[0.5.28] — 2021-05-08

Added

  • Add --laparams flag to CLI. (#407)

Changed

  • Change .convert_csv(...) to order objects first by page number, rather than object type. (#407)
  • Change .convert_csv(...), .convert_json(...), and CLI so that, by default, they returning all available object types, rather than those in a predefined default list. (#407)

Fixed

  • Fix .extract_text(...) so that it can accept generator objects as its main parameter. (#385) [h/t @alexreg]
  • Fix page-parsing so that LTAnno objects (which have no bounding-box coordinates) are not extracted. (Was only an issue when setting laparams.) (#388)

Development Changes

  • Add a python setup.py build sdist test to main GitHub action. (#365)

[0.5.26] — 2021-02-10

Added

  • Add Page.close/__enter__/__exit__ methods, by generalizing that behavior through the Container class (b1849f4)

  • Change Page.to_image()'s handling of alpha layer, to remove aliasing artifacts (#340) [h/t @arlyon]

[0.5.24] — 2020-10-20

Added

Changed

  • Change character attribute upright from int to bool (per original pdfminer.six representation) (1f87898)

Added

  • Add utils.resolve (non-recursive .resolve_all) (7a90630)

Changed

  • Remove pdfminer.from_path and pdfminer.load as deprecated; now pdfminer.open is the canonical way to load a PDF. (00e789b)
