""" Converts a pdf filename into plain text.
Each value is specified not as an actual length, but as a proportion of the length
to the size of each character in question.
Parameters define layout analysis. In a PDF text is in several chunks of various types.
Text extraction needs to recover text chunks which ar regarded as continuous if
elements distance is closer than the char_margin (identified as M) and thus are
grouped into one block. Two lines are part of the same text if they are closer than
the line_margin (L). If the distance between two words is greater than the word_margin (W),
blank characters (spaces) shall be inserted as necessary to keep format.
Boxes flow (F) specifies how much a horizontal and vertical position of a text matters
when determining text flow order. The value should be within the range from -1.0
(only horizontal position matters) to +1.0 (only vertical position matters).
Keyword arguments:
fname -- PDF file name (string)
pages -- Set of pages to extract (set)
M -- char_margin (float)
L -- line_margin (float)
W -- word_margin (float)
F -- boxes_flow (float)
