python 处理图像五

1、绘制文字并填充图像
2、图片混合blend

from PIL import Image, ImageDraw, ImageFont
import matplotlib.pyplot as plt
import numpy as np

font_size = 7
text = " 我 爱 你 "
img_path = "bgdj1.jpg"

img_raw = Image.open(img_path)
img_array = img_raw.load()

img_new = Image.new("RGB", img_raw.size, (100, 100, 100))# 生成一张空白图像，大小、背景 
draw = ImageDraw.Draw(img_new)
font = ImageFont.truetype('Dengl.ttf', font_size)#字体

# 生成器
def character_generator(text):
    while True:
        for i in range(len(text)):
            yield text[i]

ch_gen = character_generator(text)

for y in range(0, img_raw.size[1], font_size):
    for x in range(0, img_raw.size[0], font_size):
        draw.text((x, y), next(ch_gen), font=font, fill=img_array[x, y], direction=None)

img_new.convert('RGB').save("save.jpeg")#保存
plt.imshow(np.array(img_new))
plt.show()

from PIL import Image
import matplotlib.pyplot as plt
import numpy as np

img2 = Image.open("my.png")
img2 = img2.convert('RGB')

img1 = Image.open("bgdj1.jpg")
img1 = img1.convert('RGB')
img2 = img2.resize(img1.size)

#img = img1×0.7+img2×0.3
img = Image.blend(img1, img2, 0.3)


plt.imshow(np.array(img))
plt.show()
