0.5.0 - 2017-06-24

Added

Changed

  • Handling of invalid glyphs is done using the special HexaPDF::Font::InvalidGlyph class
  • Configuration option ‘font.on_missing_glyph’; returns an invalid glyph instead of raising an error
  • Bounding box of TrueType glyphs without contours is set to [0, 0, 0, 0]

  • Use TrueType configuration option ‘font.true_type.unknown_format’ in all places where applicable
  • Allow passing a font object to HexaPDF::Content::Canvas#font
  • Handle invalid entry in TrueType format 4 cmap subtable encountered in the wild gracefully
  • Invalid positive descent values in font descriptors are now changed into negative ones by the validation feature
  • Allow specifying the page media box or a page format when adding a new page through HexaPDF::Document::Pages#add

Fixed

  • HexaPDF::Task::Dereference to work correctly when encountering invalid references
  • HexaPDF::Tokenizer and HexaPDF::Content::Tokenizer to parse a solitary plus sign
  • Usage of Strings instead of Symbols for AFM font kerning and ligature pairs
  • Processing the contents of form XObjects in case they don’t have a resources dictionary
  • Deletion of valid page node when optimizing page trees with the hexapdf optimize command
  • HexaPDF::Type::FontType0 to always wrap the descendant font even if it is a direct object

0.4.0 - 2017-03-19

Added

  • HexaPDF::Type::FontType0 and HexaPDF::Type::CIDFont for composite font support
  • Complete support for CMaps for use with composite fonts; the interface for HexaPDF::Font::CMap changed to accomodate this
  • CLI command hexapdf batch for batch execution of a single command for multiple input files
  • CLI option --verbose for more verbose output; also changed the default verbosity level to only display warnings and not informational messages
  • CLI option --quiet for suppressing additional and diagnostic output
  • CLI option --strict for enabling strict parsing and validation; also changed the default from strict to non-strict parsing/validation
  • CLI optimization option --optimize-fonts for optimizing embedded fonts
  • Method #word_spacing_applicable? to font types
  • Support for marked-content points and sequences in HexaPDF::Content::Canvas
  • Support for property lists in a page’s resource dictionary
  • Show file name and size in hexapdf info output
  • HexaPDF::Type::Font#font_file for getting the embedded font file
  • HexaPDF::Font::TrueType::Optimizer for optimizing TrueType fonts
  • Configuration option ‘filter.flate_memory’ for configuring memory use of the HexaPDF::Filter::FlateDecode filter
  • Method HexaPDF::Content::Canvas#show_glyphs_only for faster glyph showing without text matrix calculations
  • Methods for caching expensive computations of PDF objects (HexaPDF::Document#cache and others)

Changed

Fixed

  • Use of wrong glyph IDs for glyph width entries and unicode mapping for subset TrueType fonts
  • Invalid document reference when importing wrapped direct objects with HexaPDF::Importer
  • Invalid type of /DW key in CIDFont dictionary when embedding TrueType fonts
  • Caching problem in HexaPDF::Document::Fonts which lead to multiple instances of the same font
  • Bug in handling of word spacing with respect to offset calculations when showing or extracting text
  • Incorrect handling of page rotation values in hexapdf merge
  • Missing handling of certain rotation values in hexapdf modify
  • Removal of unused pages in hexapdf modify
  • Handling of invalid page numbers in CLI commands
  • Useless multiple extraction of the same image in hexapdf images
  • Type of /VP entry of HexaPDF::Type::Page
  • Parsing of inline images that contain the end-of-image marker
  • High memory usage due to not closing Zlib::Stream objects in HexaPDF::Filter::FlateDecode

0.3.0 - 2017-01-25

Added

  • TrueType font subsetting support
  • Image extraction ability to CLI via hexapdf images command
  • HexaPDF::Type::Image#write for writing an image XObject to an IO stream or file

  • Refactor CLI command classes to use specialized superclass HexaPDF::CLI::Command
  • Optimize parsing of PDF files for better performance and memory efficiency

Fixed

  • Serialization of self-referential, indirect PDF objects
  • Performance problem for hexapdf inspect --pages when inspecting huge files
  • TrueType compound glyph component offset calculation
  • Parsing of TrueType data type ‘fixed’
