[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(...)).
