On reddit.com, many moons ago, I downloaded some code which generated
a page using HTML tables from a picture of the page you wanted.
However, I dont have any author information in the code and wanted to
stay in touch which she/he... does anyone know who wrote this code
below?
# Box geometry.
class Box(object):
def __init__(self, x, y, right, bottom):
self.x, self.y, self.right, self.bottom = x, y, right, bottom
def box_x_delimeters(boxes):
return sorted(set(box.right for box in boxes))
def box_y_delimiters(boxes):
return sorted(set(box.bottom for box in boxes))
def box_rowspans(boxes):
rowspans = dict((box, 0) for box in boxes)
for delim in box_y_delimiters(boxes):
for box in boxes:
if box.y < delim and box.bottom >= delim:
rowspans[box] += 1
return rowspans
def box_colspans(boxes):
colspans = dict((box, 0) for box in boxes)
for delim in box_x_delimeters(boxes):
for box in boxes:
if box.x < delim and box.right >= delim:
colspans[box] += 1
return colspans
def box_rows(boxes):
rows, boxes_left = [], set(boxes)
for delim in box_y_delimiters(boxes):
boxes_in_row = set(box for box in boxes_left if box.y < delim)
boxes_left -= boxes_in_row
rows.append(sorted(boxes_in_row, key=lambda box: box.x))
return rows
