[0.5.7] — 2018-01-20

Added

  • .travis.yml, but failing on .to_image()

Changed

  • Move from defunct pycrypto to pycryptodome
  • Update pdfminer.six to 20170720

[0.5.6] — 2017-11-21

Fixed

  • Fix issue #41, in which PDF-object-referenced cropboxes/mediaboxes weren't being fully resolved.

[0.5.5] — 2017-05-10

Added

  • Access to __version__ from main namespace

Fixed

  • Fix issue #33, by checking decode_text's argument type

[0.5.4] — 2017-04-27

[0.5.3] — 2017-02-27

Fixed

  • Allow import pdfplumber even if ImageMagick not installed.

[0.5.2] — 2017-02-27

Added

  • Access to curve points. (E.g., page.curves[0]["points"].)
  • Ability for .draw_line to draw curve points.

Changed

  • Disaggregated "min_words_vertical" (default: 3) and "min_words_horizontal" (default: 1), removing "text_word_threshold".
  • Internally, made utils.decimalize a bit more robust; now throws errors on non-decimalizable items.
  • Now explicitly ignoring some (obscure) pdfminer object attributes.
  • Raw input for .draw_line from a bounding box to ((x, y), (x, y)), for consistency with curve["points"] and with Pillow's underlying method.

Fixed

  • Fixed typo bug when .rect_edges is called before .edges

[0.5.1] — 2017-02-26

Added

  • Quick-draw PageImage methods: .draw_vline, .draw_vlines, .draw_hline, and .draw_hlines.
  • Boolean parameter keep_blank_chars for .extract_words(...) and TableFinder settings.

Changed

  • Increased default text_tolerance and intersection_tolerance TableFinder values from 1 to 3.

Fixed

  • Properly handle conversion of PDFs with transparency to pillow images.
  • Properly handle pandas DataFrames as inputs to multi-draw commands (e.g., PageImage.draw_rects(...)).

Changed

  • Entirely overhaul the table-extraction methods. Now based on Anssi Nurminen's master's thesis.
  • Disentangle .crop from .intersects_bbox and .within_bbox.
  • Change default x_tolerance and y_tolerance for word extraction from 5 to 3

Fixed

[0.4.3] - 2016-04-12

Changed

  • When extracting table cells, use chars' midpoints instead of top-points.

Fixed
