Python写春联,这也太秀了吧!
用Python写春联,全部代码大约70行。代码中用到的字模均来源于网络,共计1550个常用汉字。
1.代码中需要导入的模块
import io
from PIL import Image
import numpy as np
import requests
2.下载字模
def get_word(ch, quality):
#"""获取单个汉字(字符)的图片
#ch - 单个汉字或英文字母(仅支持大写)
#quality - 单字分辨率,H-640像素,M-480像素,L-320像素
#"""
fp = io.BytesIO(requests.post(url='http://xufive.sdysit.com/tk', data={'ch':ch}).content)
im = Image.open(fp)
w, h = im.size
if quality == 'M':
w, h = int(w*0.75), int(0.75*h)
elif quality == 'L':
w, h = int(w*0.5), int(0.5*h)
return im.resize((w,h))
3.下载龙凤呈祥背景底图
def get_bg(quality):
#"""获取春联背景的图片"""
return get_word('bg', quality)
4.生成春联
def write_couplets(text, HorV='V', quality='L', out_file=None):
#"""生成春联
#text - 春联内容,以空格断行
#HorV - H-横排,V-竖排
#quality - 单字分辨率,H-640像素,M-480像素,L-320像素
#out_file - 输出文件名
#"""
usize = {'H':(640,23), 'M':(480,18), 'L':(320,12)}
bg_im = get_bg(quality)
text_list = [list(item) for item in text.split()]
rows = len(text_list)
cols = max([len(item) for item in text_list])
if HorV == 'V':
ow, oh = 40+rows*usize[quality][0]+(rows-1)*10, 40+cols*usize[quality][0]
else:
ow, oh = 40+cols*usize[quality][0], 40+rows*usize[quality][0]+(rows-1)*10
out_im = Image.new('RGBA', (ow, oh), '#f0f0f0')
for row in range(rows):
if HorV == 'V':
row_im = Image.new('RGBA', (usize[quality][0], cols*usize[quality][0]), 'white')
offset = (ow-(usize[quality][0]+10)*(row+1)-10, 20)
else:
row_im = Image.new('RGBA', (cols*usize[quality][0], usize[quality][0]), 'white')
offset = (20, 20+(usize[quality][0]+10)*row)
for col, ch in enumerate(text_list[row]):
if HorV == 'V':
pos = (0, col*usize[quality][0])
else:
pos = (col*usize[quality][0],0)
ch_im = get_word(ch, quality)
row_im.paste(bg_im, pos)
row_im.paste(ch_im, (pos[0]+usize[quality][1], pos[1]+usize[quality][1]), mask=ch_im)
out_im.paste(row_im, offset)
if out_file:
out_im.convert('RGB').save(out_file)
out_im.show()
5.测试样例
5.1 普天同庆 欢度春节
text = '普天同庆 欢度春节'
write_couplets(text, HorV='V', quality='M', out_file='普天同庆.jpg')12
5.2 年尽岁除岁月如歌 冬去春来春光似画
text = '年尽岁除岁月如歌 冬去春来春光似画'
write_couplets(text, HorV='H', quality='M', out_file='岁月如歌.jpg')
5.3 人世间纵有百娇千红 唯独你是我情之所钟
text = '人世间纵有百娇千红 唯独你是我情之所钟'
write_couplets(text, HorV='H', quality='M', out_file='情之所钟.jpg')
