First crop operation is performed and then resize operation. Syntax : wand.image.transform(crop='', resize='') Parameters : Parameter Input Type Description crop basestring A geometry string defining a subregion of the image to crop to resize basestring A geometry string defining the final size of the image Input Image: Example #1: Let us take an image crop it in dimensions 200x200 and then rescale it to 400x400 pixels. Python3 1== # Import Image from wand.image module from wand.image import Image # Import display to display final image from wand.display import display # Read image using Image function with Image(filename ='koala.jpeg') as img: # using transform() function img.transform('200x200', '200 %') # Saving image img.save(filename ='transform.jpeg') # display image display(img) Output: Example #2: Let us take an image crop 50 % of all four corners. Python3 1== # Import Image from wand.image module from wand.image import Image # Import display to display final image from wand.display import display # Read image using Image function with Image(filename ='koala.jpeg') as img: # using transform() function img.transform('50 %') # Saving image img.save(filename ='transform1.jpeg') # display image display(img) Output: Example #3: Scale height of source image to 200px and preserve aspect ratio. Python3 1== # Import Image from wand.image module from wand.image import Image # Import display to display final image from wand.display import display # Read image using Image function with Image(filename ='koala.jpeg') as img: # using transform() function img.transform(resize ='x200') # Saving image img.save(filename ='transform3.jpeg') # display image display(img) Output: Create Quiz Comment R RahulSabharwal Follow 0 Improve R RahulSabharwal Follow 0 Improve Article Tags : Python Image-Processing Python-wand Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
