The scale() function is an inbuilt function in the Python Wand ImageMagick library which is used to change the image size by scaling each pixel value by given columns and rows.
Syntax:
scale(columns, rows)Parameters: This function accepts two parameters as mentioned above and defined below:
- columns: This parameter stores the number of columns to scale the image horizontally. It is in pixels.
- rows: This parameter stores the number of columns to scale the image vertically. It is in pixels.
Return Value: This function returns the Wand ImageMagick object.

Example 1:
Python3
# Import library from Image from wand.image import Image# Import the imagewith Image(filename ='../neveropen.png') as image: # Clone the image in order to process with image.clone() as scale: # Invoke scale function with threshold as 0.8 scale.scale(200, 100) # Save the image scale.save(filename ='scale1.jpg') |
Output:
Example 2:
Python3
# Import libraries from the wand from wand.image import Imagefrom wand.drawing import Drawingfrom wand.color import Colorwith Drawing() as draw: # Set Stroke color the circle to black draw.stroke_color = Color('black') # Set Width of the circle to 2 draw.stroke_width = 1 # Set the fill color to 'White (# FFFFFF)' draw.fill_color = Color('white') # Invoke Circle function with center at 50, 50 and radius 25 draw.circle((200, 200), # Center point (100, 100)) # Perimeter point # Set the font style draw.font = '../Helvetica.ttf' # Set the font size draw.font_size = 30 with Image(width = 400, height = 400, background = Color('# 45ff33')) as pic: # Set the text and its location draw.text(int(pic.width / 3), int(pic.height / 2), 'GeeksForGeeks !') # Draw the picture draw(pic) # Invoke scale function method with threshold 0.6 pic.scale(50, 100) # Save the image pic.save(filename ='scale2.jpg') |
