How to use PIL library for text watermark on an image?.

For the draw text watermark on an image, we have to use the PIL library. In PIL library there is various method but we are going to use a few of them like image open method, show method, image save method and image paste method.

now 1st we have to import PIL  library:

#import PIL library to use image relared functionality.
from PIL import Image
from PIL import ImageDraw
from PIL import ImageFont

Create a function which takes some parameters and perform some operations:

#Create a function to perform all operation
def picture_watermark(path_of_input_image,path_of_output_image,Text,position):

now we going to use all in-built function of PIL library:

    #Image.open function used to open the image
    Image1 = Image.open(path_of_input_image)
    Draw=ImageDraw.Draw(Image1)
    #text color
    black(3,8,12)
    font=ImageFont.truetype("Pillow/Tests/fonts/FreeMono.ttf",40)
    drawing.text(position,Text,fill=black,font=font)
    #show() inbuilt function is used to display the image
    Image1.show()
    Image1.save(path_of_output_image)

At last call the picture_watermark function by passing all required parameters:

 
if _name_ == '_main_':
    #Take path of image
    image1 = 'lighthouse.jpg'
    #call picture_watermark function by passing 4 parameters. 
    picture_watermark(image1, 'newimage.jpg','www.mousevspython.com', position=(0,0))

now combine the whole program we get:

#import PIL library to use image relared functionality.
from PIL import Image
from PIL import ImageDraw
from PIL import ImageFont
#Create a function to perform all operation
def picture_watermark(path_of_input_image,path_of_output_image,Text,position):
    #Image.open finction used to open the image
    Image1 = Image.open(path_of_input_image)
    print("original image ")
    Draw=ImageDraw.Draw(Image1)   
    #text color
    black(3,8,12)
    font=ImageFont.truetype("Pillow/Tests/fonts/FreeMono.ttf",40) 
    drawing.text(position,Watermark_Text,fill=black,font=font) 
    #show() inbuilt function is used to display the image
    Image1.show()
    Image1.save(path_of_output_image)
 
if _name_ == '_main_':
#Take path of image
image1 = 'lighthouse.jpg' 
#call picture_watermark function by passing 4 parameters. 
picture_watermark(image1, 'newimage.jpg','www.mousevspython.com', position=(0,0))
print("text watermarked image ........")

 

Output:

original image:

text watermarked image ……..
