Script to scrape the hi-res tiles of a painting from tretyakovgallery.ru

tretyakov.py

from bs4 import BeautifulSoup
import urllib.request
from PIL import Image

base_url = "http://www.tretyakovgallery.ru/"

with open('table.txt') as f:
	html = f.read()

soup = BeautifulSoup(html)

urls = []

for row in soup.find_all('tr'):
	row_urls = []
	
	for tile in row.find_all('td'):
		style = tile['style']
		url = style[style.find("(")+2:style.find(")")-1]
		row_urls.append(url)
	urls.append(row_urls)

for i in range(len(urls)):
	print(i)
	for j in range(len(urls[0])):
		print(j)
		urllib.request.urlretrieve(base_url + urls[i][j], "img/"+str(i)+"_"+str(j)+".jpg")

xs = len(urls[0])
ys = len(urls)

imgs = []

for i in range(ys):
	row = []
	for j in range(xs):
		row.append(Image.open("img/"+str(i)+"_"+str(j)+".jpg"))
	imgs.append(row)

y_max = 0
for i in range(ys):
	y_max += imgs[i][0].size[1]

x_max = 0
for j in range(xs):
	x_max += imgs[0][j].size[0]

out = Image.new('RGB', (x_max, y_max))

y = 0
for i in range(ys):
	x = 0
	for j in range(xs):
		out.paste(imgs[i][j], (x,y))
		x += imgs[i][j].size[0]
	y += imgs[i][0].size[1]

out.save("out.jpg")

Usage:

1. Go to the painting you want to download, eg. http://www.tretyakovgallery.ru/en/collection/_show/image/_id/252
2. Click on the image to bring up zoomed-in popup
3. Right-click on the popup, then 'Inspect element'
4. Scroll up to the first <tbody> tag you see. Right click it, and then 'Copy inner HTML'
5. Paste what you just copied into a file called 'table.txt'
6. Run the script in the same directory as table.txt
