apt-get install -y python-PIL

在图片右下角添加文字：

Python

# -*- coding: utf-8 -*-

from PIL import Image, ImageDraw, ImageFont

# 指定要使用的字体和大小；/Library/Fonts/是macOS字体目录；Linux的字体目录是/usr/share/fonts/

font = ImageFont.truetype('/usr/share/fonts/truetype/dejavu/DejaVuSerif.ttf', 24)

# image: 图片 text：要添加的文本 font：字体

def add_text_to_image(image, text, font=font):

rgba_image = image.convert('RGBA')

text_overlay = Image.new('RGBA', rgba_image.size, (255, 255, 255, 0))

image_draw = ImageDraw.Draw(text_overlay)

text_size_x, text_size_y = image_draw.textsize(text, font=font)

# 设置文本文字位置

print(rgba_image)

text_xy = (rgba_image.size[0] - text_size_x, rgba_image.size[1] - text_size_y)

# 设置文本颜色和透明度

image_draw.text(text_xy, text, font=font, fill=(76, 234, 124, 180))

image_with_text = Image.alpha_composite(rgba_image, text_overlay)

return image_with_text

im_before = Image.open("uouo123.jpg")

im_before.show()

im_after = add_text_to_image(im_before, 'blog.uouo123.com')

im_after.show()

# im.save('im_after.jpg')

添加图片水印：

Python

# -*- coding: utf-8 -*-

from PIL import Image, ImageDraw

defadd_watermark_to_image(image, watermark):

rgba_image = image.convert('RGBA')

rgba_watermark = watermark.convert('RGBA')

image_x, image_y = rgba_image.size

watermark_x, watermark_y = rgba_watermark.size

# 缩放图片

scale = 10

watermark_scale = max(image_x / (scale * watermark_x), image_y / (scale * watermark_y))

new_size = (int(watermark_x * watermark_scale), int(watermark_y * watermark_scale))

rgba_watermark = rgba_watermark.resize(new_size, resample=Image.ANTIALIAS)

# 透明度

rgba_watermark_mask = rgba_watermark.convert("L").point(lambda x: min(x, 180))

rgba_watermark.putalpha(rgba_watermark_mask)

watermark_x, watermark_y = rgba_watermark.size

# 水印位置

rgba_image.paste(rgba_watermark, (image_x - watermark_x, image_y - watermark_y), rgba_watermark_mask)

return rgba_image

im_before = Image.open("uouo123.jpg")

im_before.show()

im_watermark = Image.open("blog.jpg")

im_after = add_watermark_to_image(im_before, im_watermark)

im_after.show()

# im.save('im_after.jpg')
