Packaging changes.
0.032 2023-11-01
Pluggable elements extend parsing and rendering of elements.
A pluggable element is used to implement the <img> element, to
include images inline in text strings.
See tests/im1.pl and tests/im3.pl for examples.
Rise may now also take an 'em' or 'ex' value. 1em = 100%, 1ex = 50%.
0.031 2023-05-29
Improve bounding box and line spacing determination by using the
font ascender and descender values only.
Allow ascender and decender to be overruled in the font config.
Adapt some of the example programs to run on Microsoft Windows.
0.030 2022-09-03
Enable xx-small, medium, large, x-large and xx-large.
Enable byte-access to built-in Symbol and ZapfDingbats fonts.
0.029 2022-03-17
Fix issue #11 (PDF::Builder only).
Fix font changes for Markdown.
Fix <span rise> in convenience mode.
Handle <span background>.
0.028 2022-02-04
INCOMPATIBLE: In Pango mode, the direction of rise and lower
has been reversed and is no longer proportional to the font size.
In convenience mode you can use percentages and points..
INCOMPATIBLE: Extent boxes are now relative to top-left. This
is Pango compatible and makes the box fit when drawn at the
same coordinates the layout was rendered.
(Internal) Add extents method for CID fonts.
More Pango compatibility.
Add font properties direction and language.
Add 'pt' postfix for point sizes in markup.
0.027 2021-12-23
Pango compatibility (POSSIBLY INCOMPATIBLE):
get_{pixel_}extents now returns the layout extents in scalar
context. In this case, ink extents are not calculated.
Improve performance (15%) by cacheing bbox.
0.026 2021-12-22
Add tests for markup parsing.
Update example in README.
Add 'nosubset' property for fonts.
POSSIBLY INCOMPATIBLE: Fix issue #10. The difference will only
be noticable when you query the width for centered/right
aligned texts.
UNLIKELY INCOMPATIBLE: method set_pango_scale does now enable/disable.
The scaling is fixed to PANGO_SCALE (1024).
Fixed some issues with pango scaling.
Fix regression that sometimes tripled the resultant PDF.
0.025 2021-10-22
Add font config properties underline_thickness,
strikeline_position, strikeline_thickness, overline_position,
overline_thickness, and strikeline_position. Overriding the
font specified/calculated values may improve results for some
fonts. Note that strikeline_thickness and overline_thickness
will default to underline_thickness if set.
Withdraw a and link aliases for href. They may serve a
different purpose in the future.
0.024 2021-10-21
Retain case sensitivity for links.
Remove debugging info.
0.023 2021-10-21
Add support for underline, overline and strike, and their
colours.
Add support for hyperlinks (span attributes a, href and link).
Note that this is not part of the official Pango Markup
specification.
0.022 2021-10-04
Fix some reentrancy problems.
Update for PDF::API 2.042.
0.021 2021-07-09
Fix font cacheing problem with PDFAPI2.
Update links for pango documentation.
0.020 2021-05-18
Use common font cache for PDFAPI.
Handle some more weight variants.
Added testing PDF::Builder unless it is of an incompatible
version. As of 3.019 PDF::Builder changed the font metrics to
compatible values.
0.019 2020-08-16
Add support for C<< <span font_desc="..."> >>. See
tests/pdfapi3.pl for an example how to use this to embed RTL
texts. Note, however, that this currently relies on the native
harfbuzz library to correctly determine ('guess') the
characteristics of the text.
Eliminated backend loading in favour of derived classes.
Enable font caching for PDF::API2.
0.018.3 2020-05-19
Dropped testing with PDF::Builder. Text::Layout will continue
to work with PDF::Builder to the extent that it is compatible
with PDF::API2.
0.018.2 2020-05-09
Avoid testing PDF::Builder if it is of an incompatible
version. As of 3.018 PDF::Builder changed the font metrics to
incompatible values.
