First, I have an issue with saving up every resized file with the same name to the same folder? Second, while running I can't understand if m t code works properly. Please, could you check if I am doing the resizing properly?Can't find a mistake in my code:
import glob
from PIL import Image
images = glob.glob("C:/Users/marialavrovskaa/Desktop/Images/*.png")
for image in images:
with open(image,"rb") as file:
img = Image.open(file)
imgResult = img.resize((800,800), resample = Image.BILINEAR)
imgResult.save('"C:/Users/marialavrovskaa/Desktop/Images/file_%d.jpg"', 'JPEG')
print("All good")
If you want to give the images a name with a consecutive number than you've to concatenate the file name and a counter:
image_no = 1
for image in images:
# [...]
name = 'C:/Users/marialavrovskaa/Desktop/Images/file_' + str(image_no) + '.jpg'
imgResult.save(name, 'JPEG')
image_no += 1
Since the format of the images is PNG and they should be stored as JPEG, the format has to be convert from RGBA to RGB, by .convert('RGB'). Note, storing a RGBA image to 'JPGE' would cause an error:
import glob
from PIL import Image
images = glob.glob("C:/Users/marialavrovskaa/Desktop/Images/*.png")
image_no = 1
for image in images:
with open(image,"rb") as file:
img = Image.open(file)
imgResult = img.resize((800,800), resample = Image.BILINEAR).convert('RGB')
name = 'C:/Users/marialavrovskaa/Desktop/Images/file_' + str(image_no) + '.jpg'
imgResult.save(name, 'JPEG')
image_no += 1
print("All good")
By the way, if the file name should by kept and the image just should be stored to a file with a different extension, then then extension can be split form the file by .splitext:
import os
imgResult = img.resize((800,800), resample = Image.BILINEAR).convert('RGB')
name = os.path.splitext(image)[0] + '.jpg'
imgResult.save(name, 'JPEG')
If you wan to store the fiel to a different path, with a different extension, then you've to extract the fiel name from the path.
See os.path. Split the path from the file name and extension by os.path.split(path), which returns a tuple of path and name.
e.g.
>>> import os
>>> os.path.split('c:/mydir/myfile.ext')
('c:/mydir', 'myfile.ext')
The split the file name and the extension by os.path.splitext(path):
>>> os.path.splitext('myfile.ext')
('myfile', '.ext')
Applied to your code this means, where file is the path, name and extension of the source image file:
import glob
from PIL import Image
images = glob.glob("C:/Users/marialavrovskaa/Desktop/Images/*.png")
image_no = 1
for image in images:
with open(image,"rb") as file:
img = Image.open(file)
imgResult = img.resize((800,800), resample = Image.BILINEAR).convert('RGB')
image_path_and_name = os.path.split(file)
image_name_and_ext = os.path.splitext(image_path_and_name[1])
name = image_name_and_ext[0] + '.png'
file_path = os.path.join(path, name)
imgResult.save(file_path , 'JPEG')
image_no += 1
print("All good")

Basically, I copied and paste a script, and merged it with other script, and now the script doesn't work, it says an error "NoneType object has no attribute save"Screenshot
And here's the script:
` from PIL import Image
import PIL
import os
from glob import glob
imgs = [y for x in os.walk(".") for y in glob(os.path.join(x[0], '*.png'))]
size = 32, 32
lastdir = None
for file in imgs:
img = Image.open(file)
img = img.thumbnail(size, resample=PIL.Image.NEAREST)
file = file.replace('img', 'icon', 1)
dir = os.path.dirname(file)
try:
os.makedirs(dir)
except:
pass
if dir!=lastdir:
print(dir)
lastdir = dir
img.save(file + ".png", "PNG")`
Resize various images on various directories and save them, but the images are not saving.
The thumbnail() method modifies its object rather than returning a new one. So, this line:
img = img.thumbnail(size, resample=PIL.Image.NEAREST)
should be:
img.thumbnail(size, resample=PIL.Image.NEAREST)
I am going to resize image file which located in Desktop with set of subfolder.
I try following command and it works without rename save new.
from PIL import Image
import os, sys
import glob
root_dir='./././Desktop/python/'
def resize():
for filename in glob.iglob(root_dir + '**/*.jpg', recursive=True):
print(filename)
im = Image.open(filename)
imResize = im.resize((450,600), Image.ANTIALIAS)
imResize.save(filename , 'JPEG', quality=90)
resize()
My question is how can I add the correct command to save the renewe resized image file with append 'f + _thumbnail' + .jpg?
E.g file1 > file1_thumbnail.jpg
I tried add followings to row print(filename) but show error.
f, e = os.path.splitext(path+item)
size = im.size
ratio = float(final_size) / max(size)
new_image_size = tuple([int(x*ratio) for x in size])
im = im.resize(new_image_size, Image.ANTIALIAS)
new_im = Image.new("RGB", (final_size, final_size))
new_im.paste(im, ((final_size-new_image_size[0])//2, (final_size-new_image_size[1])//2))
new_im.save(f + 'resized.jpg', 'JPEG', quality=90)
May I know how can fix it?
Many Thanks
You can use python slicing of strings for this -
You can modify your code to -
from PIL import Image
import os, sys
import glob
root_dir='./././Desktop/python/'
def resize():
for filename in glob.iglob(root_dir + '**/*.jpg', recursive=True):
print(filename)
im = Image.open(filename)
imResize = im.resize((450,600), Image.ANTIALIAS)
filename = filename[:-4] + " _thumbnail" + filename[-4:]
imResize.save(filename , 'JPEG', quality=90)
resize()
The ".jpg" can be sliced at the end.
I'm trynna get the train_img and ground truth img from directory './train_dataset/train_img_cropped' & './train_dataset/train_gt_cropped'. Next, I wanna save the both original image and flipped one with a '_0', '_1'tail on its name in directory './train_dataset/train_img_preprocessed' & './train_dataset/train_gt_preprocessed'. But there's an Error of changing names (file + "_0" or "_1") as an unknown file extension. Looks like somehow PIL recognizes _0, _1 as a extension. Is there anybody who can help me to save with changing the name?
import os
import os.path
import glob
from PIL import Image
def preprocess(img_path, save_path):
targetdir = img_path
files = os.listdir(targetdir)
format = [".png"]
for (path, dirs, files) in os.walk(targetdir):
for file, i in files:
if file.endswith(tuple(format)):
image = Image.open(path + "/" + file)
image.save(save_path + "/" + file)
flippedImage = image.transpose(Image.FLIP_LEFT_RIGHT)
flippedImage.save(save_path + "/" + file)
print(file + " successfully flipped!")
else:
print(path)
print("InValid", file)
if __name__ == "__main__":
train_img_cropped_path = './train_dataset/train_img_cropped'
train_img_preprocessed_path = './train_dataset/train_img_preprocessed'
train_gt_cropped_path = './train_dataset/train_gt_cropped'
train_gt_preprocessed_path = './train_dataset/train_gt_preprocessed'
preprocess(train_img_cropped_path, train_img_preprocessed_path)
preprocess(train_gt_cropped_path, train_gt_preprocessed_path)
Not sure if this answers your question, but why not save the image with a temporary name (something like a random alphanumeric string or uuid) and then use os.rename to change the name of the temp file with your desired name ending _0 or _1.
I am working on a robotics project in which a robot creates images in .pgm format (not camera images) continuously which I'm converting to .jpeg and saving to a directory. However, this directory keeps updating as more images keep getting added while I want to convert these images continuously in a video. I can already create a video from the images saved in one instance but what I want is to update the video continuously as a single file (streaming onto a URL) while images keep getting saved. Here is my code but it doesn't work in parallel for images as well as for videos. Anyone can help?

