Prerequisite : PIL_working-images-python
Given an Image directory, our program will create a new image directory based on given threshold size.
A simple Python3 function that inputs the path of python file, the threshold width in pixels and the threshold height in pixels, searches all the images present in that only directory and creates a new directory having filtered out all the images according the given threshold size, or resizes it to the given threshold width and height.
Steps to Follow :
1. Install necessary Libraries like PIL
2. Import libraries : PIL, shutil, os, os.path
3. Save the code as sizeFilter.py
4. Open Terminal (where the python file is present and run)-> python sizeFilter.py
Below is the Python3 implementation of above approach :
# Python3 program to Filtering Images # based on Size Attributes from PIL import Image from shutil import copyfile import os, os.path def filterImages(path, thresholdWidth, thresholdHeight): # Defining images array for # identifying only image files imgs = [] # List of possible images extensions # add if you want more valid_images = [".jpg", ".gif", ".png", ".tga", ".jpeg", ".PNG", ".JPG", ".JPEG"] # Storing all images in images array (imgs) for f in os.listdir(path): ext = os.path.splitext(f)[1] if ext.lower() not in valid_images: continue imgs.append(f) # Checking whether the filteredImages # directory exists or not directory = os.path.dirname('filteredImages' + path) if not os.path.exists(directory): os.makedirs(directory) # Defining filteredIMages array for # storing all the images we need filteredImages = [] for i in imgs: image = Image.open(os.path.join(path, i)) # Storing width and height of a image width, height = image.size # if only width exceeds the thresholdWidth if (width > thresholdWidth and height <= thresholdHeight): image.resize((thresholdWidth, (thresholdWidth * height) // width)).save(i) # if only height exceeds the thresholdHeight elif (width <= thresholdWidth and height > thresholdHeight): image.resize(((thresholdHeight * width) // height, thresholdHeight)).save(i) # if both the parameters exceeds # the threshold attributes elif (width > thresholdWidth and height > thresholdHeight): image.resize((thresholdWidth, thresholdHeight)).save(i) copyfile(os.path.join(path, i), os.path.join(path + '/filteredImages', i)) filteredImages.append(i) # returning the filteredImages array return filteredImages # Driver Code if __name__ == '__main__': filteredImages = [] # Enter the path of the python sizeFilter # file, the thresholdWidth(in pixels) and # thresholdHeight(in pixels) filteredImages = filterImages("/home/SahilKhosla/Desktop/Current Project", 1000, 1000) |
