This article introduces the knowledge of "how to use Python to watermark pictures". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Introduction to filestools Library

Today to introduce you to the Python library, called filestools, developed by Xiao Xiaoming, directly use the following command, use after installation.

Pip install filestools-index-url= http://mirrors.aliyun.com/pypi/simple-U

This library integrates a total of 4 functions, and all 4 libraries have been migrated to the filestools library, so if you install this library, you can use all 4 functions, you just need to use the corresponding functions and import the corresponding modules respectively.

# watermark the image with from watermarker.marker import add_mark

The add_mark () method has a total of eight parameters. If you don't know how to view the parameters, you can enter the following command in jupyter notebook to view them.

The following is to show you the meaning of the eight parameters in the add_mark () method, as follows:

File: the photo to be watermarked

Mark: which words are used as watermarks

Out: where to save after adding the watermark

Color: color of the watermark font. Default color # 8B8B1B

Size: font size of the watermark. Default is 50.

Opacity: transparency of watermark fonts. Default is 0.15.

Space: the interval between watermark fonts. Default is 75 spaces.

Angle: the rotation angle of the watermark font, which defaults to 30 degrees. Next, we will add a watermark to the image with only one line of code.

One line of code to watermark the picture

The original picture looks like this:

Use the following line of code, just two lines of code:

From watermarker.marker import add_markadd_mark (file=r "aixin.jpg", out=r "C:\ Users\ Administrator\ Desktop\ practice", mark= "Life is too short, learn Python", opacity=0.2, angle=45, space=30)

The watermark looks like this:

Finally, I would like to explain to you the meaning of this line of code.

Add_mark (file=r "aixin.jpg", out=r "C:\ Users\ Administrator\ Desktop\ practice", mark= "Life is too short, learn Python", opacity=0.2, angle=45, space=30)

Meaning: add a watermark to the picture named aixin.jpg in the current working environment. The watermark word is Quick Learning Python, the transparency of the watermark is 0.2, the rotation angle of the watermark is 45 °, and the interval between the watermarks is 30 spaces. After adding the watermark, finally save the processed image in a specified directory.