# remove .yaml files
directory = "/home/user/catkin_ws/src/ros_map/map_pgms"
files_in_directory = os.listdir(directory)
filtered_files = [file for file in files_in_directory if file.endswith(".yaml")]
for file in filtered_files:
path_to_file = os.path.join(directory, file)
os.remove(path_to_file)
def batch_image(in_dir, out_dir):
if not os.path.exists(out_dir):
print(out_dir, 'is not existed.')
os.mkdir(out_dir)

print(in_dir, 'is not existed.')
return -1

for files in glob.glob(in_dir + '/*'):
filepath, filename = os.path.split(files)
out_file = filename[0:9] + '.jpg'
# print(filepath,',',filename, ',', out_file)
im = Image.open(files)
new_path = os.path.join(out_dir, out_file)
print(count, ',', new_path)
count = count + 1
im.save(os.path.join(out_dir, out_file))

I'm in an introductory neural networking class so mind my ignorance. Also my first SO post.
I'm trying to resize some very highly resolved images within a dataset into 80x80p grayscale images in a new dataset. However, when I do this, I'd like to keep the filenames of each new image the same as the original image. The only way I know how to resave images into a new file is through a str(count) which isn't what I want. The filenames are important in creating a .csv file for my dataset later.
The only SO post I can find that is related is this:
Use original file name to save image
But the code suggested there didn't work - wasn't sure if I was going about it the wrong way.
import os
from PIL import Image
import imghdr
count=0
path1 = "/Users/..."
path2 = "/Users/..."
listing = os.listdir(path1)
for file in listing:
type = imghdr.what((path1 + file))
if type == "jpeg":
img = Image.open("/Users/..." +file).convert('LA')
img_resized = img.resize((80,80))
img_resized.save(path2 + str(count) + '.png')
count +=1
pass
pass
Reuse the original filename that you get from the for loop i.e. file
and, split it into filename and extension using os.path.splitext() like below:
import os
from PIL import Image
import imghdr
count=0
path1 = "/Users/..."
path2 = "/Users/..."
listing = os.listdir(path1)
for file in listing:
type = imghdr.what((path1 + file))
if type == "jpeg":
img = Image.open("/Users/..." +file).convert('LA')
img_resized = img.resize((80,80))
# splitting the original filename to remove extension
img_filename = os.path.splitext(file)[0]
img_resized.save(path2 + img_filename + '.png')
count +=1
pass
Another option, we can use python str's built-in split method to split the original filename by . and discard the extension.
import os
from PIL import Image
import imghdr
count=0
path1 = "/Users/..."
path2 = "/Users/..."
listing = os.listdir(path1)
for file in listing:
type = imghdr.what((path1 + file))
if type == "jpeg":
img = Image.open("/Users/..." +file).convert('LA')
img_resized = img.resize((80,80))
# splitting the original filename to remove extension
img_filename = file.split(".")[0]
img_resized.save(path2 + img_filename + '.png')
count +=1
pass
So, if an image has a name such as some_image.jpeg then, the img_filename will have a value some_image as we splitted by . and discarded .jpeg part of it.
NOTE: This option assumes the original_filename will not contain any . other than the extension.
I assume that image name is on path1. If so you can grap image name from there in this way:
x=path1.rsplit('/',1)[1]
We are splitting path1 on last slash and taking image name string via indexing.
