saved = False for n in range(len(fileList)): img = Image.open(fileList[n]) img.thumbnail((100, 100)) if n % 64 == 0: # create an empty image for a collage target_img = Image.new("RGB", (800, 800)) n_targets += 1 collage_saved = False # paste the image at the correct position i = int(n / 8) j = n % 8 target_img.paste(img, (100*i, 100*j)) if (n + 1) % 64 == 0 and target_img is not None: # save a finished 8x8 collage target_img.save("{0:04}.png".format(n_targets)) collage_saved = True # save the last collage if not collage_saved: target_img.save("{0:04}.png".format(n_targets))when I tested this script, I got :
Quote:Traceback (most recent call last):
File "combine.py", line 71, in <module>
img = Image.open(fileList[n])
File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 2258, in open
fp = builtins.open(filename, "rb")
IOError: [Errno 2] No such file or directory: '28.png'
by the way, the png folder contains images named from 0.png to 640.png
I appreciate if you could take a look at this issue.
Thank you in advance.
