Hello everyone, I am Kongkong star. In this article, I will share with you how to add text watermark to pictures through Python's PIL library .

1. What is PIL?

PIL is the abbreviation of Python Imaging Library, which is one of the commonly used image processing libraries in Python language. It provides a wealth of image processing functions, including operations such as opening, saving, cropping, rotating, and scaling, and supports multiple image formats.

2. Install PIL

pip install pillow

3. Check the PIL version

pip show pillow

Fourth, use the PIL library to add text watermarks to pictures

1. Import library

from PIL import Image, ImageDraw, ImageFont

2. Open the picture file

local = '/Users/kkstar/Downloads/video/pic/'
image = Image.open(local+"demo.jpg")

3. Create a new Draw object

draw = ImageDraw.Draw(image)

4. Set watermark text, font, size

text = '@空空star'
font = ImageFont.truetype('STHeitiMedium.ttc', size=80)

5. Set watermark color

5.1 Set color by name

# 通过名称设置颜色-黄色
color = 'yellow'

5.2 Set color by RGB value

# 通过RGB值设置颜色-红色
color = (255, 0, 0)

5.3 Set color by RGBA value

# 通过RGBA值设置颜色-白色
color = (255,255,255,0)

5.4 Set color by hexadecimal

# 通过十六进制设置颜色-绿色
color = '#6FE000'

6. Get the size of the watermark text

text_width, text_height = draw.textsize(text, font)

7. Set the watermark position

7.1 upper left

x = 30
y = 30

7.2 Bottom right

x = image.width-text_width-30
y = image.height-text_height-30

Adjust the x and y values ​​at other positions. This 30 is set by me like this, you can also adjust it according to your own preferences.

8. Add watermark

draw.text((x, y), text, font=font, fill=color)

9. Save the picture

image.save(local+'image_with_watermark.jpg')
