In this specific article we will learn how to read our image through Python wand module. To read image in Wand we use Image() function. To manipulate an image first of all we need to read image in Python.
Parameters :
Parameter Input Type Description image Image make exact copy of image blob bytes opens an image of blob byte array file object opens an image of the file object filename basestring opens image from filename width numbers.Integral the width of anew blank image or an image loaded from raw data height numbers.Integral the height of a new blank image or an image loaded from raw data depth numbers.Integral the depth used when loading raw data. background wand.color.Color an optional background color. colorspace basestring sets the stack’s default colorspace value before reading any images. units basestring paired with resolution for defining an image’s pixel density.
Now we will write a code to print height and width of image.
Code :
# import required libraries from __future__ import print_function from wand.image import Image # read image using Image() function img = Image(filename ='koala.jpg') # print height of image print('height =', img.height) # print width of image print('width = ', img.width) |
Output :
height = 300 width = 400
We can also read image from a url using urlopen function from urllib2 generic python library. Let’s see code to print image height and width read from a url.
# import required libraries from __future__ import print_function from urllib2 import urlopen from wand.image import Image try: # read image using Image() function img = Image(file = response) # print height of image print('Height =', img.height) # print width of image print('Width =', img.width) finally: response.close() |
