         mark="空空star",
         color="white",
         size=30,
         opacity=0.3,
         angle=45,
         space=75)

3. Effect

5. Parameter adjustment comparison

1. Watermark color

Summarize

Looking at marker.py, you can find that this watermark processing is based on the PIL library. You can also see the default value of the watermark font.

From the following code, you can also see the default values ​​of the relevant parameters.

def add_mark(file, mark, out="output", color="#8B8B1B", size=30, opacity=0.15, space=75, angle=30):
    if os.path.isdir(file):
        names = os.listdir(file)
        for name in names:
            image_file = os.path.join(file, name)
            add_mark2file(image_file, mark, out, color, size, opacity, space, angle)
    else:
        add_mark2file(file, mark, out, color, size, opacity, space, angle)
