0.8.15  2024-12-25T07:56:04+13:00

      text box to text style.
    - Select either \c[HYPEN] and \c[HYPHEN-MINUS] from fonts

0.8.14  2024-12-24T07:43:50+13:00
    - Handle partial and multiple space characters:
    \c[EN SPACE] \c[EM SPACE] \c[THIN SPACE] \c[HAIR SPACE]
    \c[THREE-PER-EM SPACE] \c[FOUR-PER-EM SPACE] \c[SIX-PER-EM SPACE]

0.8.13  2024-12-23T07:09:50+13:00
    - Handle zero width spaces.
    - Accept both \c[HYPEN] and \c[HYPHEN-MINUS] as a continuation
      hyphen in input text and for font rendering.

0.8.12  2024-12-09T07:07:11+13:00
    - Tweak current-point() for #28 and also to more faithfully follow
      the spec. Return and undefined list, if there's no current point,
      rather than (undef, undef).

0.8.11  2024-12-06T17:19:32+13:00
    - Handle "\c[HYPHENATION POINT]" characters in input text. They
      may converted to actual hyphens to facilitate line-breaking,
      but are otherwise ignored.
    - Tweak justification of partial lines. Add `:max-word-gap`
      option. Perform text block alignment early to facilitate
      introspection. Make line word-gap() into a read/write
      assessor to allow adjustments.

0.6.13  2023-08-02T13:02:41+12:00
   - Fixes to return positional values of Graphics .print and .say methods:
     my ($x0, $y0, $x1, $y1) = $gfx.print("text");
     -- Track and take account of current text flow in computing $x0, $x1:
        This is only an issue if the text is continuing the current line
     -- Add any :$baseline offset to $y0, $y1.

     the existing base-coords() method.
   - Added automatic font object loading from the content stream. See
     tests in t/text-box.t. Also requires PDF::Font::Loader.
   - Added type() and encoding() methods to core fonts for improved

0.6.4  2022-06-09T09:35:37+12:00
   - Convert ops to PDF 0.5.8+ :lite AST

0.6.3  2022-06-07T16:49:54+12:00
   - Adjust tests for PDF 0.5.8. Use PDF::COS::Util from-ast()
     sub in PDF::Content::Ops for proper encapsulation

   This release targets parallel thread-safe page construction
   - Bump dependents PDF and Font::AFM to thread-safe versions
   - Add PDF::Content::PageTree page-fragment() and pages-fragment() methods.
     These are individual pages or page-trees for concurrent composition.
     They can be built in parallel and in any order before being added
     sequentially using the add-page() method.
   - Make core-fonts and 'require' of classes thread safe. These seem to
     be the main internal areas of thread-safety contention

0.5.17  2022-03-25T08:53:53+13:00
   - Add text box Str() method

     PDF::Content::FontObj and scaled in PDF::Content::Text::Box. Available
     also in PDF::Font::Loader::FontObj v0.5.16+.
   - Add iterate-pages() method

0.5.11  2021-12-03T12:10:07+13:00

0.5.9  2021-10-12T17:38:03+13:00
  - Deprecate PDF::Content::Tags owner() in favour of canvas()

0.5.8  2021-10-08T14:36:22+13:00
  - Deprecate canvas(&code) for drawing to an HTML::Canvas in favour
    of html-canvas(&code).
  - canvas() method now returns the PDF::Content::Canvas containing
    object, either a Page, XObject Form or Pattern.

0.5.7  2021-10-02T08:19:46+13:00
  - Use PDF::Content v0.5.7+ PDF::Content::Canvas role for composing
    XObject Forms and Tiling Pattern classes

   - Fix PDF::Content do() positioning for XObject Forms
   - Changed PDF::Context::Text::Style handling of :$baseline option. Use
     font.ascender as top point, rather than font.bbox.y

0.5.5  2021-07-16T14:26:05+12:00
   - Added block form of paint() method. $gfx.paint(&code, |c)) is equivalent to
     $gfx.Save; code(gfx); $gfx.paint(|c); $gfx.Restore;
   - make page bbox() method order from bottom left corner. So a page with
     /MediaBox [ 0 0 612 -792 ] is returned as [0, -792, 612, 0]

0.5.4  2021-07-07T11:28:02+12:00
   PDF::Font::Loader v0.5.5+ compatibility:
   - Font decoding now has three stages decode($bytes, :cids), decode($bytes, :ords) and
     decode() [text-string, default].
   - Font encoding has two stages encode($text, :cids), encode($text) [byte-string, default].
   - type-check text-box() arguments. Make sure we've got a font dictionary
     or a font object

0.5.3  2021-07-02T13:37:20+12:00
  - Add cid-map-glyph() callback for PDF::Font::Loader

0.5.2  2021-06-23T13:43:44+12:00

  - Add PDF::Content::FontObj - interface role for font manipulation
    objects.
  - core-font() method now returns the font-object of type
    PDF::Content::FontObj, rather than font dictionary. This is for
    consistency with PDF::Font::Loader. This allows type-checking.
    Also, a font object is more likely to be useful to an end user.

  - Fix :WordSpacing option in text boxes #13

0.4.12  2021-03-11T11:35:37+13:00
  - Fix use-font() method to simply check for uniqueness of the font
    dictionary. The former (deep) equivalence check is incompatible
    with PDF::Font::Loader 0.4.0+, which builds font dictionaries lazily.
  - Add a current-point() accessor; valid during path construction

0.4.11  2021-02-08T16:42:42+13:00
  - Add matrix reflection method. Put its order to be applied
    after rotation and before skew.
  - Add requirement for Font::AFM version 1.24.4+.
  - Add tests for the new method.
  - Deprecate PDF::Content::Text::Block class in favor of
    PDF::Content::Text::Box and text-block() method in favour of
    text-block(). "Text blocks" already commonly refers to BeginText ..
    EndText regions in a content stream. Call them "text boxes" instead.

  - Fix paint() method use of ClosePath op
  - Fix nesting of text blocks in :trace output

  related tags only. Functionality exported to PDF::Tags (under
  construction).

  and /Image respectively.

Release 0.4.1
- .print() and .say() methods now always return block coordinates
- .tag() returns the return value of the executed block
