Bing背景特别漂亮，用脚本自动下载图片，并设置为桌面。
把图片说明，用水印写在图片上。
1.爬取图片代码
#!/usr/bin/python3
# ubuntu设置动态bing壁纸
# 安装PIL库 pip install Pillow
from PIL import Image, ImageDraw, ImageFont
import requests
import os, re, time
import platform
is_windows = False
if -1 != platform.platform().upper().find('WINDOWS'):
is_windows = True
if not is_windows:
save_dir = "/home/leon/pic/wallpaper/bing/"
else:
save_dir = "D:\\bing\\"
def set_desktop(pic_path):
cmd = "gsettings set org.gnome.desktop.background picture-uri file:" + pic_path
# 设置壁纸
ret = os.system(cmd)
if ret != 0:
print("os.system failed, now exit")
exit(-1)
# windows设置壁纸
if is_windows:
import win32gui,win32con,win32api
def set_desktop_windows(imagepath):
k=win32api.RegOpenKeyEx(win32con.HKEY_CURRENT_USER,"Control Panel\\Desktop",0,win32con.KEY_SET_VALUE)
win32api.RegSetValueEx(k,"WallpaperStyle",0,win32con.REG_SZ,"2")#2拉伸适应桌面，0桌面居中
win32api.RegSetValueEx(k,"TileWallpaper",0,win32con.REG_SZ,"0")
win32gui.SystemParametersInfo(win32con.SPI_SETDESKWALLPAPER,imagepath,1+2)
#获取今天的图片的url和copyright信息
def get_bing_info():
base_url = "/"
query_url = "HPImageArchive.aspx?format=js&idx=0&n=1"
r = requests.get(base_url + query_url)
image_url = base_url + r.json()["images"][0]["url"]
copyright = r.json()["images"][0]["copyright"]
copyright = re.sub(r'\(.*\)', '', copyright);
print(copyright)
return (image_url, copyright)
#下载图片
def down_pic(pic_url, save_dir):
t = time.localtime(time.time())
image_name = "{}{:0>2}{:0>2}.jpg".format(t.tm_year, t.tm_mon, t.tm_mday)
# image_name = re.sub(r'.*/', '', pic_url)
save_path = save_dir + image_name
print(save_path)
r = requests.get(pic_url)
file = open(save_path, "wb")
file.write(r.content)
file.close()
return save_path
#添加水印
def add_watermark(path, text):
new_path = path + ".watermark"
cmd = "convert {0} -font 文泉驿微米黑 -pointsize 30 -draw \"gravity south fill black text 0,72 '{1}' fill white text 1,71 '{1}' \" {2}".format(path, text, new_path)
#print(cmd)
os.system(cmd)
os.system("mv {} {}".format(new_path, path))
#通过python的PIL库添加水印
def add_watermark_by_PIL(path, text):
img = Image.open(path)
mode = img.mode
img_w, img_h = img.size
font_size = int(img_h / 35)
if len(mode) == 1: # L, 1
white = (255)
black = (0)
if len(mode) == 3: # RGB
white = (255, 255, 255)
black = (0,0,0)
if len(mode) == 4: # RGBA, CMYK
white = (255, 255, 255, 255)
black = (0,0,0,0)
# 计算text长度，好让文字居中
if not is_windows:
# 字体可能要改
# linux查看支持的汉字字体 # fc-list :lang=zh
try:
ft = ImageFont.truetype("DroidSansFallbackFull.ttf", font_size)
except:
ft = ImageFont.truetype("wqy-microhei.ttc", font_size)
else:
ft = ImageFont.truetype("C:\\Windows\\Fonts\\simkai.ttf", font_size) #楷体
font_w, font_h = ft.getsize(text)
start_px = int((img_w - font_w) / 2)
#开始添加水印，同时添加黑白水印，处理深色和浅色背景问题
draw = ImageDraw.Draw(img)
if is_windows:
margin_bottom = 60
else:
margin_bottom = 20
draw.text((start_px + 2, img_h - font_size - margin_bottom + 2), text, black, font=ft)
draw.text((start_px, img_h - font_size - margin_bottom), text, white, font=ft)
img.save(path)
def main():
url, copyright = get_bing_info()
path = down_pic(url, save_dir)
if not is_windows:
add_watermark(path, copyright)
set_desktop(path)
else:
add_watermark_by_PIL(path, copyright)
set_desktop_windows(path)
main()
2.运行脚本
写一个bat文件。
C:\ProgramData\Anaconda3\python.exe C:\change_desktop.py %*
其中 'C:\ProgramData\Anaconda3\python.exe' 为python路径，'C:\change_desktop.py'为脚本路径。
3.自动启动
将bat文件放到开始菜单的启动下即可。
注：如果运行报错，需要在D盘下建一个bing文件。当然也可以在代码中修改。
