Use PIL Image processing library , Add text watermark to the picture , The code is as follows ：
from PIL import Image, ImageDraw, ImageFont
def handle_img(input_img, output_img, text, font_size):
font = ImageFont.truetype('C:/Windows/fonts/Dengl.ttf', font_size)
img_in = Image.open(input_img)
img_array = img_in.load()
# Create drawing objects
draw = ImageDraw.Draw(img_in)
def text_generator(text):
while True:
for i in range(len(text)):
yield text[i]
text_gen = text_generator(text)
# Combine text and pictures into new pictures
for y in range(0, img_in.size[1], font_size):
for x in range(0, img_in.size[0], font_size):
# fill = img_array[x, y]
# Pink
fill = (250, 150, 210)
draw.text((x, y), next(text_gen), fill=fill, font=font)
# Output a new picture
img_in.save(output_img)
return output_img
