This should save even more memory! # 2010-03-25 CW r4234 remove duplicate chunks for extend_cells; refactor to remove put_number_cell and put_blank_cell which essentially duplicated the code of put_cell # 2010-03-10 SJM r4222 Added reading of the PANE record. # 2010-03-10 SJM r4221 Preliminary work on "cooked" mag factors; use at own peril # 2010-03-01 SJM Reading SCL record # 2010-03-01 SJM Added ragged_rows functionality # 2009-08-23 SJM Reduced CPU time taken by parsing MULBLANK records. # 2009-08-18 SJM Used __slots__ and sharing to reduce memory consumed by Rowinfo instances # 2009-05-31 SJM Fixed problem with no CODEPAGE record on extremely minimal BIFF2.x 3rd-party file # 2009-04-27 SJM Integrated on_demand patch by Armando Serrano Lombillo # 2008-02-09 SJM Excel 2.0: build XFs on the fly from cell attributes # 2007-12-04 SJM Added support for Excel 2.x (BIFF2) files. # 2007-10-11 SJM Added missing entry for blank cell type to ctype_text # 2007-07-11 SJM Allow for BIFF2/3-style FORMAT record in BIFF4/8 file # 2007-04-22 SJM Remove experimental "trimming" facility. from __future__ import print_function from array import array from struct import unpack, calcsize from .biffh import * from .timemachine import * from .formula import dump_formula, decompile_formula, rangename2d, FMLA_TYPE_CELL, FMLA_TYPE_SHARED from .formatting import nearest_colour_index, Format DEBUG = 0 OBJ_MSO_DEBUG = 0 _WINDOW2_options = ( # Attribute names and initial values to use in case # a WINDOW2 record is not written.
