Example 1:
Python3
# Import library from Image from wand.image import Image # Import the image with Image(filename = '../neveropen.png' ) as image: # Import the watermark image with Image(filename = 'wave1.jpg' ) as water: # Clone the image in order to process with image.clone() as watermark: # Invoke watermark function with watermark image, transparency as 0.5 # left as 10 and top as 20 watermark.watermark(water, 0.5 , 10 , 20 ) # Save the image watermark.save(filename = 'watermark1.jpg' ) |
Output:
Example 2:
Python3
# Import libraries from the wand from wand.image import Image from wand.drawing import Drawing from wand.color import Color with 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) # Import the watermark image with Image(filename = 'wave1.jpg' ) as water: # Invoke watermark function with watermark image, transparency as 0.5 # left as 10 and top as 20 pic.watermark(water, 0.5 , 10 , 20 ) # Save the image pic.save(filename = 'watermark2.jpg' ) |
