The solarize() function is an inbuilt function in the Python Wand ImageMagick library which is used to negate all pixels above the threshold level.
Syntax:
solarize(threshold, channel)Parameters: This function accepts two parameters as mentioned above and defined below:
- threshold: This parameter stores the threshold level from 0 to available quantum range.
- channel: This is an optional parameter which stores the available method.
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 solarize: # Invoke solarize function with threshold value 35 solarize.solarize(35) # Save the image solarize.save(filename ='solarize1.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 solarize function method with threshold value 60 and channel as 'green' pic.solarize(60, 'green') # Save the image pic.save(filename ='solarize2.jpg') |
